Abstract

The invention provides a sound and picture synchronization method and display equipment. The display equipment can firstly determine the target film source selected by the user, then acquire the film source information of the target film source, and then acquire the target audio delay time corresponding to the target film source according to the film source information. The video data and the audio data of the target film source start to be processed at the same time in the display equipment, and the target audio delay time represents the time for continuously processing the video data after the audio data is processed. Moreover, the display equipment caches the audio data within the target audio delay time while processing the video data. If the target audio delay time ends, the video data processing is completed, and at the moment, the display equipment plays the cached audio data and the processed video data at the same time. Therefore, the sound and the picture of the target film source can be kept consistent, and the problem of sound and picture desynchrony is avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an audio-video synchronization method and a display device. Background technique [0002] The audio data and video data of the film source in the display device need to be processed separately before they can be played on the display device. However, the processing flow of video data is more time-consuming than the processing flow of audio data. Furthermore, in the display device, it usually occurs that: after the audio data is processed and starts to play, the video data has not been processed; After the video data processing is completed, the audio data has been played for a period of time. These situations will cause problems such as sound but no picture when the source is played, or the sound and picture cannot be matched, etc. The sound and picture are out of sync. Contents of the invention [0003] The present application provides a method for synchronizing a...
