Description

Technical Field

[0001] The present application relates to the field of audio control technology, and in particular to a method and device for controlling multimedia audio on a single screen. Background Art

[0002] Vehicles equipped with a passenger / rear screen now have the ability to independently control and play multimedia audio based on screen location. For example, the driver can play music on the driver's center console, while the passenger in the passenger / rear seat can use headphones to watch a video on the passenger / rear seat screen, independently and without interference.

[0003] However, most current models only have a single central control screen, preventing the driver and front passenger from independently controlling and playing multimedia sources. For example, if the driver is listening to music A and the front passenger opens video B, the music will be interrupted. Only one multimedia source can be played at a time, affecting the user experience. Summary of the Invention

[0004] The main purpose of this application is to provide a single-screen multimedia audio control method and device, aiming to solve the technical problem that the current single screen can only play one multimedia audio source at the same time, and the driver and co-driver cannot independently control and play the multimedia audio source.

[0005] To achieve the above objectives, the present application proposes a single-screen multimedia audio control method, which includes:

[0021] When the first sound source exists in the target sound zone sound source list, the first sound source is played through the playback device in the target playback sound zone.

[0022] Before the step of determining the target sound zone sound source list according to the target playback sound zone, the method further includes:

[0023] Providing a multimedia audio source configuration interface so that the user can configure the audio source on the multimedia audio source configuration interface;

[0024] Upon receiving a sound source configuration instruction from a user based on the multimedia sound source configuration interface, traversing a multimedia application list according to the sound source configuration instruction to obtain an application package name;

[0025] Obtaining an application identifier corresponding to the application package name;

[0026] According to the application identifier, the multimedia sound sources of the main driver's sound zone and the co-driver's sound zone are configured respectively, and a main driver's sound zone sound source list and a co-driver's sound zone sound source list are generated. The sound zones of the sound sources in the main driver's sound zone sound source list are different from those in the co-driver's sound zone sound source list.

[0054] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0055] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0056] The main solution of the embodiment of the present application is: in response to a control instruction of a first sound source, determining a target playback sound zone corresponding to the first sound source among multiple playback sound zones; controlling the first sound source to play independently of other playback sound zones outside the target playback sound zone, so that the playback process of a second sound source in other playback sound zones outside the target playback sound zone is not interrupted by the first sound source.

[0057] Since the existing technology can only play one multimedia audio source at the same time, the driver and co-driver cannot independently control and play the multimedia audio source, affecting the user experience.

[0058] This application provides a solution. In a single-screen scenario, the driver and front passenger can independently control the playback of media audio sources. The driver / front passenger playback audio zones can be automatically configured according to user operations, allowing the driver and front passenger to independently control and play multimedia audio sources, thereby improving the car networking experience.

[0059] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of implementing the above functions, a single-screen multimedia audio control device, etc. The following describes this embodiment and the following embodiments using a single-screen multimedia audio control device as an example.

[0060] Based on this, the embodiment of the present application provides a single-screen multimedia audio control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the single-screen multimedia audio control method of the present application.

[0061] In this embodiment, the single-screen multimedia audio control method includes steps S10 to S30:

[0062] Step S10: In response to a control instruction of a first sound source, determining a target playback sound zone corresponding to the first sound source among a plurality of playback sound zones.

[0063] It should be noted that the application scenario of this embodiment is a multimedia playback control scenario of a single screen in a vehicle. The first sound source is a multimedia sound source determined by the user through voice commands or screen click operations. The control instructions for the first sound source can be generated through voice commands or screen click operations to control the playback of the sound source. The location where the first sound source is played can be in the main driver playback sound zone or the co-driver playback sound zone. In this embodiment, the car screen is a single screen, that is, there is only one car screen between the main driver and the co-driver for operation and control. For example, if the user clicks on music software A through a click operation, the first sound source is music software A, and music is played through music software A. If the user generates a song switching instruction in music software A through a voice command, the first sound source is to switch songs in music software A.

[0064] The first sound source may be music software or video software, or a specific song or a specific video. For example, the first sound source may be music software B, video software C, or video software D, or the first sound source may be song E or video F.

[0065] During the driving of the vehicle, it is possible to detect in real time whether a control instruction from the first sound source is received. The first sound source may be an instruction issued by the driver or the co-driver.

[0066] In a specific implementation, the control instruction of the first audio source may be an instruction to switch the currently playing multimedia audio source, an instruction to stop playing the current multimedia audio source, an instruction to open a new multimedia audio source, etc., and may also include other instructions, which are not limited in this embodiment.

[0067] In a feasible implementation, step S10 may include steps A11 to A12:

[0068] Step A11: In response to the control instruction of the first sound source, the control instruction is parsed to determine the location of the target user;

[0069] It can be understood that after receiving the control instruction of the generated first sound source, the control instruction can be parsed. Specifically, the location of the user who issued the control instruction can be determined. The control instruction may include a voice instruction or a click instruction of the user clicking the screen. The target user is the user who issued the control instruction of the first sound source. In this embodiment, the target user includes the main driver user or the co-driver user.

[0070] In a feasible embodiment, step A11 may include: responding to the control instruction of the first sound source, parsing the control instruction; when the control instruction is a voice instruction of the target user, determining the location of the target user according to the voice direction of the voice instruction; or, when the control instruction is a click operation of the target user on the screen, determining the location of the target user according to the location of the click operation or the target user action recognized by the camera.

[0071] It should be noted that since the control instruction can be generated by the user by uttering voice or by clicking on the car screen, when the control instruction is a voice instruction of the target user, the voice direction of the target user when uttering the voice can be obtained, thereby obtaining the position of the target user. Specifically, the car screen in the car can be used as the origin in advance to establish a coordinate system of the position in the car, so as to collect the sound emitted by the user according to the microphone or voice sensor in the car, and when the voice instruction of the first sound source is received, the voice direction of the voice instruction is determined, thereby obtaining the position of the target user.

[0072] It can be understood that if the control instruction is for the main driver or co-driver in the car to click on the car screen, the click position of the user when clicking the screen can be determined or the user's click action can be collected through the camera in the car to determine the location of the target user. For example, the car screen is divided into two in advance, and the target user's click operation is determined to be on the left side of the car screen through buried points. The target user's position is determined to be the main driver's position. When the target user's click operation is on the right side of the car screen, the target user's position is determined to be the co-driver's position, or the camera in the car can be used to identify whether it is the main driver or the co-driver who is performing the click operation to determine the location of the target user.

[0073] Step A12: determining a target playback sound zone corresponding to the first sound source from the driver's seat playback sound zone or the passenger seat playback sound zone according to the position.

[0074] It should be noted that after determining the position of the target user, the playback sound zone to which the target user belongs can be determined based on the position. If the target user is in the main driver's seat, the target playback sound zone corresponding to the first sound source is the main driver's seat. If the target user is in the co-pilot seat, the target playback sound zone corresponding to the first sound source is the co-pilot's seat.

[0075] It should be noted that the control instructions of the first sound source can also be analyzed to determine the identification number of the first sound source. According to the identification number, it can be determined whether the first sound source is located in the main driver's seat playback sound zone or the co-driver's seat playback sound zone. The sound sources in the main driver's seat playback sound zone and the co-driver's seat playback sound zone are different, so the target playback sound zone corresponding to the first sound source can be determined.

[0076] Step S20: controlling the first sound source to play independently of other playback sound zones outside the target playback sound zone, so that the playback process of the second sound source in other playback sound zones outside the target playback sound zone is not interrupted by the first sound source.

[0077] In a specific implementation, if there is a current playback sound source, the playback sound zone of the first sound source may be the same as or different from the playback sound zone of the current multimedia sound source. The playback sound zone in this embodiment represents the playback position of the sound source or the source of the sound source. For example, if the playback sound zone of the first sound source is the sound source of the main driver's playback sound zone, and the playback sound zone of the current multimedia sound source is the sound source of the co-driver's playback sound zone, then the target playback sound zone of the first sound source is different from the playback sound zone of the current multimedia sound source. Figure 2 As shown, Figure 2 Schematic diagram of audio management for the main driver playback sound zone and the co-driver playback sound zone, including the main driver playback sound zone and the co-driver playback sound zone. For example, the main driver audio source 1 is playing and occupies the audio focus of the main driver playback sound zone. If the main driver switches to the main driver audio source 2 at this time, the main driver audio source 2 is controlled to play and occupy the audio focus of the main driver playback sound zone. The co-driver audio source 3 in the co-driver playback sound zone is playing and occupies the audio focus of the co-driver playback sound zone. If the co-driver switches to the co-driver audio source 4 at this time, the co-driver audio source 4 is controlled to play and occupy the audio focus of the co-driver playback sound zone.

[0078] If the first sound source and the current multimedia sound source are both sound sources of the main playback sound zone, the playback sound zone of the first sound source is the same as the playback sound zone of the current multimedia sound source.

[0079] It should be noted that if the playback zone of the first sound source is different from the playback zone of the current multimedia sound source, the first sound source will be controlled to play independently of other playback zones outside the target playback zone, and the issuance of the control command of the first sound source will not cause the currently playing audio to be paused. For example, if the first sound source is music software A in the main driver's seat playback zone and the current multimedia sound source is music software B in the passenger seat playback zone, then both music software A and music software B will play music in the corresponding playback zones. Or if the first sound source is song 1 in music software A in the main driver's seat playback zone and the current multimedia sound source is video software C in the passenger seat playback zone, then both song 1 and video software C will play music in the corresponding playback zones.

[0080] In a feasible implementation, step S20 may include: switching the currently playing sound source in the target playback sound zone to the first sound source.

[0081] It should be noted that if there is a sound source being played in the target playback sound zone, and the user issues a control command for the first sound source, it means that the user has a need to switch the sound source in the target playback sound zone. The sound source being played in the target playback sound zone can be switched to the first sound source. For example, if the sound source being played is music software A and the first sound source is music software B or video software C, then music software A is switched to music software B or video software C for playback. Or if the sound source being played is song 1 in music software A and the first sound source is song 2, then if song 2 has a playback source in music software A, then song 1 being played in the target playback sound zone is switched to song 2. If song 2 does not have a playback source in music software A, but has a playback source in music software B in the target playback sound zone, the user can be asked whether to open music software B to play song 2. If the user agrees, music software A is closed, and music software B is opened to play song 2 in the target playback sound zone through the playback device.

[0082] like Figure 3 As shown, Figure 3 This is a schematic diagram of multimedia audio source playback control. When there is a playback control instruction for the first audio source, the specific playback audio zone can be determined first. If the playback audio zone is the main driver's side playback audio zone, the playback channel corresponding to the audio zone is called for playback control. If the playback audio zone is the co-driver's side playback audio zone, the playback channel corresponding to the co-driver's side playback audio zone is called for playback control.

[0083] This embodiment provides a single-screen multimedia audio control method. In response to a control command from a first audio source, a target audio zone corresponding to the first audio source is determined from multiple audio zones. The method then controls the first audio source to play independently of other audio zones outside the target audio zone, ensuring that the playback of second audio sources in other audio zones outside the target audio zone is not interrupted by the first audio source. This ensures that the playback of the driver and passenger multimedia audio sources and the front passenger multimedia audio do not affect each other, allowing users to independently control and play different media audio, thereby enhancing the user experience.

[0084] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 4 , step S20 includes steps S201 to S202:

[0085] Step S201: determining a target sound zone sound source list according to the target playback sound zone.

[0086] In a specific implementation, each playback zone stores a corresponding sound source list. For example, the main driver's seat playback zone stores a main driver's seat sound source list, and the front passenger's seat playback zone stores a front passenger's seat sound source list. For example, the main driver's seat sound source list includes main driver's seat sound source 1, main driver's seat sound source 2, main driver's seat sound source 3, and main driver's seat sound source 4, while the front passenger's seat sound source list includes front passenger's seat sound source 1, front passenger's seat sound source 2, front passenger's seat sound source 3, and front passenger's seat sound source 4. The main driver's seat and front passenger's seat sound source playback zones are different. Therefore, the target sound source list can be determined by the target playback zone.

[0087] For example, if the target playback zone of the first sound source is the main driving zone, then the target zone sound source list is the main driving zone sound source list.

[0088] It is understandable that the audio source list for the driver's or passenger's audio zone can be configured in advance, thereby improving the efficiency of control when performing audio zone playback control. Therefore, before step S201, steps B11 to B14 are also included:

[0089] Step B11: providing a multimedia audio source configuration interface, so that the user can configure the audio source on the multimedia audio source configuration interface;

[0090] It should be noted that the multimedia sound source configuration interface is an interface for users to configure sound sources. When the user clicks on the screen, the sound source configuration of the corresponding sound zone can be entered.

[0091] Step B12: upon receiving a sound source configuration instruction from the user based on the multimedia sound source configuration interface, traversing the multimedia application list according to the sound source configuration instruction to obtain an application package name;

[0092] It can be understood that if a sound source configuration instruction is received from the user based on the multimedia sound source configuration interface, the multimedia application list can be traversed according to the sound source configuration instruction. A large number of multimedia applications are stored in the multimedia application list, such as music A, music B, video C, video D, mini program video E, etc. By traversing the multimedia application list, the application package name of each application, that is, application packagename, is obtained. The application package name of each application is unique, and the corresponding application can be quickly queried based on the application package name.

[0093] Step B13: Obtain the application identifier corresponding to the application package name;

[0094] In a specific implementation, an application identifier corresponding to the application package name, that is, the application uid, may be obtained. The application identifier of each application is unique.

[0095] Step B14: According to the application identifier, the multimedia sound sources of the main driver's seat playback sound zone and the front passenger's seat playback sound zone are respectively configured to generate a main driver's seat sound zone sound source list and a front passenger's seat sound zone sound source list. The playback sound zones of the playback sound sources in the main driver's seat sound zone sound source list and the playback sound zones of the playback sound sources in the front passenger's seat sound zone sound source list are different.

[0096] In a specific implementation, the multimedia sound sources of the main driver's seat playback sound zone and the co-driver's seat playback sound zone can be configured separately through application identifiers, thereby generating a main driver's seat sound zone sound source list and a co-driver's seat sound zone sound source list, and the playback sound zones of the two playback sound sources are different.

[0097] It should be noted that, for example, if the current audio source configuration instruction comes from the main driver's seat, the step of generating the audio source list for the main driver's seat audio zone may include:

[0098] Providing a multimedia audio source configuration interface so that the user can configure the audio source on the multimedia audio source configuration interface;

[0099] In a specific implementation, as described above, by providing a multimedia sound source configuration interface, the user can configure the sound source on the multimedia sound source configuration interface.

[0100] Upon receiving a sound source configuration instruction for the primary driver's seat playback zone based on the multimedia sound source configuration interface, traversing a multimedia application list according to the sound source configuration instruction for the primary driver's seat playback zone to obtain an application package name for the primary driver's seat playback zone;

[0101] In the specific implementation, if the configuration instruction is issued by the main driver, the multimedia audio source program list can be traversed according to the audio source configuration instruction of the main driver playback zone to obtain the audio source of the main driver that the user wants to configure. For example, if the user selects main driver audio source 1 and main driver audio source 2, the multimedia application list will be searched to obtain the application package names of main driver audio source 1 and main driver audio source 2.

[0102] Obtain an application identifier for the main driver's playback zone corresponding to the application package name of the main driver's playback zone;

[0103] The multimedia sound source of the main driver's seat playback sound zone is configured according to the application identifier of the main driver's seat playback sound zone, and a sound source list of the main driver's seat playback sound zone is generated.

[0104] In the specific implementation, the application identifiers corresponding to the application package names of the main driver audio source 1 and the main driver audio source 2 can be obtained, so that the multimedia audio source of the main driver playback sound zone can be configured through the application identifier to generate the main driver sound zone audio source list. Similarly, the configuration of the co-driver sound zone audio source list is the same as the main driver sound zone audio source list, but the audio source that has been configured in the main driver sound zone audio source list cannot be configured in the co-driver sound zone audio source list.

[0105] It is understandable that in addition to configuring the audio sources for each playback zone before the multimedia audio source is played, the audio sources for the playback zones can also be configured in real time when the user has a need to play the audio source, that is, each multimedia audio source is automatically configured to the driver's seat playback zone or the co-driver's seat playback zone. The specific implementation is as follows:

[0106] When a user taps the screen, the in-car camera (OMS) determines whether the user is currently tapping the screen, or by monitoring whether the user has tapped a multimedia source. Within 2 seconds, if the above conditions are met, the system determines that the current driver / passenger user has tapped multimedia source A and configured that source to the driver / passenger playback zone (a pop-up window may be displayed to prompt the user). Furthermore, when the user voice-activated multimedia source playback, the system determines whether the driver / passenger user is currently operating the source by waking up the zone, and configures the source to that zone. If the configured source playback zone is already in the user-defined configuration list, the system does not configure the source. Instead, a settings interface is provided to allow the user to customize the multimedia sources in the driver and passenger playback zones. For example, music A and music B may be configured in the driver's zone, while video C and mini-program video D may be configured in the passenger's zone, thereby generating a list of source sources for the driver and passenger zones.

[0107] In the specific implementation, in order to avoid conflicts during configuration, the main driver and the co-driver are not allowed to configure the sound source at the same time. Therefore, after providing the multimedia sound source configuration interface, it also includes: when the user's sound source configuration instructions for the main driver playback sound zone and the co-driver playback sound zone based on the multimedia sound source configuration interface are received at the same time, the sound source configuration of the playback sound zone is paused, and a reminder message is generated; according to the reminder message, the user is reminded to configure the main driver playback sound zone and the co-driver playback sound zone in turn.

[0108] It should be noted that if the audio source configuration instructions of the main driver user and the front passenger user are received at the same time, the audio source configuration will not be performed, that is, the audio source configuration of the playback zone will be paused. At the same time, a reminder message can be generated and displayed in a pop-up window to remind the user that the configuration cannot be performed at the same time, so that the main driver playback sound zone and the front passenger playback sound zone are configured separately or in sequence to avoid duplication or conflict in configuration.

[0109] Step S202: Based on the target sound zone sound source list, the first sound source is controlled to play independently of other playback sound zones outside the target playback sound zone.

[0110] It should be noted that after determining the target sound zone sound source list, the audio playback of the first sound source can be controlled according to the corresponding sound source in the target sound zone sound source list, so that the multimedia audio of the driver and the co-driver can be played simultaneously.

[0111] like Figure 5 As shown, Figure 5 This is a functional diagram of the module for automatic configuration of the sound source. The voice module, camera module, and tracking module are used to determine whether the user has configured the sound source. If so, the configuration module is used to configure the main driver's audio source in the main driver's playback zone and the co-driver's audio source in the co-driver's playback zone.

[0112] like Figure 6 As shown, Figure 6 This is a flowchart of automatic audio source configuration. Through voice wake-up or recognition and buried event monitoring, the user is determined to play multimedia audio source X. The system detects whether audio source X is in the custom configuration list. If so, no configuration is required. If not, the location of the wake-up person or the touch screen operation location is obtained. If the location is in the main driver's seat, the application package name is obtained, and the application UID is obtained to configure the audio source for the main driver's seat playback zone. If the location is in the front passenger seat, the application package name and application UID are obtained to configure the audio source for the front passenger seat playback zone.

[0113] This embodiment determines a target sound zone sound source list based on the target playback sound zone; based on the target sound zone sound source list, controls the first sound source to play independently of other playback sound zones outside the target playback sound zone. Intelligent sound zone allocation ensures that sound sources in different playback sound zones can be reasonably allocated to the most suitable playback area, avoiding conflicts between different sound source playback sound zones and improving the user's operating experience.

[0114] Based on the first embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 7 , step S202 includes steps S2021 to S2022:

[0115] Step S2021: Detect whether the first sound source exists in the target sound zone sound source list.

[0116] It should be noted that, in order to improve the control effect, after obtaining the target sound zone sound source list, it can be determined whether the first sound source exists in the target sound zone sound source list, so as to further perform playback control on the first sound source.

[0117] It should be understood that if the first sound source does not exist in the target sound zone sound source list, the first sound source can be configured at this time to improve subsequent control efficiency. Therefore, after step S3031, it also includes: when the first sound source does not exist in the target sound zone sound source list, displaying the multimedia sound source configuration interface; receiving the first sound source configuration instruction of the user based on the multimedia sound source configuration interface, and configuring the first sound source to the target sound zone sound source list according to the first sound source configuration instruction.

[0118] It can be understood that if the first sound source does not exist in the target sound zone sound source list, a multimedia sound source configuration interface is provided to allow the user to configure the sound source based on this configuration interface and configure the first sound source to the target sound zone sound source list. For example, if the first sound source is the main driving sound source, it will be configured to the main driving sound zone sound source list.

[0119] Specifically, during configuration, the device for sound source playback can also be set. The steps of configuring the playback device include: responding to a playback device configuration request; and configuring the playback device for the main driver's playback sound zone and the co-driver's playback sound zone respectively based on the playback device configuration request.

[0120] It should be noted that this playback device configuration request can be issued by the user or generated by the audio management module. If the user has no customized requirements, the playback device can be preset through the audio management model. If the user has customized requirements, the playback device is configured according to the user's customization, so as to configure the playback devices in the main driver's playback sound zone and the co-driver's playback sound zone separately. For example, the playback devices in the main driver's playback sound zone are configured as the main driver's headrest speakers, left front speakers, etc., and the playback devices in the co-driver's playback sound zone are configured as the co-driver's headrest speakers, right front speakers, headphones, etc.

[0121] Step S2022: When the first sound source exists in the target sound zone sound source list, the first sound source is played through the playback device in the target playback sound zone.

[0122] In specific implementations, when the first audio source exists in the target audio zone source list, the corresponding application is directly called for audio playback. When playing multimedia audio sources in the main driver's seat, control is performed within the main driver's seat playback zone and played through the main driver's device. When playing multimedia audio sources in the passenger seat, control is performed within the passenger seat playback zone and played through the passenger's device. This ensures that the main and passenger driver audio sources do not interfere with each other, allowing users to independently control and play different media music.

[0123] This embodiment detects whether the first sound source exists in the target audio zone's audio source list; if the first sound source exists in the target audio zone's audio source list, the first sound source is played via the playback device in the target audio zone. By pre-detecting whether the first sound source exists in the target audio zone's audio source list, the system can quickly confirm whether the content to be played already exists before audio playback, avoiding repeated loading or unnecessary resource requests, thereby improving playback efficiency, reducing audio source loading time, and enhancing the user experience.

[0124] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the single-screen multimedia audio control method of the present application.
