Description

Technical Field

[0001] This application relates to the field of audio and video processing technology, and in particular to a video recording method, a video recording system, and a computer device. Background Technology

[0002] In the field of video creation and recording, users' demand for high-quality audio capture is growing, and optimizing sound recording with external devices has become an industry trend. Currently, shooting equipment often connects to audio devices via Bluetooth, utilizing the audio device's microphone to capture sound, thus improving the poor sound recording effect of traditional built-in microphones and enhancing video and audio quality.

[0003] However, in practical applications, such as collaborative creation and team interviews, users need to simultaneously record audio content from at least two audio devices belonging to multiple participants. But when the recording device is only connected to a single audio device in a multi-audio device network, it can only acquire the audio information of that device's user and cannot simultaneously record the conversations of other audio device users. This results in the loss of important information, limiting the application of video recording in multi-person interactive scenarios and making it difficult to meet the needs of simultaneous multi-source audio recording in complex scenarios. This technical limitation affects the integrity and richness of video content and increases the workload and difficulty of post-production audio processing. Summary of the Invention

[0071] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0072] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0074] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0075] In the field of video creation and recording, as users' demands for high-quality audio capture continue to increase, optimizing sound recording through external devices has become an industry trend. Currently, during video recording, shooting equipment can typically establish a communication connection with audio equipment using wireless communication technologies such as Bluetooth. This allows the audio equipment's built-in microphone to capture sound, clearly recording the user's speech into the video file. This effectively improves upon the poor sound recording quality of traditional shooting equipment's built-in microphones, thus enhancing both video and audio quality.

[0076] However, in real-world applications, such as collaborative creation, team interviews, and outdoor multi-person interactions, users often need to simultaneously record audio content from at least two audio devices belonging to multiple participants. When the filming device communicates with a single audio device in a multi-audio device network, the system can only acquire the audio data of the user corresponding to that connected audio device. It cannot synchronously record audio data transmitted between users on other audio devices in the multi-audio device network into the video, resulting in the loss of important audio data. This severely limits the application expansion of video recording in multi-person interactive scenarios and fails to meet users' needs for simultaneous recording of multiple sound sources in complex scenes. This technical limitation not only affects the integrity and richness of the video content but also brings additional workload and technical difficulty to the audio processing in post-production video production, urgently requiring solutions through technological innovation.

[0077] For the reasons stated above, in an exemplary embodiment, such as Figure 1 As shown, this application provides a video recording method applied to a shooting device. When an audio device is connected to the shooting device, the video recording method includes the following steps S102 to S104. Wherein:

[0078] S102, when the audio device is one of the audio devices in a multi-audio device network, the audio device receives audio data sent by the audio device during the video recording process of the shooting device;

[0079] S104 generates audio and video files based on audio data and video recorded by the shooting device;

[0080] Audio devices refer to devices capable of acquiring, processing, and transmitting audio. They can collect ambient sound or human voices through built-in pickup components and convert them into digital audio data. Then, they encode and encapsulate the audio data according to a predetermined communication protocol, adding necessary information such as addresses. This data is then exchanged with other audio devices via networks such as Bluetooth Mesh, or the integrated audio is sent to a shooting device, enabling audio transmission and sharing. Examples of audio devices include wireless microphones, Bluetooth headsets, smart speakers, and smart glasses. Shooting devices are devices capable of recording video, receiving audio, and synthesizing audio-visual files. They can capture scene images through a lens to record video; and by establishing connections with audio devices, they receive audio data collected and transmitted from multiple audio devices, synchronizing and synthesizing the received audio with their own recorded video to generate complete audio-visual files, meeting users' multimedia creation needs in complex scenarios. Examples of shooting devices include smartphones, camcorders, and action cameras. Audio data includes audio content collected by at least two audio devices in a multi-audio device network. Multi-audio device networking refers to multiple audio devices interconnected through a specific communication method, forming a network capable of audio transmission and interaction. Within this network, the audio devices can transmit data, allowing the recording device to receive audio data from multiple devices and thus capture the audio content from at least two of the user's audio devices into the video.

[0081] For example, as Figure 2 Taking the multi-audio device networking architecture shown in the diagram as an example, the camera and audio device C in the multi-audio device network communicate with each other. Audio devices A, B, and C can be interconnected through a network, such as a Bluetooth Mesh network, to achieve interactive transmission of audio data. Figure 3As shown in the interaction process between the shooting device and the audio device, after receiving audio data from other audio devices (audio device A and audio device B), audio device C can send this audio data, along with its own collected audio data, to the shooting device. This allows the shooting device to generate an audio-video file containing audio content collected by at least two audio devices in the multi-audio device network, based on this audio data and its own recorded video. Specifically, after each audio device collects audio data, it can encode and encapsulate the data according to a protocol such as Bluetooth Mesh, adding information such as source address and destination address for accurate transmission over the network. When audio devices A and B send the processed audio data to audio device C, audio device C will parse the data and confirm receipt according to the Bluetooth Mesh protocol. After establishing a Bluetooth connection with audio device C, the shooting device will negotiate the audio data transmission parameters, such as sampling rate and encoding format. After receiving and integrating the audio data from other audio devices (audio device A and audio device B), audio device C will send the data to the shooting device via the Bluetooth link according to the negotiated parameters. The recording device decodes and processes the received data according to the Bluetooth protocol, and finally synchronizes and synthesizes the audio data with the recorded video, thereby including the audio content collected by at least two audio devices of the user in the multi-audio device network into the video. In a specific embodiment, taking cycling headphones as the audio device and a camera as the recording device, the multi-audio device network is a cycling network. The camera is connected to one of the cycling headphones in the cycling network. During the camera's video recording, the camera can receive the audio data (such as conversation content) transmitted between the cycling headphones in the cycling network through the connected cycling headphones and include it in the video.

[0082] The aforementioned video recording method, by constructing a network of multiple audio devices and a collaborative working mechanism with the shooting device, overcomes the limitations of traditional single-audio device recording, achieving simultaneous acquisition and recording of audio content from at least two audio devices. Utilizing the multi-node transmission characteristics of the communication network, the shooting device can receive audio data from multiple audio devices, greatly enhancing the application capabilities of video recording in multi-person interactive scenarios, ensuring the integrity and richness of video content, and effectively meeting the diverse audio recording needs of users in complex scenarios.

[0083] In one exemplary embodiment, such as Figure 4 As shown, before the step of generating audio and video files based on audio data and video recorded by the shooting device, the shooting device also performs the following steps:

[0084] S402 performs secondary noise reduction processing on the received audio data;

[0085] S404 converts noise-reduced audio data into text information;

[0086] S406, based on keyword matching and semantic analysis, filters out dialogue content related to the dialogue topic from text information;

[0087] S408 combines the extracted audio data corresponding to the dialogue content with the video recorded by the shooting device to generate an audio and video file.

[0088] For example, after receiving audio data from multiple audio devices, the recording device performs secondary noise reduction and in-depth extraction of dialogue content. The recording device can employ more complex noise reduction algorithms, such as deep learning-based noise reduction models. These models, trained on a large amount of noisy audio data and clean audio data, can accurately identify and remove various complex noises, such as crowd noise and sudden high-frequency interference. The recording device also uses natural language processing (NLP) and speech recognition technologies to convert the received audio data into text information. Then, through keyword matching, semantic analysis, and other methods, it filters out content related to the dialogue topic and removes irrelevant background noise and environmental sound effects. For instance, in a multi-person interview video recording, the recording device receives audio data from multiple audio devices. Through the above processing, it accurately extracts the dialogue content of the guests, clearly preserving the questions and answers between the host and guests while filtering out irrelevant audio information such as slight noises from the audience and vehicle sounds outside the window. The shooting equipment combines the audio data, which has undergone noise reduction and dialogue content extraction, with the video to generate an audio-visual file. The audio portion retains only clear and effective dialogue content, greatly improving the audio quality and information transmission efficiency of the video in multi-person interactive scenarios, and meeting users' needs for professional-grade audio-visual creation.

[0089] In one exemplary embodiment, such as Figure 5 As shown, audio and video are generated based on audio data and video recorded by the shooting device, including:

[0090] S502, according to preset audio data processing rules, splits the audio data into multiple audio tracks;

[0091] S504 performs speaker matching based on multiple audio track data, and the corresponding audio and video frames include speaker information.

[0092] Among them, the preset audio data processing rules can refer to a series of pre-set criteria and methods used when splitting audio data into multiple audio tracks, with the aim of achieving effective processing and subsequent analysis of audio data. Specifically, they can include the following rules: (1) Data source differentiation rules: Based on the identification or address of the audio device, audio data from different audio devices are separated and correspond to different audio tracks. For example, by identifying the Bluetooth address or unique code of audio device A, audio device B and audio device C, the audio data collected by each device is assigned to different audio tracks, thus clarifying the source of each audio track data, i.e., the audio device used by the corresponding speaker. (2) Audio feature extraction rules: Features such as frequency features and time domain features are extracted from the audio data so that the audio can be further classified and processed based on these features. For example, based on the frequency range, speech rate and tone of different speakers, audio segments with similar features are divided into the same audio track, which helps with subsequent speaker matching and identification. (3) Data format conversion rules: The received raw audio data is converted into a format suitable for processing and storage. For example, audio data with different sampling rates and encoding formats can be uniformly converted into a standard format that can be recognized and processed by the shooting device or subsequent processing system, such as a uniform sampling rate and a preset encoding method, to ensure the consistency and compatibility of the data during processing. (4) Time synchronization rules: Add timestamp information to the audio data to ensure that the audio data collected by different audio devices can be accurately synchronized in time. Since multiple audio devices may start collecting audio at different times, the audio data can be aligned on the time axis through time synchronization rules, so that the generated audio and video can maintain the synchronization of audio and video, and avoid the problem of audio and video being out of sync. The audio data is split into multiple independent data tracks according to certain rules. In the scenario of multi-audio device networking, the audio data collected by different audio devices will be processed into different audio track data. For example, the audio data collected by audio device A, audio device B and audio device C will each correspond to an audio track data, so that audio from different sources can be processed and managed independently, which makes it convenient to distinguish the voices of different speakers according to different audio tracks. In a multi-audio device network environment, a speaker refers to a user who speaks through their respective audio devices, and whose voice is captured and included in the video. In the example above, the users using audio devices A, B, and C are different speakers. Each speaker's voice is captured through their respective audio device, transmitted and processed over the network, and becomes the audio source in the audio-visual content. Speaker information refers to various descriptive contents related to the speaker; in this embodiment, it mainly refers to information associated with the audio-visual images that can identify the speaker.This might include the speaker's identification (such as username, ID, etc.), the timestamp of the speech (to record the time and position of the speech in the video), and the speaker's location information in the frame (if there is a corresponding marker in the video frame). This information allows viewers to clearly know which speaker is speaking at different points in the video, thus better understanding the video content.

[0093] For example, after receiving audio data transmitted by an audio device, which contains audio content collected by at least two audio devices in a multi-audio device network, the capturing device processes it according to preset audio data processing rules. For instance, by using data source differentiation rules, audio data from different audio devices (such as audio device A, audio device B, and audio device C) are separated based on the audio device's identifier or address, corresponding to different audio tracks. Simultaneously, audio feature extraction rules are used to extract features such as frequency and time domain of the audio, grouping audio segments with similar features into the same audio track. Furthermore, data format conversion rules can be used to unify the original audio data into a standard format suitable for processing and storage. Time synchronization rules are used to add timestamps to the audio data, achieving accurate time synchronization of audio data from different audio devices, thus completing the operation of splitting the audio data into multiple audio tracks. Then, based on these audio track data, speaker matching is performed, associating audio tracks with speakers. Simultaneously, combined with the audio and video footage, speaker information such as speaker identification, speaking timestamps, and screen position is integrated, ultimately generating audio and video containing speaker information.

[0094] In this embodiment, audio data is split by preset audio data processing rules and speaker matching is performed based on the processed audio track data. Information such as speaker identity, time, and location is integrated into the audio and video picture, which greatly improves the clarity and comprehensibility of the video content. It makes it convenient for users to quickly identify different speakers and their speech content in multi-person interactive scenarios. It provides a high-quality and intelligent audio and video processing solution for application scenarios such as video creation, meeting recording, and multi-person interviews, effectively meeting users' needs for efficient management and presentation of audio and video information in complex scenarios.

[0095] In one exemplary embodiment, the audio bandwidth of the audio device is allocated to the shooting device and the network of multiple audio devices based on a first preset ratio.

[0096] Audio bandwidth refers to the communication capability of an audio device when transmitting audio data. A larger bandwidth means more audio data can be transmitted per unit time, which translates to supporting higher quality and richer audio content transmission. For example, high bandwidth allows audio data to contain more detail and a wider frequency range, making the sound clearer and fuller. The first preset ratio refers to a pre-set proportional value used to allocate the audio bandwidth of the audio device to the shooting device and other audio devices in a multi-audio device network. This ratio allows for reasonable coordination of audio data transmission between the audio device, the shooting device, and other audio devices, ensuring that each device receives sufficient bandwidth to complete audio acquisition, transmission, and processing operations.

[0097] For example, in a single-chip Bluetooth audio device, since it typically uses only one chip to handle Bluetooth communication and audio encoding / decoding, its audio bandwidth is relatively limited because the processing and communication capabilities of a single chip have certain limits. For instance, it may only support audio data transmission at a fixed sampling rate and encoding format. A common single-chip Bluetooth audio device might only support enough audio bandwidth for ordinary music playback or everyday calls. Assuming the total audio bandwidth of this single-chip Bluetooth audio device is 100 units (this unit is assumed for ease of understanding; in practice, it might be measured in bit rate, etc.), and the first preset ratio is set to allocate 70% to the shooting device and 30% to other audio devices in a multi-audio device network, then during audio data transmission, 70 units of bandwidth will be used to transmit audio to the shooting device to ensure that the shooting device can receive the audio data collected by this audio device; the remaining 30 units of bandwidth will be used for audio interaction with other audio devices, enabling audio transmission and sharing among multiple audio devices. For dual-chip Bluetooth audio devices, the enhanced processing and communication capabilities compared to single-chip devices, due to the presence of two chips, result in a larger audio bandwidth. These two chips can work independently or collaboratively, supporting higher sampling rates and more complex encoding formats, thus transmitting more audio data. For example, a dual-chip Bluetooth audio device can simultaneously handle high-definition audio recording and transmission, as well as stable audio communication with multiple devices. Assuming the total audio bandwidth of the dual-chip Bluetooth audio device is 200 units (increased due to stronger processing power), and the initial preset ratio is set to 50% allocated to the recording device and 50% to other audio devices, then 100 units of bandwidth will be used to transmit audio to the recording device (equivalent to one chip transmitting audio to the recording device), providing richer and higher-quality audio data; 100 units of bandwidth will be used for audio interaction with other audio devices (equivalent to another chip transmitting audio to other audio devices), making audio transmission between multiple audio devices smoother and better enabling the synchronous acquisition and transmission of audio content from multiple users using at least two audio devices.

[0098] In this embodiment, by allocating bandwidth according to a first preset ratio, resources can be rationally planned based on the hardware characteristics of the audio devices (such as the difference in processing power between single-chip and dual-chip devices). This ensures that the shooting device has sufficient bandwidth to acquire high-quality and complete audio information when receiving audio data from a single audio device, avoiding audio loss or quality degradation due to insufficient bandwidth. Simultaneously, the bandwidth allocated for interaction between the audio device and other audio devices within the network ensures stable transmission of audio data between multiple audio devices, enabling the shooting device to ultimately receive audio data that fully covers the audio content collected by at least two audio devices from multiple users. Furthermore, this bandwidth allocation mechanism optimizes data transmission efficiency, reduces transmission conflicts and latency, and improves audio and video synchronization. This helps the shooting device efficiently acquire and generate high-quality audio and video containing rich audio content collected by at least two audio devices, better meeting the shooting needs in multi-user interactive scenarios.

[0099] In addition to the problems mentioned above, in some existing technical solutions, when an audio device is connected to a shooting device, the audio transmission channel of the audio device is always occupied by the shooting device. At this time, even if the user wants to answer calls from other devices or receive map broadcasts or music from other devices through the audio device, it will not be possible because the audio transmission channel of the audio device is occupied by the shooting device. In another existing technical solution, when the user is answering calls from other devices or listening to map broadcasts or music from other devices through the audio device, and the user starts recording video through the shooting device, the audio device cannot provide audio recording function during the video recording process because the mobile phone is occupying the audio transmission channel of the audio device.

[0100] For the reasons stated above, in an exemplary embodiment, such as Figure 6 As shown, the above video recording method also includes:

[0101] S602, under the condition that the first preset condition is met, records sound through the microphone of the shooting device.

[0102] The first preset condition can refer to a combination of situations that may cause the audio device microphone to be unable to effectively record sound for the shooting device. Specifically: (1) When there is a higher priority of other devices for the audio device microphone than the shooting device for the audio device microphone, the audio device microphone will be occupied by other devices. For example, in some scenarios where multiple devices work together, the audio device may be connected to mobile terminal devices such as mobile phones and computers at the same time. When the mobile phone receives an important voice call or the computer performs a voice command recognition task with higher priority, it will occupy the audio device microphone first. At this time, the shooting device cannot use the audio device microphone to record sound, thus satisfying the first preset condition. (2) Unstable audio recording by the audio device microphone will also trigger the first preset condition. This may be caused by the failure of the audio device itself, unstable Bluetooth connection, interference in the surrounding environment, etc. For example, if the microphone component of the audio device is damaged, the collected audio data will have noise, distortion, or low volume; or the Bluetooth signal will be interfered with, causing the audio data to be lost or delayed during transmission, affecting the normal acquisition and processing of audio by the shooting device. These situations mean that the audio device microphone cannot reliably record sound for the shooting device, thus satisfying the first preset condition. (3) In addition to the aforementioned issues of device priority and sound reception stability, there may be other situations that prevent the audio device microphone from being used by the shooting device for sound reception. For example, there may be errors in the communication protocol between the audio device and the shooting device, which may prevent the shooting device from correctly recognizing or receiving the audio data collected by the audio device microphone; or the audio input interface of the shooting device may malfunction and fail to receive the signal from the audio device microphone. These situations can also be included in the scope of the first preset condition. In short, the first preset condition is a set of conditions that comprehensively considers multiple factors and aims to determine whether the audio device microphone can provide sound reception for the shooting device normally and stably. When any situation that may affect the audio device microphone from receiving sound for the shooting device occurs, the first preset condition is met. At this time, the shooting device will use its own microphone to receive sound to ensure that stable audio data can be obtained.

[0103] For example, a combination of situations that prevent the audio device's microphone from effectively recording audio for the shooting device, such as the audio device's microphone being occupied with high priority by other devices, unstable sound reception (e.g., audio device malfunction, Bluetooth interference), communication protocol errors, or audio interface malfunction of the shooting device, is defined as the first preset condition. Figure 5As shown in the interaction between the shooting device and the audio device, when the first preset condition is met, the shooting device no longer forcibly occupies the audio channel of the audio device, but switches to its own microphone for sound recording, breaking the inherent pattern of the shooting device always occupying the audio channel of the audio device. This method allows the shooting device to flexibly adjust the audio acquisition method according to the actual sound recording environment and device status. It avoids the predicament of the shooting device being unable to record sound due to the audio channel of the audio device being occupied by other devices, and also ensures that stable audio data can still be obtained through the microphone of the shooting device when the microphone of the audio device is not working properly, thus improving the reliability and adaptability of the audio acquisition of the shooting device.

[0104] In this embodiment, intelligent switching of the audio recording mode of the shooting device is achieved by setting a first preset condition. This breaks the limitation that the shooting device always occupies the audio channel of the audio device. When the audio device microphone cannot effectively record audio due to various reasons such as high priority occupation by other devices, its own failure, Bluetooth interference, communication protocol errors, or interface failure of the shooting device, the shooting device can switch to its own microphone in time to ensure uninterrupted audio acquisition. This mechanism greatly improves the adaptability of the shooting device in complex usage scenarios, avoids audio data loss due to external factors or equipment problems, ensures the stability and reliability of audio acquisition during video recording, provides users with a smoother and more efficient shooting experience, and also broadens the application scope of the shooting device in multi-device collaboration and complex environments.

[0105] In one exemplary embodiment, after activating the microphone of the shooting device, the method further includes:

[0106] Output the first reminder message.

[0107] The first reminder content can refer to the content used to remind the camera of changes in the sound recording method, such as "The camera's microphone has been turned on."

[0108] In this embodiment, by outputting a first reminder message after the microphone of the shooting device is turned on, the user can be promptly and clearly informed that the sound recording mode of the shooting device has changed. This avoids the user from misjudging the video and audio quality or encountering problems in subsequent processing due to not noticing the change in sound recording mode. For example, the user can adjust the shooting distance, volume, and other operations in a timely manner to ensure the audio acquisition effect.

[0109] In one exemplary embodiment, such as Figure 6 As shown, the above video recording method also includes:

[0110] S604, when the second preset condition is met, the microphone of the shooting device stops recording sound and receives the audio sent by the microphone of the audio device.

[0111] The second preset condition can refer to a combination of situations that cause the microphone of the shooting device to stop recording and switch to the microphone of the audio device to record. For example: (1) Equipment failure elimination: The microphone of the audio device may have been unable to work properly due to its own hardware failure (such as component damage, poor contact) or software problem (such as abnormal driver), causing the shooting device to use its own microphone to record. When these failures are eliminated and the microphone of the audio device returns to normal working status, the second preset condition is met. (2) Elimination of interference factors: Interference factors in the surrounding environment (such as strong electromagnetic interference, other wireless signal interference) may affect the recording effect of the microphone of the audio device, causing the shooting device to have to switch to its own microphone to record. When these interference factors disappear, the microphone of the audio device can record stably and clearly, thus meeting the second preset condition. For example, when the user leaves the area with strong signal interference, the Bluetooth signal of the microphone of the audio device returns to stability. (3) The mobile terminal audio demand ends, which may include: ① The mobile terminal audio transmission task is completed: The mobile terminal may have had an urgent and high-priority audio task (such as important voice calls, real-time voice broadcasts), causing the audio device to prioritize serving the mobile terminal, and the shooting device can only use its own microphone to record. When these tasks are completed, the mobile terminal's need for the audio device microphone disappears, and the audio device can resume providing audio acquisition services to the shooting device, thus satisfying the second preset condition. For example, when the mobile terminal's voice call ends, it no longer occupies the audio device microphone. ② Change in demand priority: Originally, the mobile terminal's audio demand priority was higher than that of the shooting device, but as the situation changes, the mobile terminal's audio demand is no longer urgent or its importance decreases, while the shooting device's demand for audio acquisition relatively increases. At this time, the audio device can reallocate the audio channel resources to the shooting device, thus satisfying the second preset condition. For example, when the mobile terminal's voice command recognition is completed, there are no new high-priority audio tasks. (4) User manual intervention: The user may manually choose to stop the shooting device from using its own microphone to record sound according to the actual shooting needs, and start recording sound through the audio device microphone again. This user-initiated operation can also be considered as a situation of the second preset condition. For example, the user finds that the audio device microphone's sound recording effect is more suitable for the current shooting scene, so they manually switch back to the audio device microphone to record sound. In summary, the setting of the second preset condition takes into account various factors such as the working status of the audio device's microphone, the audio requirements of the mobile terminal, and the user's operation. It aims to flexibly adjust the sound recording method of the shooting device according to the actual situation in order to obtain the best audio acquisition effect.

[0112] In this embodiment, the shooting device can flexibly adjust its audio recording method according to actual conditions. When the second preset condition is met, such as the audio device's microphone returning to normal operation, external interference being eliminated, the mobile terminal's audio demand ending, or user manual intervention, the shooting device can promptly stop its own microphone from recording and instead receive audio from the audio device's microphone, thereby optimizing the audio acquisition effect. This helps the shooting device obtain clearer and higher-quality audio in different scenarios, improving the overall shooting quality. It also demonstrates the intelligence and adaptability of the shooting device in audio management, better meeting the diverse shooting needs of users.

[0113] In one exemplary embodiment, after the microphone of the shooting device stops picking up sound and receives the audio transmitted by the microphone of the audio device, the method further includes:

[0114] Output the second reminder message.

[0115] The second reminder can refer to information indicating a change in the recording method of the camera, such as "The audio device microphone has been turned on."

[0116] In this embodiment, after the shooting device completes the switching of the audio recording mode—that is, stops the shooting device's microphone from recording and begins receiving audio from the audio device's microphone—outputting the second reminder message promptly and clearly informs the user of this change. This helps the user to keep track of the shooting device's working status in real time, avoiding situations where the audio quality does not meet expectations during subsequent shooting due to a lack of awareness of the change in the audio recording mode. For example, if the user does not receive a reminder, they may mistakenly believe that the shooting device is still using its own microphone, thus incorrectly adjusting the shooting position or environment, affecting the audio acquisition effect. The second reminder message allows the user to clearly understand the current audio recording status, enabling more targeted shooting operations and ensuring the accuracy and reliability of audio acquisition during video recording.

[0117] In one exemplary embodiment, such as Figure 7 As shown, when the audio device is also used to connect to a mobile terminal, the first preset condition includes:

[0118] S702 receives the first notification message sent by the audio device;

[0119] The first notification message is used to instruct the audio device and mobile terminal to transmit audio; or...

[0120] S703, received the first user operation;

[0121] The first user action is used to instruct the camera to turn on the microphone.

[0122] The first notification message is a message generated and sent by the audio device under preset conditions. When the audio device is currently transmitting audio to the first device and also needs to transmit audio to the second device, and a third preset condition is met, the audio device generates the first notification message to inform the relevant device (such as the camera device) to perform corresponding operations (such as turning on the camera device's microphone). The third preset condition refers to the priority of audio transmission between the audio device and the mobile terminal being higher than the priority of audio transmission between the audio device and the camera device, used to determine whether a switching of audio recording mode is necessary. Specifically, when the first device is the camera device and the second device is the mobile terminal: the audio device is currently transmitting audio to the camera device. When a mobile terminal needs to transmit audio to the audio device, and the third preset condition of higher priority for mobile terminal audio transmission is met, the audio device generates the first notification message. This first notification message informs the camera device that because the audio device must prioritize the audio transmission needs of the mobile terminal, the camera device needs to take corresponding measures (turn on its own microphone). This means that in this scenario, the audio transmission needs of the mobile terminal have higher priority. For example, when a mobile terminal receives an urgent voice call or important voice command, the audio device needs to prioritize its service, while the audio transmission needs of the shooting device are secondary. When the first device is a mobile terminal and the second device is a shooting device: the audio device initially transmits audio to the mobile terminal. When the shooting device also needs to transmit audio to the audio device, if the third preset condition that the mobile terminal's audio transmission priority is higher than the shooting device's is met, the audio device will also generate a first notification message. However, this first notification message is mainly to inform the shooting device that its audio transmission priority is lower, and it may need to turn on its microphone to record sound to ensure normal audio acquisition. Again, it emphasizes that the mobile terminal's audio transmission priority is higher than the shooting device's. For example, if the mobile terminal is conducting a real-time voice broadcast, the requirements for audio real-time performance and stability are very high, while the shooting device's audio acquisition needs are relatively less urgent. Therefore, the audio device prioritizes the mobile terminal's audio transmission, and the shooting device needs to make corresponding adjustments based on the first notification message. In addition, when the audio device is transmitting audio to the shooting device and needs to transmit audio to the mobile terminal, the audio device can also directly generate and send a first notification message to the shooting device. The first notification message is mainly used to inform the shooting device that the mobile terminal needs to occupy the audio channel of the audio device to transmit audio. When the shooting device receives the first notification message output in this situation, it also meets the first preset condition, and the shooting device will also pick up sound through the microphone of the shooting device.

[0123] The first user action is a user-initiated command to intervene in the audio recording settings of the shooting device, based on their own needs and judgment of the device's audio transmission status. When the audio device is simultaneously connected to both the shooting device and the mobile terminal, and the user realizes that the current audio transmission situation requires the shooting device to switch its recording mode, they can instruct the shooting device to activate its microphone by executing the first user action. This action breaks the mechanism that relies solely on the device to automatically determine the audio transmission priority, giving the user the right to directly control the recording settings of the shooting device. For example, in a real shooting scenario, even if the audio transmission priority between the audio device and the mobile terminal is not higher than that between the audio transmission and the shooting device, if the user believes that using the shooting device's microphone is more suitable for the shooting needs based on the on-site sound collection requirements, they can trigger the first user action by clicking a specific button on the shooting device's screen, pressing a physical button, issuing a voice command, or changing settings in the relevant application on the mobile terminal. Once the shooting device receives this action, it will activate the microphone according to the user's instruction, switching the recording mode, thus making the recording settings of the shooting device more in line with the user's actual usage scenario and personalized needs.

[0124] For example, the audio device in this embodiment is as follows: Figure 8 Taking audio device C in a multi-audio device network as an example in the illustrated application scenario, audio device C is not only connected to the camera device but also interacts with other audio devices in the multi-audio device network, exchanging audio data. When an audio device is currently transmitting audio to the camera device but also needs to transmit audio to a mobile terminal, and the mobile terminal's audio transmission priority is higher than that of the camera device, the audio device will generate a first notification message. For example, because the mobile terminal may have urgent voice calls or important voice commands, its priority is higher. The audio device sends the first notification message to the camera device, informing it that it needs to switch its audio recording mode. After receiving the first notification message, the camera device turns on its own microphone to record audio. This breaks the situation where the camera device always occupies the audio channel of the audio device, allowing the camera device to continue audio collection through its own microphone without affecting the audio device's service to the mobile terminal, thus meeting the needs of the mobile terminal. Meanwhile, audio interaction between other audio devices in the multi-audio device network remains unaffected, and the shooting device can also acquire audio data collected by its own microphone, ensuring the integrity of audio during video recording and achieving good compatibility between the shooting device, audio devices, mobile terminals, and the multi-audio device network. In addition, the audio devices in this embodiment can also be as follows: Figure 8In the illustrated application scenario, audio device C, connected only to the mobile terminal and the camera, can perform the following actions: If the audio device is currently transmitting audio to the camera, but the mobile terminal has a higher priority audio transmission requirement (such as real-time audio streaming or other tasks requiring high audio real-time performance and stability), the audio device generates a first notification message and sends it to the camera. Upon receiving the notification, the camera activates its own microphone, no longer occupying the audio device's audio channel, allowing the audio device to prioritize the mobile terminal's audio transmission needs. Conversely, if the audio device is initially transmitting audio to the mobile terminal, and the camera needs audio transmission but the mobile terminal has a higher priority, the audio device also sends a first notification message to the camera, prompting the camera to automatically activate its microphone for audio capture. In this way, the camera no longer constantly occupies the audio device's audio channel but can flexibly switch recording methods based on the audio device's first notification message. When the audio device is connected to the mobile terminal, it effectively accommodates the mobile terminal's needs, ensuring smooth audio tasks on the mobile terminal, while the camera can continue to capture audio using its own microphone, guaranteeing effective audio acquisition during video recording.

[0125] In addition, a dedicated microphone activation button is provided on the shooting device. Users can press this button to send a command to the shooting device to activate the microphone. For example, some professional shooting devices have independent audio-related buttons on the side or top of the camera body, which users can press to control the microphone's on / off state. Secondly, users can access the shooting device's settings menu, find the microphone activation option in the audio settings, and select it. For example, ordinary digital shooting devices can be activated by pressing the "Menu" button, finding "Audio Settings" or "Recording Settings," and then activating the microphone function. In some embodiments, when the first notification message sent by the audio device is output when the audio device is currently transmitting audio with the shooting device and also needs to transmit audio with the mobile terminal, the shooting device can also output a prompt message on its operation interface based on this first notification message, such as, "The mobile terminal needs to transmit audio with the audio device. Do you want to activate the shooting device's microphone for recording?" This informs the user that due to the adjustment of audio transmission priorities between devices, the shooting device needs to activate the microphone to adapt to the new audio transmission requirements. At this time, the user can respond by clicking the "Confirm Activation" button on the screen, inputting the "Activation" command via voice, or other preset operation methods. If the user performs this action, it indicates that the user agrees to activate the microphone of the recording device. The recording device will then activate the microphone and record audio based on this instruction. If the user does not perform this action or refuses the action, the recording device will not activate the microphone and will maintain the current audio recording state. For details on the interaction between the recording device and the audio device, please refer to [link / reference]. Figure 7 As shown.

[0126] In this embodiment, the shooting device can promptly understand the adjustment of audio transmission priority between devices based on the first notification information sent by the audio device, thereby flexibly switching the audio recording mode to avoid constantly occupying the audio channel of the audio device and ensuring that the high-priority audio needs of the mobile terminal are met first. Simultaneously, the first user operation grants the user the right to directly control the audio recording settings of the shooting device, allowing the user to flexibly adjust them according to actual shooting needs, making the audio recording settings of the shooting device more suitable for personalized scenarios. Furthermore, the shooting device can also output prompts on the operation interface based on the first notification information, allowing the user to participate in decision-making, further enhancing the user's control over the audio recording of the shooting device, ensuring the effective acquisition and integrity of audio during video recording, and achieving good compatibility with audio devices, mobile terminals, and multi-audio device networks.

[0127] In one exemplary embodiment, the video recording method further includes:

[0128] In the absence of receiving the first notification message from the audio device or the first user operation, the audio is picked up through the microphone of the audio device.

[0129] The failure to receive the first notification message from the audio device may mean that the audio device does not need to transmit audio to the second device while it is currently transmitting audio to the first device; or, the third preset condition is not met at this time, that is, the priority of the audio device transmitting audio to the mobile terminal is lower than or equal to the priority of the audio device transmitting audio to the shooting device; or, the user has not performed the relevant operation of turning on the microphone of the shooting device.

[0130] For example, when the audio device is transmitting audio to the shooting device (first device), if it does not need to transmit audio to the mobile terminal (second device), it means that the audio channel resources of the audio device are not occupied by the audio needs of other devices. In this case, the audio device can concentrate all its audio transmission capabilities on serving the shooting device, allowing the shooting device to successfully record sound through the audio device's microphone. Because there are no other devices' audio transmission tasks interfering with the audio transmission link between the audio device and the shooting device, the audio device's microphone can focus on collecting sound and stably transmitting the audio data to the shooting device, ensuring the normal sound recording of the shooting device and meeting the audio requirements of video recording. When the priority of audio transmission between the audio device and the mobile terminal is equal to the priority of audio transmission between the audio device and the shooting device, although the mobile terminal may have audio transmission needs, since its priority is the same as the shooting device, there is no situation where the audio device needs to prioritize serving the mobile terminal and abandon audio transmission for the shooting device. The audio device does not need to interrupt or change its audio transmission to the other party to satisfy one party. Therefore, the audio device can continue to maintain audio transmission with the shooting device, allowing the shooting device to record sound through the audio device's microphone, and also ensuring that the audio device is compatible with the mobile terminal's audio transmission. This ensures the stability of the recording device during audio acquisition, preventing unnecessary switching of the recording method due to priority conflicts. This allows the recording device to continuously and stably acquire audio data from the audio device's microphone for video recording. When the audio transmission priority between the audio device and the mobile terminal is lower than that between the audio device and the recording device, the audio device prioritizes audio transmission with the recording device. The audio channel resources of the audio device are preferentially allocated to the recording device to meet its audio acquisition needs. Therefore, the recording device can record audio through the audio device's microphone, and this recording method is not interfered with by the mobile terminal's audio transmission requirements. The audio device uses its primary audio transmission capabilities for interaction with the recording device, ensuring that the recording device acquires high-quality audio data, thereby guaranteeing the integrity and quality of the audio portion in video recording. If the user does not activate the recording device's microphone, the recording device will use the audio device's microphone, prioritizing the recording process.

[0131] In this embodiment, when the first notification message from the audio device or the first user is not received, the shooting device can rationally utilize the audio device's microphone to capture sound according to different situations. When the audio device does not need to transmit audio to the mobile terminal, the shooting device can exclusively occupy the audio channel resources of the audio device, ensuring stable and uninterrupted sound capture and meeting the audio requirements of video recording. When the audio device, mobile terminal, and shooting device have equal audio transmission priorities, the shooting device does not need to switch sound capture methods, maintaining the stability of audio acquisition and avoiding unnecessary changes that could affect data acquisition. When the mobile terminal's audio transmission priority is lower than that of the shooting device, the audio device will prioritize serving the shooting device, allowing the shooting device to obtain high-quality audio data and ensuring the integrity and quality of the video audio portion. This series of mechanisms enables the shooting device to efficiently and stably capture sound through the audio device's microphone under different device audio transmission priority scenarios, improving the adaptability of the shooting device in multi-device connection scenarios and the reliability of audio acquisition.

[0132] In one exemplary embodiment, such as Figure 7 As shown, when the audio device is also used to connect to a mobile terminal, the second preset condition includes:

[0133] S705 receives a second notification message sent by the audio device;

[0134] The second notification message is used to instruct the audio device and the recording device to transmit audio; or...

[0135] S706, received a second user operation;

[0136] The second user action is used to instruct the camera's microphone to be turned off.

[0137] The second notification message can refer to the audio device generating and sending an audio message when the mobile terminal stops transmitting audio to the audio device, but the audio device still needs to transmit audio to the shooting device. When the audio device is simultaneously connected to both the mobile terminal and the shooting device, and the mobile terminal stops transmitting audio to the audio device (e.g., after completing a voice call or ending a live voice broadcast), if the audio device still needs to transmit audio to the shooting device, a second notification message will be generated. This message clearly indicates that the current audio transmission environment of the shooting device has changed, and the audio transmission focus of the audio device will shift to interaction with the shooting device. The shooting device can adjust its audio pickup method accordingly, such as turning off its own microphone and instead receiving audio from the audio device's microphone. The second user operation refers to an operation actively performed by the user based on their judgment of the shooting scene and audio pickup needs to change the audio pickup method of the shooting device. When the audio device is connected to both the shooting device and the mobile terminal, the user may, based on the actual situation, believe that the shooting device no longer needs to use its own microphone and should instead receive audio through the audio device's microphone. In this case, the user can execute a second user operation to instruct the shooting device's microphone to be turned off. For example, during filming, if the user finds the surrounding environment relatively quiet, the audio device's microphone sufficient to clearly capture sound, and the filming device's own microphone might introduce unwanted background noise, or if the user desires a specific audio effect through the audio device's microphone, they can trigger a second user operation through the filming device's interface (such as clicking a specific button on the screen, selecting a relevant option in the menu), using physical button combinations on the filming device, or using voice commands. Once the filming device receives the operation command, it will mute its own microphone as instructed by the user and switch to audio capture through the audio device's microphone.

[0138] For example, when an audio device is connected to both a shooting device and a mobile terminal, the audio device monitors the audio transmission status with the mobile terminal in real time during its operation. When the mobile terminal stops transmitting audio to the audio device—for example, when the mobile terminal disconnects from the audio device, or when the mobile terminal completes a voice call or ends a live audio broadcast—and the shooting device still needs to transmit audio to the audio device, the audio device will automatically output a second notification message based on this status change. This second notification message informs the shooting device that the mobile terminal's need for audio transmission from the audio device has ended, and the shooting device can then switch its recording mode. Upon receiving this second notification message, the shooting device will perform the corresponding operation: stop its own microphone from recording and switch to the audio device's microphone to record audio, and receive the audio data sent by the audio device's microphone. Alternatively, after receiving the second notification message, the shooting device will output a prompt message on its user interface, such as, "The mobile terminal has stopped audio transmission. Do you want to stop the shooting device's microphone and switch to the audio device's microphone?", thus guiding the user to decide whether to switch the recording mode through subsequent user operations. When the user confirms and selects to stop the recording device's microphone from recording and switch to the audio device's microphone, the recording device will turn off its microphone.

[0139] In this embodiment, the second notification information enables information interaction and collaborative work between the audio device and the shooting device. The shooting device can accurately adjust its own audio recording mode in a timely manner according to changes in the audio transmission status between the mobile terminal and the audio device. This ensures the smooth and reasonable allocation of audio acquisition in multi-device connected scenarios, meeting the audio needs of different devices at different stages. Furthermore, by receiving a second user operation, the shooting device can decide whether to stop its own microphone and receive audio from the audio device's microphone based on the user's explicit instructions. This respects the user's subjective wishes, making the shooting device's audio recording settings more aligned with the user's actual shooting needs. It also ensures that the switching of the shooting device's audio recording mode under different device audio transmission states is reasonable and meets user expectations, effectively improving the user's operating experience and satisfaction with the shooting device.

[0140] In one exemplary embodiment, sound is captured via the microphone of the shooting device, including:

[0141] When the shooting device is equipped with dual-track audio recording, the first audio track is configured as a silent frame, and the second audio track is configured to record audio from the microphone of the shooting device; wherein, the first audio track is the audio track used for recording audio from the microphone of the audio device, and the second audio track is the audio track used for recording audio from the microphone of the shooting device.

[0142] Dual-track audio recording refers to the ability of the shooting device to process two audio tracks simultaneously. These two tracks correspond to different audio sources: the audio source's microphone and the shooting device's microphone. Dual-track recording allows the shooting device to acquire audio information more flexibly. When it's necessary to switch recording methods, such as switching from the audio source's microphone to the shooting device's microphone, the first audio track (corresponding to the audio source's microphone) can be set to a silent frame, while the second audio track (corresponding to the shooting device's microphone) can be configured accordingly to begin normal recording. This enables the switching and management of different audio sources to meet the diverse audio acquisition needs in different scenarios.

[0143] In this embodiment, when the audio device microphone is disconnected, its corresponding audio track is set to a silent frame. This cleverly fills in missing audio without interrupting the audio acquisition of the shooting device, avoiding incomplete audio data due to interrupted audio source. When the audio device microphone is reconnected, the pre-set silent frame ensures precise synchronization of the two audio tracks on the timeline, allowing for a natural transition between the audio device microphone's pickup and the shooting device microphone's pickup, avoiding audio misalignment, stuttering, and other issues. This effectively improves the fault tolerance and stability of the shooting device in complex audio acquisition environments, ensuring high-quality audio and video output regardless of temporary malfunctions of the audio acquisition device or the need to switch between different audio sources, providing users with a consistent and smooth audio and video recording experience.

[0144] In one exemplary embodiment, this application also provides a video recording method, such as... Figure 3 As shown, when applied to an audio device and connected to a shooting device, the method includes:

[0145] S301, when the audio device is one of the audio devices in a multi-audio device network, audio data is sent to the shooting device during the video recording process;

[0146] The audio data is used by the shooting device to generate audio and video files based on the audio data and the video recorded by the shooting device; the audio data includes the audio content collected by at least two audio devices in a multi-audio device network.

[0147] For example, as Figure 2 Taking audio device C in a multi-audio device network as an example in the illustrated application scenario, the camera is connected to audio device C via Bluetooth. Audio devices A, B, and C are interconnected through a Bluetooth Mesh network to form a network, enabling the interactive transmission of audio data. Figure 3As shown in the interaction process between the shooting device and the audio device, after receiving audio data from other audio devices (audio device A and audio device B), audio device C can send this data, along with its own collected audio data, to the shooting device. This allows the shooting device to generate an audio-visual system containing audio content collected by at least two audio devices in the multi-audio device network, based on this audio data and its own recorded video. Specifically, after each audio device collects audio data, it encodes and encapsulates the data according to the Bluetooth Mesh protocol, adding information such as source address and destination address for accurate transmission over the network. When audio devices A and B send the processed audio data to audio device C, audio device C parses the data and confirms receipt according to the Bluetooth Mesh protocol. After establishing a Bluetooth connection with audio device C, the shooting device negotiates the audio data transmission parameters, such as sampling rate and encoding format. After receiving and integrating the audio data from other audio devices, audio device C sends the data to the shooting device via the Bluetooth link according to the negotiated parameters. The recording device decodes and processes the received data according to the Bluetooth protocol, and finally synchronizes and synthesizes the audio data with the recorded video, thereby including the audio content collected by at least two audio devices of the user in the multi-audio device network into the video.

[0148] The aforementioned video recording method, by constructing a network of multiple audio devices and a collaborative working mechanism with the shooting device, overcomes the limitations of traditional single-audio device recording, enabling simultaneous acquisition and recording of audio content from multiple users using at least two audio devices. Utilizing the multi-node transmission characteristics of Bluetooth Mesh networks, audio devices connected to the shooting device can collect and send audio data from multiple devices to the shooting device, allowing the shooting device to receive audio data from multiple audio devices. This significantly enhances the application capabilities of video recording in multi-user interactive scenarios, ensuring the integrity and richness of video content, and effectively meeting the diverse audio recording needs of users in complex scenarios.

[0149] In one exemplary embodiment, the video recording method further includes:

[0150] Based on a first preset ratio, audio bandwidth is allocated to other audio devices and shooting devices in the multi-audio device network, in order to acquire and send audio data to the shooting devices.

[0151] Audio bandwidth refers to the communication capability of an audio device when transmitting audio data, similar to the width of a road. A larger bandwidth means more audio data can be transmitted per unit time, supporting higher quality and richer audio content. For example, high bandwidth allows audio data to contain more detail and a wider frequency range, making the sound clearer and fuller. The first preset ratio refers to a pre-set ratio used to allocate the audio bandwidth of the audio device to the shooting device and other audio devices in a multi-audio device network. This ratio allows for reasonable coordination of audio data transmission between the audio device, the shooting device, and other audio devices, ensuring that each device receives sufficient bandwidth to complete audio acquisition, transmission, and processing operations.

[0152] For example, in a single-chip Bluetooth audio device, since it typically has only one chip handling Bluetooth communication and audio encoding / decoding, its audio bandwidth is relatively limited because the processing and communication capabilities of a single chip have certain limits. For instance, it may only support audio data transmission at a fixed sampling rate and encoding format. A common single-chip Bluetooth audio device might only support enough audio bandwidth for ordinary music playback or everyday calls. Assuming the total audio bandwidth of this single-chip Bluetooth audio device is 100 units (this unit is assumed for ease of understanding; in practice, it might be measured in bit rate, etc.), and the first preset ratio is set to allocate 70% to the shooting device and 30% to other audio devices in a multi-audio device network, then during audio data transmission, 70 units of bandwidth will be used to transmit audio to the shooting device to ensure that the shooting device can receive the audio data collected by this audio device; the remaining 30 units of bandwidth will be used for audio interaction with other audio devices, enabling audio transmission and sharing among multiple audio devices. For dual-chip Bluetooth audio devices, the enhanced processing and communication capabilities compared to single-chip devices, due to the presence of two chips, result in a larger audio bandwidth. These two chips can work independently or collaboratively, supporting higher sampling rates and more complex encoding formats, thus transmitting more audio data. For example, a dual-chip Bluetooth audio device can simultaneously handle high-definition audio recording and transmission, as well as stable audio communication with multiple devices. Assuming the total audio bandwidth of the dual-chip Bluetooth audio device is 200 units (increased due to stronger processing power), and the initial preset ratio is set to 50% allocated to the shooting device and 50% to other audio devices, then 100 units of bandwidth will be used to transmit audio to the shooting device (equivalent to one chip transmitting audio to the shooting device), providing richer and higher-quality audio data; 100 units of bandwidth will be used for audio interaction with other audio devices (equivalent to another chip transmitting audio to the shooting device), making audio transmission between multiple audio devices smoother and better enabling the synchronous acquisition and transmission of audio content from multiple users using at least two audio devices.

[0153] In this embodiment, by allocating bandwidth according to a first preset ratio, resources can be rationally planned based on the hardware characteristics of the audio devices (such as the difference in processing power between single-chip and dual-chip devices). This ensures that the shooting device has sufficient bandwidth to acquire high-quality and complete audio information when receiving audio data from a single audio device, avoiding audio loss or quality degradation due to insufficient bandwidth. Simultaneously, the bandwidth allocated for interaction between the audio device and other audio devices within the network ensures stable transmission of audio data between multiple audio devices, enabling the shooting device to ultimately receive audio data that fully covers the audio content collected by at least two audio devices from multiple users. Furthermore, this bandwidth allocation mechanism optimizes data transmission efficiency, reduces transmission conflicts and latency, and improves audio and video synchronization. This helps the shooting device efficiently acquire and generate high-quality audio and video containing rich audio content collected by at least two audio devices, better meeting the shooting needs in multi-user interactive scenarios.

[0154] In one exemplary embodiment, such as Figure 8 As shown, when the audio device is also connected to a mobile terminal, the method further includes:

[0155] If audio is being transmitted to the first device and audio needs to be transmitted to the second device, and if the third preset condition is met, a first notification message is sent to the shooting device.

[0156] The first device is one of the shooting device and the mobile terminal, the second device is the other of the shooting device and the mobile terminal, and the third preset condition is that the priority of audio transmission between the audio device and the mobile terminal is higher than the priority of audio transmission between the audio device and the shooting device.

[0157] The first notification message is a message generated and sent by the audio device under preset conditions. When the audio device is currently transmitting audio to the first device and also needs to transmit audio to the second device, and a third preset condition is met, the audio device generates this first notification message to inform the relevant device (such as the camera device) that it needs to perform corresponding operations (such as activating the camera device's microphone). The third preset condition refers to the priority of audio transmission between the audio device and the mobile terminal being higher than the priority of audio transmission between the audio device and the camera device, used to determine whether a switching of audio recording methods is necessary. Specifically, when the first device is the camera device and the second device is the mobile terminal: the audio device is currently transmitting audio to the camera device. When a mobile terminal needs to transmit audio to the audio device, and the third preset condition of higher priority for mobile terminal audio transmission is met, the audio device generates the first notification message. This first notification message informs the camera device that because the audio device must prioritize the mobile terminal's audio transmission needs, the camera device needs to take corresponding measures (activate its own microphone). This means that in this scenario, the mobile terminal's audio transmission needs have higher priority. For example, when a mobile terminal receives an urgent voice call or important voice command, the audio device needs to prioritize its service, while the audio transmission needs of the shooting device are secondary. When the first device is a mobile terminal and the second device is a shooting device: the audio device initially transmits audio to the mobile terminal. When the shooting device also needs to transmit audio to the audio device, if the third preset condition that the mobile terminal's audio transmission priority is higher than the shooting device's is met, the audio device will also generate a first notification message. However, this first notification message is mainly to inform the shooting device that its audio transmission priority is lower, and it may need to turn on its microphone to record sound to ensure normal audio acquisition. Again, it emphasizes that the mobile terminal's audio transmission priority is higher than the shooting device's. For example, if the mobile terminal is conducting a real-time voice broadcast, the requirements for audio real-time performance and stability are very high, while the shooting device's audio acquisition needs are relatively less urgent. Therefore, the audio device prioritizes the mobile terminal's audio transmission, and the shooting device needs to make corresponding adjustments based on the first notification message.

[0158] For example, the audio device in this embodiment is as follows: Figure 7Taking audio device C in a multi-audio device network as an example in the illustrated application scenario, audio device C is not only connected to the shooting device but also interacts with other audio devices in the multi-audio device network, exchanging audio data. When an audio device is currently transmitting audio to the shooting device and simultaneously needs to transmit audio to a mobile terminal, and the third preset condition is met (the mobile terminal's audio transmission priority is higher than the shooting device's), the audio device generates a first notification message. This is because the mobile terminal may have needs such as urgent voice calls or important voice commands, which have a higher priority. The audio device sends the first notification message to the shooting device, informing it that it needs to switch its audio recording mode. After receiving the first notification message, the shooting device activates its own microphone to record audio. This breaks the situation where the shooting device always occupies the audio channel of the audio device, allowing the shooting device to continue audio acquisition through its own microphone without affecting the audio device's service to the mobile terminal, thus meeting the mobile terminal's needs. Meanwhile, the audio interaction between other audio devices in the multi-audio device network is not affected, and the shooting device can also obtain the audio data collected by its own microphone, ensuring the integrity of the audio during video recording and achieving good compatibility between the shooting device, audio device, mobile terminal, and multi-audio device network.

[0159] In this embodiment, by setting up an audio device notification and priority judgment mechanism, the compatibility of the shooting device in multi-device collaborative scenarios is significantly improved. When the audio device is connected to the mobile terminal and a higher-priority audio request occurs, the shooting device can promptly receive the first notification information sent by the audio device and actively switch to its own microphone for sound pickup, breaking the limitation of the traditional shooting device always occupying the audio channel of the audio device. This allows the shooting device to both proactively yield when the mobile terminal needs to use the audio device first, avoiding conflicts caused by audio resource contention between devices, and ensure that its own video recording audio acquisition is not affected, continuously acquiring stable audio data. Regardless of the complexity of the multi-device connection environment, the shooting device can flexibly adapt and achieve good compatibility with mobile terminals, audio devices, and other devices, effectively ensuring the integrity and coordination of audio and video during video creation, and meeting users' needs for high-quality audio and video acquisition in diverse scenarios.

[0160] In one exemplary embodiment, a video recording method is provided, applied to an audio terminal, wherein when the audio device is connected to a mobile terminal and the mobile terminal, the method includes:

[0161] If audio is being transmitted to the first device and audio needs to be transmitted to the second device, and if the third preset condition is met, a first notification message is sent to the shooting device.

[0162] The first device is one of the shooting device and the mobile terminal, the second device is the other of the shooting device and the mobile terminal, and the third preset condition is that the priority of audio transmission between the audio device and the mobile terminal is higher than the priority of audio transmission between the audio device and the shooting device.

[0163] The meaning and explanation of the first notification information and the third preset ratio can be found in the description in the foregoing embodiments, and will not be repeated here.

[0164] For example, as Figure 9 The illustrated application scenario uses an audio device C connected only to a mobile terminal and a camera as an example. When the audio device is only connected to the camera and the mobile terminal, if the audio device is currently transmitting audio to the camera, but the mobile terminal has a higher priority audio transmission requirement (such as a task requiring high real-time performance and stability, like live audio streaming), the audio device generates a first notification message and sends it to the camera. Upon receiving the notification, the camera activates its own microphone and no longer occupies the audio channel of the audio device, allowing the audio device to prioritize the mobile terminal's audio transmission needs. Conversely, if the audio device is initially transmitting audio to the mobile terminal, and the camera needs audio transmission but the mobile terminal has a higher priority, the audio device also sends a first notification message to the camera, prompting the camera to activate its microphone for audio capture. In this way, the camera no longer constantly occupies the audio channel of the audio device but can flexibly switch the recording method based on the first notification message. When the audio device is connected to the mobile terminal, it effectively accommodates the mobile terminal's needs, ensuring the smooth operation of the mobile terminal's audio tasks, while the camera can continue to capture audio using its own microphone, guaranteeing effective audio acquisition during video recording.

[0165] It should be noted that, for applications Figure 8 The hardware architecture shown or Figure 9 The video recording method for the audio device under the hardware architecture shown in the application also provides at least the following embodiments:

[0166] In one exemplary embodiment, the method further includes:

[0167] S701, when the audio device is currently transmitting audio to the shooting device, and it is necessary to transmit audio to the mobile terminal, a first notification message is sent to the shooting device. The first notification message is used to instruct the mobile terminal to transmit audio to the audio device.

[0168] When the audio device is in a state of transmitting audio to both the shooting device and the mobile terminal, the first notification message sent by the audio device has an indicative function. It mainly conveys to the shooting device that the mobile terminal has a need to use the audio channel of the audio device and needs to occupy the channel first for audio transmission.

[0169] For example, in the current device connectivity and audio transmission scenario, the allocation of audio channel resources on the audio device changes due to the audio transmission needs of the mobile terminal. As one of the devices connected to the audio device, the shooting device, upon receiving the first notification information, is aware that its priority in audio transmission may have changed and needs to adjust its recording settings accordingly. For instance, the shooting device might initially be using the audio device's microphone, but when the mobile terminal has urgent voice calls or important voice commands requiring high real-time audio performance and stability, the audio device needs to prioritize allocating audio channel resources to the mobile terminal to meet its needs. In this case, the first notification information informs the shooting device that it can no longer use the audio device's microphone for recording, and the shooting device may need to activate its own microphone to continue audio acquisition to adapt to this change in audio channel resource allocation.

[0170] In this embodiment, through the above method, the first notification information establishes an effective information transmission mechanism between the audio device, the shooting device, and the mobile terminal, enabling the shooting device to flexibly adjust its working mode according to the actual situation of audio transmission between devices. In this way, in the complex audio transmission scenario with multiple device connections, it ensures that each device can use audio channel resources relatively reasonably and meet the audio transmission needs of different devices.

[0171] In one exemplary embodiment, the video recording method further includes:

[0172] If audio is being transmitted to the first device but not to the second device, or if the target conditions are not met, stop sending the first notification message to the shooting device.

[0173] Among them, the target condition is not met, that is, the priority of audio transmission between audio devices and mobile terminals is lower than or equal to the priority of audio transmission between audio devices and shooting devices.

[0174] For example, when the audio device is transmitting audio to the shooting device (first device), if it does not need to transmit audio to the mobile terminal (second device), it means that the audio channel resources of the audio device are not occupied by the audio needs of other devices. In this case, the audio device can concentrate all its audio transmission capabilities on serving the shooting device, allowing the shooting device to successfully record sound through the audio device's microphone. Because there are no other devices' audio transmission tasks interfering with the audio transmission link between the audio device and the shooting device, the audio device's microphone can focus on collecting sound and stably transmitting the audio data to the shooting device. Therefore, there is no need to send a first notification message to inform the shooting device that it needs to switch the recording mode, ensuring the normal recording of sound by the shooting device and meeting the audio requirements of video recording. When the priority of audio transmission between the audio device and the mobile terminal is equal to the priority of audio transmission between the audio device and the shooting device, although the mobile terminal may have audio transmission needs, since its priority is the same as the shooting device, there is no situation where the audio device needs to prioritize serving the mobile terminal and abandon audio transmission for the shooting device. The audio device does not need to interrupt or change its audio transmission to the other party to satisfy one party. Therefore, there is no need to send an initial notification to the camera to switch audio recording modes. The audio device can continue audio transmission with the camera, allowing the camera to record audio through its microphone. This ensures the stability of the camera's audio acquisition process, preventing unnecessary switching of recording modes due to priority conflicts. This allows the camera to continuously and stably acquire audio data from the audio device's microphone for video recording. When the priority of audio transmission between the audio device and the mobile terminal is lower than that between the audio device and the camera, the audio device will prioritize audio transmission with the camera. The audio channel resources of the audio device will be preferentially allocated to the camera to meet its audio acquisition needs. Therefore, there is no need to send an initial notification to the camera to switch audio recording modes. The camera can record audio through the audio device's microphone, and this recording method will not be interfered with by the mobile terminal's audio transmission needs. The audio device uses its primary audio transmission capabilities for interaction with the camera, ensuring that the camera can acquire high-quality audio data, thereby guaranteeing the integrity and quality of the audio portion in video recording.

[0175] In this embodiment, when the audio device is transmitting audio with the first device (the shooting device) and does not need to transmit audio with the second device (the mobile terminal), or when the target condition of the mobile terminal's audio transmission priority being higher than that of the shooting device is not met, the first notification information to be sent to the shooting device is stopped, avoiding unnecessary information interaction. This allows the audio device to focus on the current audio transmission task with the shooting device, devoting all its audio transmission capabilities to it to ensure stable audio data transmission. When priorities are equal or the mobile terminal has a lower priority, the audio device does not need to perform complex operations or interrupt existing transmissions to adjust audio transmission, maintaining the stability of audio transmission with the shooting device, reducing the consumption of processing resources, improving audio transmission efficiency, and ensuring that the shooting device can continuously and stably acquire high-quality audio data, thereby providing reliable audio support for video recording. This achieves optimized management of audio transmission by the audio device in multi-device connection scenarios.

[0176] In one exemplary embodiment, the video recording method further includes:

[0177] S704: When the mobile terminal stops transmitting audio to the audio device, and the audio device needs to transmit audio to the shooting device, a second notification message is sent to the shooting device.

[0178] For example, during operation, once the mobile terminal stops audio transmission with the audio device (e.g., the mobile terminal ends a voice call, closes an application playing audio, or terminates a live audio broadcast), the status monitoring module inside the audio device will detect this change. Simultaneously, if the audio device still needs to transmit audio to the camera (e.g., the camera is recording video and needs to continuously receive sound from the audio device), the audio device's control unit will trigger an information generation mechanism to generate a second notification message according to a preset communication protocol and data format. This notification message contains key information about the mobile terminal stopping audio transmission and its need to transmit audio to the camera. Subsequently, the audio device sends the second notification message to the camera via a pre-established communication link such as Bluetooth or Wi-Fi.

[0179] In this embodiment, the audio device can flexibly and proactively transmit key information according to changes in the audio transmission needs of different devices, effectively coordinating the relationship with the mobile terminal and the shooting device, and avoiding audio transmission chaos caused by changes in the status of devices. For the shooting device, by receiving the second notification information, it can promptly perceive changes in the status of external devices, thereby quickly adjusting its own audio reception strategy to ensure that it can continue to stably acquire audio data transmitted by the audio device even after the mobile terminal's audio transmission stops, ensuring the continuity of audio acquisition during video recording and avoiding audio interruptions or loss.

[0180] In one exemplary embodiment, the audio device is also used to connect to a mobile terminal, and the method further includes:

[0181] When transmitting audio to the shooting device and also to the mobile terminal, the audio bandwidth is allocated to the mobile terminal and the shooting device based on a second preset ratio.

[0182] Audio bandwidth refers to the communication capability of an audio device when transmitting audio data. A larger bandwidth means more audio data can be transmitted per unit time, which translates to supporting higher quality and richer audio content transmission. For example, high bandwidth allows audio data to contain more detail and a wider frequency range, making the sound clearer and fuller. The second preset ratio refers to a pre-set proportional value used to allocate the audio bandwidth of the audio device to the shooting device and other audio devices in a multi-audio device network. This ratio allows for reasonable coordination of audio data transmission between the audio device, the shooting device, and other audio devices, ensuring that each device receives sufficient bandwidth to complete audio acquisition, transmission, and processing operations.

[0183] For example, in a single-chip Bluetooth audio device, since it typically has only one chip handling Bluetooth communication and audio encoding / decoding, its audio bandwidth is relatively limited because the processing and communication capabilities of a single chip have certain limits. For instance, it may only support audio data transmission at a fixed sampling rate and encoding format. A common single-chip Bluetooth audio device might only support enough audio bandwidth for ordinary music playback or everyday calls. Assuming the total audio bandwidth of this single-chip Bluetooth audio device is 100 units (this unit is assumed for ease of understanding; in practice, it might be measured in bit rate, etc.), and the second preset ratio is set to 70% allocated to the shooting device and 30% to the mobile terminal, then during audio data transmission, 70 units of bandwidth will be used to transmit audio to the shooting device to ensure that the shooting device can receive the audio data captured by the audio device; the remaining 30 units of bandwidth will be used for audio interaction with the mobile terminal. In contrast, a dual-chip Bluetooth audio device, equipped with two chips, has enhanced processing and communication capabilities compared to a single-chip Bluetooth audio device, resulting in a larger audio bandwidth. These two chips can work independently or collaboratively, supporting higher sampling rates and more complex encoding formats, thus transmitting more audio data. For example, a dual-chip Bluetooth audio device can simultaneously handle high-definition audio recording and transmission, as well as stable audio communication with multiple devices. Assuming the total audio bandwidth of the dual-chip Bluetooth audio device is 200 units (bandwidth increases due to stronger processing capabilities), and the second preset ratio is set to allocate 50% to the shooting device and 50% to other audio devices, then 100 units of bandwidth will be used to transmit audio to the shooting device (equivalent to one chip transmitting audio to the shooting device), providing the shooting device with richer and higher-quality audio data; 100 units of bandwidth will be used for audio interaction with the mobile terminal (equivalent to another chip transmitting audio to the mobile terminal), making audio transmission with the mobile terminal smoother. This allocation method allows for more flexible optimization of audio transmission according to the needs of different devices, ensuring audio quality for the mobile terminal while also meeting the basic audio requirements of the shooting device.

[0184] In this embodiment, by allocating audio bandwidth to the mobile terminal and the shooting device based on a second preset ratio, audio transmission between different devices can be flexibly and reasonably coordinated. Whether it's a single-chip or dual-chip Bluetooth audio device, it can, based on its own audio bandwidth characteristics and the second preset ratio, meet the audio acquisition needs of the shooting device while also considering the audio interaction of the mobile terminal. This ensures that each device receives sufficient bandwidth to achieve stable, high-quality audio transmission, effectively improving the adaptability and performance of the audio device in multi-device audio transmission scenarios and optimizing the overall audio experience.

[0185] In one exemplary embodiment, this embodiment also provides a video recording system, which includes a shooting device and an audio device connected to each other, wherein,

[0186] The audio device is used to send audio data to the shooting device during the video recording process when the audio device is one of the audio devices in a multi-audio device network. The audio data includes audio content collected by at least two audio devices in the multi-audio device network.

[0187] The camera is used to receive audio data sent by the audio device; and generates audio and video files based on the audio data and the video recorded by the camera.

[0188] In one embodiment, the camera is further configured to split the audio data into multiple audio tracks according to a preset audio data processing rule; perform speaker matching based on the multiple audio tracks, and include speaker information in the corresponding audio and video frame.

[0189] In one embodiment, the audio device is further configured to allocate audio bandwidth to the multi-audio device network and the shooting device based on a first preset ratio, so as to acquire and send audio data to the shooting device;

[0190] The shooting device is also used to allocate audio bandwidth to the multi-audio device network and the shooting device according to the audio device based on a first preset ratio, and to receive audio data sent by the audio device.

[0191] In one embodiment, the camera device is also used to record sound through the camera device microphone when a first preset condition is met.

[0192] In one embodiment, the shooting device is further configured to, when a second preset condition is met, stop the shooting device microphone from recording sound and receive audio transmitted by the audio device microphone.

[0193] In an exemplary embodiment, when the audio device is also connected to a mobile terminal, the first preset condition includes: receiving a first notification message sent by the audio device, the first notification message being used to instruct the audio device to transmit audio to the mobile terminal; or, receiving a first user operation, the first user operation being used to instruct the microphone of the shooting device to be turned on.

[0194] The audio device is also used to send a first notification message to the shooting device if a third preset condition is met when the audio is currently being transmitted to the first device and audio needs to be transmitted to the second device.

[0195] Among them, the first device is one of the shooting device and the mobile terminal, the second device is the other of the shooting device and the mobile terminal, and the third preset condition includes that the priority of audio transmission between the audio device and the mobile terminal is higher than the priority of audio transmission between the audio device and the shooting device.

[0196] The shooting device is also used to receive a first notification message sent by an audio device, or to record sound through the microphone of the shooting device when it receives a first user operation.

[0197] In an exemplary embodiment, the audio device is further configured to send a first notification message to the shooting device when the audio device is currently transmitting audio to the shooting device and needs to transmit audio to the mobile terminal. The first notification message is used to indicate that the mobile terminal needs to transmit audio to the audio device.

[0198] In an exemplary embodiment, when the audio device is also connected to a mobile terminal, the second preset condition includes: receiving a second notification message sent by the audio device, the second notification message being used to instruct the audio device to transmit audio to the shooting device; or, receiving a second user operation, the second user operation being used to instruct the microphone of the shooting device to be turned off.

[0199] The audio device is also used to send a second notification message to the camera device when the mobile terminal stops transmitting audio to the audio device and the audio device needs to transmit audio to the camera device.

[0200] The camera device is also used to stop its microphone from picking up sound and receive audio from the audio device's microphone when it receives a first notification message from the audio device or a second user operation.

[0201] In an exemplary embodiment, when the shooting device is a dual-track audio recording device, the first audio track is configured as a silent frame, and the second audio track is configured to record audio from the microphone of the shooting device; wherein, the first audio track is an audio track for recording audio from the microphone of the audio device, and the second audio track is an audio track for recording audio from the microphone of the shooting device.
