Abstract
A method in control equipment for synchronizing audio and video acquires an identifier of playback equipment. Information as to audio and video formats for the playback equipment is acquired playback and a first time delay data corresponding to the audio data and video data from the cloud server is set according to the identifier, the audio format information and the video format information. A first delay time between the audio data and video data according to the first time delay data acquired from the cloud server is set for the implementation of audio and video synchronization.
Claims14
A control equipment electronically connected to a cloud server and a playback equipment, wherein the control equipment transmits audio data and video data, the control equipment comprising:
- at least one processor;
- a storage unit;
- and
- one or more programs that are stored in the storage unit and executed by the at least one processor, the one or more programs comprising instructions for:
- acquiring an identifier of the playback equipment;
- acquiring a first format information of the audio data transmitted by the control equipment and a second format information of the video data transmitted by the control equipment;
- acquiring a first time delay data corresponding to the audio data and video data from the cloud server according to the identifier, the first format information and the second format information;
- setting a first delay time of the audio data and video data according to the first time delay data acquired from the cloud server to implement audio and video synchronization;
- determining whether the audio and video synchronization is implemented;
- and
- transmitting a second time delay data corresponding to the audio data and video data to the cloud server when the audio and video synchronization is implemented.
A cloud server electronically connected to a control equipment and a playback equipment, wherein the control equipment transmits audio data and video data, the cloud server comprising:
- at least one processor;
- a storage unit;
- and
- one or more programs that are stored in the storage unit and executed by the at least one processor, the one or more programs comprising instructions for:
- pre-storing a time delay table, wherein the time delay table stores a first delay time of the audio data and video data of different playback equipment with the process of starting audio, video decoding and playing for different formats of audio data and video data;
- receiving an identifier uploaded by the playback equipment;
- receiving a first format information of the audio data and a second format information of video data transmitted by the playback equipment;
- acquiring a first time delay data corresponding to the audio data and video data from the time delay table according to the identifier, the first format information of the audio data and the second format information of the video data;
- and
- transmitting the first time delay data to the control equipment.
A method of implementing audio and video of control equipment synchronization, wherein the control equipment is electronically connected to a cloud server and a playback equipment, wherein the control equipment transmits audio data and video data to the playback equipment, the method comprising:
- acquiring an identifier of the playback equipment;
- acquiring a first format information of the audio data transmitted by the control equipment and a second format information of the video data transmitted by the control equipment;
- acquiring a first time delay data corresponding to the audio data and video data from the cloud server according to the identifier, the first format information of the audio data and the second format information of the video data;
- setting a first delay time of the audio data and video data according to the first time delay data acquired from the cloud server to implement audio and video synchronization;
- determining whether audio and video synchronization is implemented;
- and
- transmitting a second time delay data corresponding to the audio data and video to the cloud server when audio and video synchronization is implemented.
A method of implementing audio and video of a cloud server synchronization, wherein the cloud server is electronically connected to a control equipment and a playback equipment, wherein the control equipment transmits audio data and video data to the playback equipment, the method comprising:
- pre-storing a time delay table, wherein the time delay table stores a first delay time of the audio data and video data of different playback equipment with the process of starting audios, video decoding and playing for different formats of audio data and video data;
- receiving an identifier uploaded by the playback equipment;
- receiving a first format information of the audio data and a second format information of video data transmitted by the playback equipment;
- acquiring a first time delay data corresponding to the audio data and video data from the time delay table according to the identifier, the first format information of the audio data and the second format information of the video data;
- and
- transmitting a second time delay data to the control equipment.
