Based on the distributed soft bus provided by the application, the audio information acquired by the plurality of recording devices and the video information acquired by the plurality of recording devices are synchronized and synthesized, so that the audio and video information corresponding to the terminal device is generated. Therefore, the required output or input audio and video can be correspondingly and synchronously processed according to the distributed characteristic of the Hongmon system, and the required audio and video information can be obtained.
And S102, based on the distributed soft bus, according to the device information and the environment information of the plurality of playing devices, carrying out synchronous processing on the audio and video information to obtain target audio and video data corresponding to each playing device.
The target audio and video data is synchronized according to the playing setting information of each playing device. The playing setting information can be determined according to the device information and the environment information, so that the terminal device can synchronously process the audio and video information according to the playing setting information corresponding to each playing device.
In some embodiments, the playing setting information corresponding to each playing device is obtained according to the device information and the environment information of the plurality of playing devices; and according to the playing setting information, synchronously processing the audio stream and the video stream in the audio and video information to obtain target audio and video data corresponding to each playing device.

For example, if the playback device includes bass sound, the playback device may be determined to be in the bass mode according to the parameter information and the environment information of the playback device and the mode specific to the playback device.
For example, if the application scene of the playing device is a scene of recovering the radio, it may be determined that the playing device is in the pure human voice mode according to the parameter information, the environment information, and the user requirement of the playing device.
For example, if the application scene of the playback device is a movie or a scene such as a live broadcast, it may be determined that the playback device is in a live broadcast mode or a movie mode according to the parameter information, the environment information, and the user requirement of the playback device.
In some embodiments, the environment information includes position information, environment brightness information, and environment noise information of a user and each of the playback devices; determining the distance between the user and each playing device according to the position information; and determining the playing setting information of each playing device according to the distance, the ambient brightness information and the ambient noise information. Thereby, the playing setting information of the playing device can be accurately determined according to the environment information.
The user and each playing device are located in a preset space within a certain range, the position information of the user is used for indicating the position of the user in the preset space, and the position information of the playing device is used for indicating the position of the playing device in the preset space. The ambient brightness information is the ambient brightness of the position where the playing device is located, and the ambient noise information is the noise level of the position where the playing device is located.

Illustratively, if a first playing device and a second playing device exist, if the distance between the user and the first playing device exceeds a preset distance threshold, it indicates that the distance between the user and the first playing device is far, and the distance between the user and the first playing device is very close, at this time, the playing volume of the first playing device can be set to a high point, and the playing volume of the second playing device can be set to a low point, so that the playing volumes of the first playing device and the second playing device received by the user are the same, and meanwhile, the playing time of the audio stream of the first playing device is preset for a preset time, thereby avoiding that the audio played by the first playing device and the second playing device is echoed, and affecting the user experience.
The preset distance threshold may be any distance, such as 10m; the preset time may be any time, such as 0.1s, and is not limited in this respect.
For example, if the ambient brightness of the playback device is lower than the preset ambient brightness, it indicates that the environment where the playback device is located is dark, and at this time, it may be determined that the screen brightness of the playback device is lower. Therefore, the eyes of the user can adapt to a darker environment conveniently, and the film watching experience of the user is improved.
The preset ambient brightness may be any brightness value, and is not specifically limited herein.
For example, if the ambient noise decibel of the playback device is lower than the preset noise decibel, it indicates that the ambient noise level of the playback device is higher, and at this time, the playback volume setting up point of the playback device may be determined. Therefore, the situation that the user cannot clearly hear the audio played by the playing device due to the influence of noise can be avoided.

Therefore, the playing setting information can be corrected according to the synchronous demand information, and the target audio and video data which better meets the user demand can be obtained.
The synchronous demand information may include demand information input by a user, for example, the demand information indicates that the influence of the distance is not considered, the distance factor is not considered during synchronous processing, for example, the demand information indicates that noise is set to be removed, and at this time, only human voice is saved during synchronous processing. The synchronous parameter is the playing setting information needing to be corrected.
Illustratively, if the requirement information input by the user indicates that the influence of the distance is not considered, the synchronization parameter is the distance between the user and each of the playing devices, so as to correct the playing setting information, so that the distance factor is not considered when subsequently performing synchronization processing on the audio stream and the video stream in the audio and video information.
Illustratively, if the requirement information input by the user indicates that noise is set to be removed, the synchronization parameter is ambient noise information, so as to modify the playing setting information, so that the noise factor is not considered when the audio stream and the video stream in the audio and video information are synchronized subsequently.
In some embodiments, the playing setting information includes frame rate configuration information and frequency configuration information, and according to the frame rate configuration information, frame division analysis and frame rate conversion processing are performed on a video stream in the audio and video information to obtain a target video stream corresponding to the playing device; according to the frequency configuration information, performing track splitting analysis and frequency conversion processing on the audio stream in the audio and video information to obtain a target audio stream corresponding to the playing device; and generating target audio and video data corresponding to the playing equipment according to the target video stream and the target audio stream. Therefore, frame rate conversion can be carried out on the video stream and frequency conversion can be carried out on the audio stream, and therefore target audio and video data which meet the requirements of users better can be obtained.
The target video stream is a video stream subjected to frame rate conversion, and the target audio stream is an audio stream subjected to frequency conversion.
Specifically, according to frame rate configuration information, each frame of picture in the video stream in the audio/video information is analyzed, and frame rate conversion processing is performed according to the frame rate supported by the playing device, so as to obtain a target video stream corresponding to the playing device.
Specifically, according to the frequency configuration information, the audio of each track in the audio stream in the audio and video information is analyzed, and frame rate conversion processing is performed according to the frequency supported by the playing device, so as to obtain a target audio stream corresponding to the playing device.
In some embodiments, timestamp information of the target video stream and timestamp information of the target audio stream are obtained; and according to the timestamp information, performing time calibration and integration processing on the target video stream and the target audio stream to generate target audio and video data corresponding to the playing equipment. Therefore, the target video stream and the target audio stream of each playing device can be synchronized, and the condition that the sound and the picture are not synchronized is avoided.
The time stamp information of the target video stream includes the playing time of the first frame picture in the target video stream, and the time stamp information of the target audio stream includes the playing time of the audio corresponding to the first frame picture in the target audio stream.
Specifically, according to the timestamp information, time calibration is performed on the playing time of a first frame picture in the target video stream and the playing time of an audio corresponding to the first frame picture in the target audio stream, so that the playing time of the first frame picture in the target video stream is matched with the playing time of the audio corresponding to the first frame picture in the target audio stream, and finally, the frame pictures and the audio of multiple tracks are integrated to generate target audio and video data corresponding to the playing device.
And S103, sending the target audio and video data to the corresponding playing devices so that each playing device plays according to the corresponding target audio and video data.
The target audio and video data are the audio and video data which are synchronously processed according to the playing devices, when the playing devices play the corresponding target audio and video data, not only can the sound and picture synchronization of the playing devices be realized, but also the audio synchronization and the video synchronization among a plurality of playing devices can be realized, meanwhile, the playing setting of each playing device meets the requirements of users, and the use experience of the users on each playing device is improved.
In some embodiments, the target audio and video data is sent to the corresponding playing devices, so that each playing device plays according to the corresponding target audio and video data, and a device interface corresponding to the playing device is determined according to the interface information, so that the target audio and video data is sent to the corresponding playing device through the device interface. Therefore, the target audio and video data can be sent to the playing device through the device interface corresponding to the playing device. Because the distributed synchronous integration is based on the framework of distributed sister, the data circulation between the interfaces is fast, and the synchronous speed is fast.
Specifically, different playing devices may correspond to different device interfaces, so that interface information corresponding to the playing device needs to be acquired, and a device interface corresponding to the playing device is determined according to the interface information, so that target audio/video data can be quickly and accurately sent to the corresponding playing device through the device interface, so that each playing device plays according to the corresponding target audio/video data, and thus, each playing device can play audio/video synchronously.
