[0032] In order to solve the problem in the prior art that the signal in some areas is relatively poor, if the first-party media application currently being played is broadcast by the radio, the playback may be interrupted or stuck due to the signal problem, thereby reducing the driver's experience; in addition, the driver is easily distracted when switching between media applications, which may easily cause driving safety hazards; an embodiment of the present invention provides a method for switching multimedia playback.

[0033] The method of the embodiment of the present invention uses a controller of the vehicle, the controller establishes a remote communication connection with a cloud server, and the controller is controlled and connected with a player and a receiver arranged in the vehicle.

[0034] Specifically, the controller is the control system of the entire vehicle. It is used to receive data input by various sensors, process the data according to preset algorithms and logic, and then output instructions to control various functions of the vehicle. More specifically, the controller is composed of the electronic control unit (ECU), actuator and vehicle control unit (VCU). Among them, the sensor is used to collect the voice emitted by the driver, such as the voice receiver, and convert the parameter into an electrical signal and transmit it to the electronic control unit. The electronic control unit analyzes, processes and calculates the received electrical signal, and finally generates the corresponding control instruction and sends it to the actuator. The actuator controls the corresponding components of the vehicle accurately according to the received control instruction.

[0035] The following describes in detail the specific steps of a method for switching multimedia playback provided by an embodiment of the present invention. Figure 1-2 As shown in , the method for switching multimedia playback specifically includes the following steps:

[0036] Step S110, continuously acquiring the signal received by the receiver.

[0037] Specifically, the signal is transmitted via a satellite, which is in geosynchronous orbit and can broadcast powerful signals to the ground. Such signals include audio, video and other data, which are sent in the form of radio waves. The satellite signal can be captured by the receiving device on the vehicle. Since the receiving device has a receiving antenna and a receiver chip, it can capture and decode signals from the satellite. After the vehicle's receiving device receives the signal from the satellite through its built-in antenna, it is amplified and converted into digital data in the receiver chip. Subsequently, the digital data is decoded through the device's internal processing circuit to extract audio, video or other data. With this setting, the vehicle needs to maintain a communication connection between the receiving device and the satellite during driving to achieve continuous signal reception.

[0038] It is understood that the receiving device of the embodiment of the present invention is a frequency modulation (FM) receiver, which is used to send high-fidelity audio, so that a variable carrier frequency carries the sound signal, and the receiver is used to receive high-quality audio broadcasts such as music stations and traffic information. Or, the receiving device is an amplitude modulation (AM) receiver: the AM system uses a carrier waveform with a variable amplitude at a fixed frequency to transmit the sound signal. The specific type of the receiving device is not limited here.

[0039] Step S120, detecting whether the strength value of the signal meets a preset strength index value.

[0040] Specifically, since the receiver may be affected by many factors during the process of receiving the signal, such as multipath effect, interference, etc., it is necessary to properly process and amplify the signal, demodulate the captured signal to extract the information (such as audio, data, etc.), and then measure the signal strength by using radio signal measuring instruments (such as antenna testers, signal analyzers, etc.). The signal strength is usually expressed in decibels (dB), which reflects the power of the signal. The received signal strength is compared with the preset signal strength threshold, which can be set according to the application scenario and requirements, such as ensuring audio quality, data transmission rate, etc.

[0041] If the measured signal strength meets or exceeds the preset threshold, it is considered that the signal strength is sufficient and does not affect the playback of the first-party media application. If the signal strength is insufficient, it may affect the playback of the first-party media application.

[0042] In the above-mentioned embodiment, the method of detecting whether the strength value of the signal meets the preset strength index value specifically includes the following:

[0043] Calculate the absolute comparison. If the signal strength value (e.g., dBm) is greater than or equal to the preset strength index value (e.g., -70dBm), the signal strength value meets the requirement; otherwise, if the measured value is less than the preset threshold value (e.g., -75dBm), the requirement is not met.

[0044] Calculate the relative comparison, if the signal strength value is between the lower limit (e.g., -70dBm) and the upper limit (e.g., -50dBm) of the preset strength index value, then the requirement is met. If the signal strength value is lower than the set lower limit or higher than the set upper limit, then the requirement is not met.

[0045] Step S130: if the preset strength index value is not met, detecting whether a request for switching to a third-party media application to play is received; if a request for switching to a third-party media application to play is received, switching to the corresponding third-party media application for playing according to the play request.

[0046] Specifically, when the vehicle is driving in an area with poor signals, such as when the vehicle is driving in a tunnel, this area is likely to affect signal transmission; when the signal strength value does not meet the strength index value, since the signal strength at this time cannot continuously support the playback of the first-party media application, in order to avoid affecting the driver's experience, a request is sent to the driver whether to switch to a third-party media application for playback. Specifically, a prompt message is displayed on the screen to inform the user that the current signal is weak or cannot be received. At the same time, an option may be provided on the interface for the user to choose whether to switch to a third-party media application for playback, or to inform the driver through a voice prompt. Therefore, it can be achieved through a graphical interface or voice interaction. If the driver agrees to switch the playback of the third-party media application, a request to switch the playback of the third-party media application can be issued. At this time, the controller will parse the received playback request instruction. When the playback requirements of the third-party media application are clear, if it is necessary to obtain new content or streaming media services from an external network such as the Internet, a request is made to establish a network connection through the vehicle's own navigation system. Once the specific content of the playback request is determined, the corresponding media content is obtained through the vehicle's internal or external network connection. After the vehicle's receiver receives the media stream returned by the third-party network media provider, it passes it to the vehicle's audio / video receiver (for example, a built-in audio system or display screen), then decodes the audio / video, and starts playing the third-party media application, thus completing the switch to the corresponding third-party media application for playback according to the playback request.

[0047] It can be understood that the third-party media application of the embodiment of the present invention includes a specific online music, online video or online radio (if the currently playing content is already included in the audio stream in the built-in database, it will automatically take over the processing); the first-party media application of the embodiment of the present invention is the broadcast played by the radio.

[0048] Step S140: If the preset strength index value is met, detecting whether a request to resume playing the first-party media application is received.

[0049] Specifically, when the signal is weak and when a playback request to switch to a third-party media application is received, the third-party media application is switched and played continuously; since the signal received by the receiver is continuously obtained, if the received signal is strong or the normal signal is restored, in order to restore the playback of the original first-party media application, a prompt is issued to the driver whether to restore the first media playback, such as displaying whether to restore the first media playback on the display screen or informing the driver by voice whether to restore the first media playback; it can be seen that after the detection signal is restored to the point where the first-party media application can be listened to, the controller detects whether a request to restore the playback of the first media issued by the driver is received, for example, by displaying a screen, voice recognition, etc.

[0050] Step S150: if a request to resume playing the first-party media application is received, switching back to the first-party media application for playing.

[0051] Specifically, once a request to resume playback of a first-party media application is detected by the driver, the controller pauses or stops (depending on the instant playback status) the playback content of the third-party media application currently being played to facilitate switching. Subsequently, the receiver begins to re-receive the signal for playing the first-party media application and prioritizes the received signals according to preset signal quality standards (for example, sound quality, signal coverage, and radio station type, etc.). Once the best signal with quality that meets the requirements is determined and selected, the controller continues to play the content of the first-party media application corresponding to the signal.

[0052] It should be noted that if it is necessary to restore the frequency band or channel of the first-party media application that has received the signal, the controller activates the built-in tuner, tunes the tuner according to the previously saved broadcast frequency or the driver's newly selected frequency, and then plays it.

[0053] Step S160: If no request to resume playing of the first-party media application is received, the third-party media application continues to play.

[0054] Specifically, once the controller detects a playback request from the driver to resume the playback of the first-party media application, the controller will parse and process the request signal. Conversely, if the controller does not detect a playback request from the driver, the controller continues to play the current third-party network media content according to a preset logic, and then continues to connect to the third-party media application through a corresponding data communication protocol to obtain the playback content of the third-party media application and play it. In this way, the controller continuously detects whether a playback request from the driver is received, so that it can quickly respond and switch when a playback request to resume the first-party media application is received.

[0055] To sum up the above, when the signal strength value does not meet the preset strength index value, it is detected whether a playback request to switch to a third-party media application is received; if a playback request to switch to a third-party media application is received, it is switched to the corresponding third-party media application for playback according to the playback request; when the signal strength value meets the preset strength index value, it is detected whether a playback request to restore the first-party media application is received, and it is switched back to the first-party media application for playback or continues to be played by the third-party media application according to the playback request. Automatically switching media applications can reduce the number of manual operations performed by the driver during driving, which is beneficial to improving driving safety. In some areas with poor signals, it can also improve the driving experience by switching to a third-party media application.

[0056] In some specific embodiments, switching to a corresponding third-party media application according to the playback request in step S130 specifically includes the following steps:

[0057] Parse the playback request to get the target type.

[0058] Specifically, the controller receives a playback request from the driver, which can be performed through touch operation, button operation or voice command. If it is a touch or button operation, the controller identifies the instruction corresponding to the operation. If it is a voice command, the controller identifies it through voice recognition technology and converts it into a corresponding instruction. The instruction is used to obtain the type of the specified third-party media application. Finally, the parsed instruction will be sent to the in-vehicle multimedia system, and the controller will then perform corresponding operations based on the instruction.

[0059] Get the third-party media application corresponding to the target type from the database.

[0060] Specifically, since the database is used to store information about various media applications, the application information includes the name, type, function description, developer information, etc. of the application. The table structure in the database will be designed accordingly for such information. The information of third-party media applications collected through API or other channels will be stored in the database. This process involves data input, storage and management. When the driver issues a playback request (such as looking for video playback applications), the target type is identified, such as through keyword analysis input by the user or intelligent analysis of the system (such as inferring the needs of the driver based on the user's historical behavior). According to the identified target type, the controller sends a query request to the database to find matching application information. The query can be a simple keyword-based search or a complex combination query based on multiple conditions, which is handled by the database management system (DBMS).

[0061] It should be noted that when a third-party media application communicates with a database, an API (application programming interface) may be used, and the API provides a clear method to send a request to the database. In this process, the API is used to return a list of applications of a specific type.

[0062] Switch to a third-party media app and control the player to play.

[0063] Specifically, after obtaining the target type of third-party media application information, the controller sends a control signal to the player to trigger the player to play; specifically, once the third-party media application is started, the controller needs to control the player's functions through the corresponding application program interface (API), and the API allows the vehicle system to communicate and exchange data with the third-party media application. Through the API, the vehicle system sends control instructions to the player of the third-party media application, and decodes and processes them locally, so that the player can perform corresponding functions according to the control instructions, such as playing music, videos, and online radio.

[0064] In a further embodiment, before controlling the player to switch to the third-party media application for playback, the following steps are also included:

[0065] Get a variety of pre-built media data from third-party media applications.

[0066] Specifically, since the third-party media application stores the preset communication media data in a specific data structure, such as a sub-database or a file system, the controller can access and obtain the corresponding communication media data through the corresponding API. It can be understood that the communication media data is song data, online broadcast data or video data, etc.

[0067] In the above embodiment, the processed data is returned to the controller via an HTTP response. The response includes a status code (such as 200 for success, 404 for not found, etc.), a data body, and possible metadata (such as content type, cache control, etc.). After receiving the response, the controller needs to parse the returned data to extract the required information, for example, parsing JSON or XML data, processing binary files, or reading data directly from the file system. Finally, the data is used to control the player to play.

[0068] It should be noted that after obtaining the corresponding media data from a third-party media application, the media data needs to be parsed and processed for subsequent use, which includes identifying and extracting metadata in the data (such as song data, online radio data or video data), as well as supporting the format of the data file.

[0069] All pre-identified communication media data are obtained from multiple communication media data.

[0070] Specifically, among multiple communication media data, each communication media data usually has only one unique identifier (such as ID, URL, etc.). At the same time, the system will send a query request to the database for each pre-identified communication media data when the controller needs to obtain all the identified communication media data. The request contains specific query conditions, instructing the database to return all identified records. After receiving the query request, the database will perform a retrieval operation according to the preset query conditions. The database will search for records of all identified communication media data, which contain basic information of the communication media data and detailed information of the collection user. Once the database finds a matching result, it returns the matching result to the controller that sent the query request.

[0071] All identified communication media data are used as playback objects for third-party media applications.

[0072] Specifically, after receiving the result returned by the database, the controller will perform further data processing and application, and finally use all the identified communication media data as the playback object of the third-party media application, that is, the playback identified communication media data.

[0073] In the above embodiment, after all pre-identified communication media data are obtained from the multiple communication media data, the following steps are also included:

[0074] Upload all pre-labeled communication media data to the cloud server for storage.

[0075] Specifically, the cloud server is a technology used to provide data storage services through the Internet, allowing different accounts to access and share data through the network, thereby avoiding data loss or system failure. Therefore, all the identified communication media data can be uploaded to the cloud server, specifically, using a transmission protocol such as HTTP or HTTPS, so that the encoded and compressed communication media data is uploaded to the cloud server, and finally each communication media data is stored in an object storage system, so that the driver can access the object storage system of the cloud server through the Internet at any time and any place, and download the selected communication media data to play locally, or directly play it online.

[0076] It should be noted that drivers need to log in to their accounts to access their object storage systems, and the cloud server needs to verify the driver's identity and authorize the user to access the corresponding permissions.

[0077] In some specific embodiments, the step is before switching to the corresponding third-party media application for playback according to the playback request or before continuing to be played by the third-party media application, and further includes the following steps:

[0078] Check whether the remaining flow exceeds the preset flow threshold.

[0079] Specifically, in order to prevent excessive traffic from being used when switching to a third-party media application for playback, the driver can set a preset traffic threshold in the vehicle's control system to allow the maximum traffic value to be used before switching to the corresponding third-party media application for playback according to a playback request or before continuing to play the third-party media application.

[0080] For example, before the playback request is switched to the corresponding third-party media application for playback, it is detected whether the remaining traffic is sufficient for the third-party media application to be switched to play; before the third-party media application continues to play, it is detected whether the remaining total traffic is sufficient for the continued use of the third-party media application to play.

[0081] If the preset flow threshold is exceeded, the driver will be prompted.

[0082] Specifically, if it is detected that the used traffic is about to exceed the traffic threshold, the user can be reminded of the remaining traffic through the vehicle's display screen, voice prompts or SMS notifications.

[0083] In some cases, background data usage of a third-party media application can be automatically restricted according to a preset traffic policy, or data transmission of the third-party media application can be automatically suspended when traffic is insufficient.

[0084] In one specific embodiment, if the preset strength index value is not met, the system further includes sending a request to the driver whether to switch the playback of the third-party media application. In another specific embodiment, if the preset strength index value is met, the system further includes sending a request to the driver whether to restore the playback of the first-party media application.

[0085] Specifically, once a weak signal is detected, a request to switch to a third-party media application will be sent to the driver through the vehicle system. The request can be in the form of sound prompts, vibration feedback, or screen display. The specific method depends on the design of the vehicle system and the needs of the driver, and is not limited here. This setting effectively improves driving safety, optimizes driving experience, and increases human-computer interaction.
