[0026] Figure 1 This is a flow chart of a vehicle audio playback method provided in an embodiment of the present disclosure. The method provided in an embodiment of the present disclosure can be executed by a vehicle audio playback device, which can be implemented using software and / or hardware and can be integrated on any electronic device with computing capabilities, such as a vehicle-mounted terminal.

[0027] like Figure 1 As shown, the audio playback method of a vehicle provided by the embodiment of the present disclosure may include:

[0028] Step 101: in response to a domain controller providing at least one audio source, obtaining a playing mode of each audio source according to preset configuration information.

[0029] In this embodiment, the domain controller is used to provide a video source and an audio source, and optionally, the video source corresponds to the audio source one by one. The configuration information is used to determine the playback mode of the audio source, and the playback mode includes a directional sound mode (DS mode) and a non-directional sound mode (NDS mode).

[0030] As an example, based on the number of audio sources, the playback mode of each audio source is determined according to a preset first correspondence. In this example, the first correspondence is the correspondence between the number of audio sources and the playback mode. For example, when the number of audio sources is 1, the playback mode of the audio source is determined to be NDS mode, otherwise, the playback mode of the audio source is determined to be DS mode.

[0031] As another example, based on the identification information of each audio source, the playback mode of each audio source is determined according to a preset second correspondence. In this example, the identification information of the audio source is used to distinguish different audio sources. For example, the audio source of the navigation voice, the audio source of the movie, and the audio source of the music correspond to different identification information. The second correspondence is the correspondence between the identification information of the audio source and the playback mode. For example, the playback mode corresponding to the identification information of the navigation voice audio source is the NDS mode, and the playback mode corresponding to the identification information of the movie audio source is the DS mode.

[0032] As another example, a preset default playback mode is used as the playback mode for all audio sources. In this example, when the default playback mode is NDS mode, in response to the domain controller providing the audio source, the playback mode for all audio sources is determined to be NDS mode, and when the default playback mode is DS mode, in response to the domain controller providing the audio source, the playback mode for all audio sources is determined to be DS mode.

[0033] Step 102, for a first audio source whose playback mode is a directional sound mode, the audio data of the first audio source is transmitted to a directional sound playback module of a screen in the vehicle through a video link.

[0034] In this embodiment, a screen is provided in the vehicle for displaying video content, and a directional sound playback module is also provided corresponding to the screen in the vehicle.

[0035] In actual application scenarios, the video link is used to transmit the video data of the video source, and the video content is displayed by transmitting the video data to the screen inside the vehicle. In this embodiment, for the first audio source with a directional sound mode of playback, the audio data of the first audio source is transmitted to the directional sound playback module of the screen inside the vehicle through the video link to achieve directional sound playback.

[0036] Optionally, the vehicle includes multiple screens, each screen is provided with a corresponding directional sound playback module, and for multiple first audio sources of the directional sound mode, the multiple first audio sources are respectively assigned to different directional sound playback modules. For example, the audio source of the navigation voice is assigned to the directional sound playback module of the central control screen, and the audio source of the movie is assigned to the directional sound playback modules of other screens.

[0037] The transmission process of the audio data of the first audio source in the video link is as follows.

[0038] As an example, the domain controller sends the first audio source to the serializer through the preset video interface, converts the data stream that meets the preset video protocol in the first audio source into a serial signal through the serializer, and transmits it to the deserializer through the serial link, and then parses the serial signal into a data stream that meets the preset video protocol through the deserializer, and parses the data stream that meets the preset video protocol into a data stream of the preset audio protocol through the driver board of the screen, and sends the data stream of the preset audio protocol to the directional sound playback module corresponding to the screen. Among them, the preset video interface includes the eDP interface and the DP interface, the preset video protocol includes the eDP protocol and the DP protocol, and the preset audio protocol includes the TDM protocol and the I2S protocol.

[0039] Step 103: Play the audio data of the first audio source through the directional sound playing module.

[0040] In this embodiment, for multiple first audio sources, audio data of different first audio sources are played respectively through different directional sound playback modules, so that when people in the vehicle watch different content through different screens, the audios will not interfere with each other, thereby meeting the needs of multiple people using different screens to watch different content.

[0041] In one embodiment of the present disclosure, for a second audio source in a non-directional sound mode, audio data of the second audio source is transmitted to a speaker via an audio link, and the audio data of the second audio source is played via the speaker, wherein the speaker is used for playing stereo, surround sound, and the like.

[0042] In actual application scenarios, the audio link is used to transmit the video data of the video source, and the audio data is transmitted to the speaker to achieve sound playback. In this embodiment, for the second audio source in the non-directional sound mode, the audio data of the second audio source is transmitted to the speaker through the audio link, wherein the TDM data streams required by different channels are parsed to drive different speakers to generate stereo or surround sound.

[0043] According to the technical solution of the embodiment of the present disclosure, in response to the domain controller providing at least one audio source, the playback mode of each audio source is obtained according to the preset configuration information. For the first audio source whose playback mode is the directional sound mode, the audio data of the first audio source is transmitted to the directional sound playback module of the screen in the vehicle through the video link, and the audio data of the first audio source is played through the directional sound playback module. Therefore, compared with the current playback mode of multiple screens in the vehicle, for the audio source in the directional sound mode, the audio is played by the whole vehicle speaker through the audio link, and then switched to the directional sound playback module corresponding to each screen, so that when people in the vehicle watch different content through different screens, the audio will not interfere with each other, thereby meeting the needs of multiple people using different screens to watch different content and improving the user experience.

[0044] Based on the above embodiments, Figure 2 A flowchart of another audio playback method for a vehicle provided by an embodiment of the present disclosure is shown as follows: Figure 2 As shown, the method includes:

[0045] Step 201: In response to a domain controller providing at least one audio source, based on the number of audio sources, a playback mode of each audio source is determined according to a preset first corresponding relationship.

[0046] In this embodiment, the playback mode is a directional sound mode or a non-directional sound mode. Optionally, the screen includes a central control screen, a co-pilot screen, and at least one rear screen. If the number of audio sources provided by the domain controller is one, the playback mode of the audio source is determined to be a non-directional sound mode. If the number of audio sources provided by the domain controller is two, the playback modes of the two audio sources are determined to be a directional sound mode and / or a non-directional sound mode. If the number of audio sources provided by the domain controller is greater than or equal to three, the playback modes of all audio sources are determined to be a directional sound mode.

[0047] As an example, the central control screen serves the driver's space, the co-pilot screen serves the co-pilot space, and the rear screen serves the rear space. The three screens can use the same video source at the same time or use different video sources independently. When the three screens use the same video source, that is, the number of audio sources provided by the domain controller is one, and the audio source adopts the NDS mode. When the three screens use two video sources, you can choose to use the NDS mode or the DS mode. For example, the central control screen displays map navigation information, and the co-pilot screen and the rear screen play the same movie. If only the NDS mode is used, the navigation prompt sound and the movie audio are played synchronously through the speaker. If the NDS mode and the DS mode are used, the movie audio adopts the NDS mode and the navigation prompt sound adopts the DS mode, that is, the movie audio is played through the speaker, and the navigation prompt sound is played through the directional sound playback module corresponding to the central control screen; if only the DS mode is used, the navigation prompt sound is played through the directional sound playback module corresponding to the central control screen, the movie audio is played through the directional sound playback module corresponding to the co-pilot screen, and the movie audio is played through the directional sound playback module corresponding to the rear screen. When the three screens use three different video sources, the DS mode is adopted. For example, the central control screen displays map navigation information, and the co-pilot screen and the rear screen play movie one and movie two respectively. Then the navigation prompt sound is played through the directional sound playback module corresponding to the central control screen, the audio of movie one is played through the directional sound playback module corresponding to the co-pilot screen, and the audio of movie two is played through the directional sound playback module corresponding to the rear screen. Due to the use of the directional sound playback module, the audio of the driver space, co-pilot space and rear space do not interfere with each other.

[0048] Step 202: When a request for switching the playing mode of any audio source among at least one audio source is detected, a prompt message is generated.

[0049] In this embodiment, a switching option can be set in the menu of the display interface displayed on the screen. When it is detected that the switching option is triggered, it is determined that a request to switch the playback mode of the audio source currently playing on the screen is detected. At this time, a prompt message is generated, which is used to prompt the user to confirm whether to switch the playback mode.

[0050] It should be noted that the selection and switching of the playback mode can be carried out in different ways, including but not limited to buttons, touch screens, voice commands, gesture commands, etc.

[0051] Step 203, if a confirmation instruction for the prompt information is obtained within a preset time, the playback mode of any audio source is switched from the directional sound mode to the non-directional sound mode, or the playback mode of any audio source is switched from the non-directional sound mode to the directional sound mode.

[0052] In this embodiment, for an audio source in a directional sound mode, if a confirmation instruction is obtained within a preset time, the playback mode of the audio source is switched to a non-directional sound mode. For an audio source in a non-directional sound mode, if a confirmation instruction is obtained within a preset time, the playback mode of the audio source is switched to a directional sound mode.

[0053] Among them, the preset time can be set as needed, and the confirmation instruction includes but is not limited to buttons, touch screens, voice commands, gesture commands, etc.

[0054] As an example, when the vehicle system is powered on, the SOC reads the default settings in the register and sets the audio source corresponding to each screen to NDS mode or DS mode. When multiple audio sources are detected, the SOC first executes the default settings in the register, and prompts through the screen and speaker to confirm whether to switch the playback mode. If a confirmation instruction is obtained within the preset time, the playback mode of the audio source is changed. If multiple audio sources are not detected or the corresponding settings are not made, the menu input is detected. If a playback mode switching request is detected in the menu, a prompt is given through the screen and speaker to confirm whether to switch the playback mode. If a confirmation instruction is obtained within the preset time, the playback mode of the audio source is changed.

[0055] Step 204, for the first audio source whose playback mode is the directional sound mode, the audio data of the first audio source is transmitted to the directional sound playback module of the screen in the vehicle through the video link, so that the audio data of the first audio source is played through the directional sound playback module.

[0056] In this embodiment, the domain controller sends the first audio source to the serializer through the preset video interface, converts the data stream in the first audio source that meets the preset video protocol into a serial signal through the serializer, and transmits it to the deserializer through the serial link. Then, the serial signal is parsed into a data stream that meets the preset video protocol through the deserializer, and the data stream that meets the preset video protocol is parsed into a data stream of the preset audio protocol through the driver board of the screen, and the data stream of the preset audio protocol is sent to the directional sound playback module corresponding to the screen.

[0057] Step 205: For a second audio source whose playing mode is a non-directional sound mode, the audio data of the second audio source is transmitted to a speaker through an audio link, so that the audio data of the second audio source is played through the speaker.

[0058] Reference Figure 3 , Figure 3This is a schematic diagram of data transmission, which involves a domain controller (DomainController), a video link (Video Link), and an audio link (Audio Link). For the NDS mode, the video processing process is as follows: In the domain controller, the SOC sends the video source to the SER through the DP / eDP interface. The SER converts the data stream that meets the eDP / DP protocol into a serial signal that supports long-distance transmission and sends it to the DES. In turn, the DES parses the serial signal and converts it into a data stream that meets the eDP / DP protocol. The TCON converts the eDP / DP data stream into an LVDS signal that can drive the display (screen). The audio processing process is as follows: In the domain controller, the SOC sends the audio source to the A2B Master through the TDM interface. The A2B Master converts the data stream that meets the TDM protocol into an A2B signal that supports long-distance transmission and sends it to the A2BSlave. The A2B Slave then parses the A2B signal and converts it into a data stream that meets the TDM protocol. The Audio DSP (audio digital signal processor) receives the TDM data stream received from the A2B Slave and parses the TDM data stream required for different channels. The TDM data streams of different channels are sent to different Audio PAs (audio power amplifiers) to drive different Speakers to achieve stereo or surround sound. For DS mode, in the domain controller, SOC sends the video source and audio source to SER through the eDP or DP interface. SER converts the data stream that meets the eDP / DP protocol into a serial signal that supports long-distance transmission and sends it to DES. Then, DES parses the serial signal and converts it into a data stream that meets the eDP / DP protocol. TCON parses the eDP / DP data stream into LVDS data stream and TDM / I2S data stream. The LVDS data stream is used to drive the screen, and the TDM / I2S data stream is sent to DSM to achieve directional sound playback.

[0059] According to the technical solution of the embodiment of the present disclosure, when there is a need for multi-source playback or privacy playback, the audio is switched from the vehicle speakers to the directional sound playback modules corresponding to each screen through an audio link, so that when people in the vehicle watch different content through different screens, the audio will not interfere with each other, thereby meeting the needs of multiple people using different screens to watch different content and improving the user experience.
