The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0027] The following describes the vehicle multimedia audio recovery method, device, electronic device, storage medium and program according to the embodiments of the present application with reference to the accompanying drawings.

[0028] Specifically, Figure 1 A flowchart of a vehicle multimedia audio recovery method provided in an embodiment of the present application.

[0029] like Figure 1 As shown, the vehicle multimedia audio recovery method includes the following steps:

[0030] In step S101 , the playback data, playback status, and media type of the current vehicle multimedia audio when the multimedia audio is interrupted are obtained.

[0031] It is understandable that the embodiment of the present application can obtain the playback data, playback status and media type of the current vehicle multimedia audio when the multimedia audio is interrupted, so as to restart the playback from the current position later.

[0032] In an embodiment of the present application, after obtaining the playback data, playback status and media type of the current vehicle multimedia audio when the multimedia audio is interrupted, it includes: encapsulating the playback data, playback status and media type of the current vehicle multimedia audio into a local database.

[0033] It can be understood that the embodiment of the present application can encapsulate the current vehicle multimedia audio playback data, playback status and media type into a local database, which not only solves the basic problems of data real-time, reliability, security, etc., but also achieves the comprehensive effects of multi-scenario precise recovery, energy efficiency optimization, and future expansion through the deep combination of structured storage and dynamic logic.

[0034] In an embodiment of the present application, before obtaining the playback data, playback status and media type of the current vehicle multimedia audio when the multimedia audio is interrupted, it includes: monitoring whether the multimedia audio triggers an interruption event; if the multimedia audio triggers an interruption event, obtaining the playback data, playback status and media type of the current vehicle multimedia audio when the multimedia audio is interrupted.

[0035] Among them, interruption events include: the car computer is in sleep mode, the external connection seizes the multimedia audio channel, and the system's internal sound source seizes the multimedia audio focus. Recovery events include car computer wake-up, the external connection releases the multimedia audio channel, and the system's internal sound source releases the multimedia audio focus.

[0036] Among them, the external connection channel preemption event and the external connection release of the multimedia audio channel are realized by monitoring the audio source management service of the vehicle system. When the first media type in the audio focus list is an external connection application, it is determined that the external connection preempts the audio channel; the system internal application preempts the audio focus event and the system internal sound source releases the multimedia audio focus by monitoring the audio focus changes of the target system; the vehicle sleep and vehicle wake-up are determined by monitoring the memory temporary system status.

[0037] It can be understood that the embodiments of the present application can monitor the status changes of multimedia audio in real time and record relevant information when an interruption occurs, so as to ensure that when the audio resumes playing, it can seamlessly return to the previous playback state without the user having to manually search and restart playback, thereby improving the user's auditory experience and realizing an automated audio playback recovery mechanism, which is not limited to the vehicle shutdown / startup scenario, but also includes various situations such as vehicle computer sleep / wake-up, external connection preemption / release of audio channels, system internal sound source preemption / release of audio focus, etc., thereby enhancing the intelligence level of the system.

[0038] In step S102 , it is identified whether the multimedia audio triggers a resume event.

[0039] It is understandable that the embodiment of the present application can identify whether the multimedia audio triggers a recovery event, so as to restore the multimedia playback audio.

[0040] In step S103 , if the multimedia audio triggers a resume event, the playback data, playback status, and media type of the current vehicle multimedia audio corresponding to the interruption moment are called to resume the multimedia audio.

[0041] It can be understood that in the embodiment of the present application, if the multimedia audio triggers a recovery event, the playback data, playback status and media type of the current vehicle multimedia audio corresponding to the interruption moment are called to restore the multimedia audio. Through the technical combination of multi-scene monitoring, real-time recording and dynamic recovery, the recovery capability and user experience after the vehicle audio interruption are significantly improved.

[0042] In an embodiment of the present application, before calling the playback data, playback status and media type of the current vehicle multimedia audio corresponding to the interruption moment to resume the multimedia audio, it includes: judging whether the playback status corresponding to the interruption moment is playing; if the playback status is playing, then pulling up the audio playback service of the corresponding media type according to the playback data of the current vehicle multimedia audio, and sending the playback instruction and target information to the media service and the vehicle terminal; if the playback status is non-playing status, then pulling up the audio playback service according to the playback data of the current vehicle multimedia audio and sending the target information to the vehicle terminal.

[0043] It can be understood that the embodiment of the present application can restore audio playback more accurately by judging the playback status (playing or non-playing status) at the time of interruption; if the playback status is playing, the audio playback service of the corresponding media type is directly pulled up and the playback instruction and target information (such as song / program information) are sent to ensure that playback continues from the breakpoint; if it is in the non-playing status, only the audio playback service is pulled up but not automatically played, and only relevant information is displayed. This can avoid unnecessary audio interference, and the user does not need to manually find the last playback position or reselect the playback content. Especially when the playback status is playing, the system can automatically resume playback, which greatly improves the user experience, makes the operation more convenient and smooth, and improves the user experience.

[0044] According to the vehicle multimedia audio recovery method proposed in the embodiment of the present application, the playback data, playback status and media type of the current vehicle multimedia audio when the multimedia audio is interrupted are obtained; it is identified whether the multimedia audio triggers a recovery event; if the multimedia audio triggers a recovery event, the playback data, playback status and media type of the current vehicle multimedia audio corresponding to the interruption moment are called to restore the multimedia audio. Through the technical combination of multi-scene monitoring, real-time recording and dynamic recovery, the recovery capability and user experience after the vehicle audio interruption are significantly improved.

[0045] The following will be combined Figure 2-Figure 5 The vehicle multimedia audio recovery method of this application is described as follows:

[0046] Step 1: When multimedia audio is active (play / pause) on the car computer, the playback information (song / program information), media type, and playback status are recorded in real time. When switching songs / programs, switching play / pause status, or switching media types, the currently playing multimedia information: playback information (song / program information), media type, and playback status are actively recorded;

[0047] Media types include: online music (such as QQ Music, Kugou Music), local music (Bluetooth music, USB music), online news / radio (LeTingToutiao / Himalaya), radio (FM / AM), etc.

[0048] Step 2: Monitor the car's sleep / wake-up events:

[0049] (1) This is achieved by monitoring the system STR status. The received STR status is divided into two types: sleep and wake-up;

[0050] Car computer sleep mode: If a multimedia audio source is currently playing, the playback will be paused; if no multimedia audio source is currently playing, no processing will be performed;

[0051] Car computer wake-up: query local files, if there is media playback record, restore multimedia audio status information; if there is no media playback record, do nothing;

[0052] (2) HiCar and CarPlay external connection preemption / release audio channel events: This is mainly achieved by registering the car system audio source management service to monitor audio changes. When the audio changes, the media type list will be passed to the upper layer. When the first media type in the focus list is a HiCar or CarPlay application, it is determined that the external connection preempts the audio channel. Otherwise, the external connection releases the audio channel;

[0053] (2.1) An external connection has seized the multimedia audio channel: If a multimedia audio source is currently playing, the playback is paused; if no multimedia audio source is currently playing, no processing is performed;

[0054] (2.2) The external connection releases the multimedia audio channel: query the local file, and if there is a media playback record, restore the multimedia audio status information; if there is no media playback record, do nothing;

[0055] (3) Applications in the vehicle system seize / release audio focus events: This is achieved by monitoring the Android system audio focus changes;

[0056] (3.1) The system's internal audio source seizes the multimedia audio focus:

[0057] If a multimedia audio source is currently playing, pause the playback; if no multimedia audio source is currently playing, do nothing;

[0058] (3.2) The system's internal audio source releases the multimedia audio focus: query the local file. If there is a media playback record, restore the multimedia audio status information; if there is no media playback record, do nothing.

[0059] Step 3: Perform multimedia audio recovery steps

[0060] Get multimedia audio playback records and restore media information:

[0061] If the playback status in the record is playing, the corresponding media audio playback service will be pulled up according to the media type, and the playback instructions and song / program information will be sent to the media service and external display window (instrument, desktop card, etc.); if the playback status in the record is non-playing, only the media audio service will be pulled up without playing, and the song / program information will be sent to the external display window (instrument, desktop card, etc.).

[0062] In summary, this application can resume multimedia audio playback in time after audio playback is interrupted in various situations, avoiding the trouble of re-searching the sound source and manually clicking to resume playback, thereby improving the user's listening experience; it records multimedia audio playback status and other information in real time and stores it in local files, with high timeliness and accurate recording, and does not need to rely on external trigger conditions.
