AUDIO/VIDEO SIGNAL SYNCHRONIZATION METHOD AND APPARATUS

摘要

Disclosed is an audio/video signal synchronization method which includes: acquiring a delay data value of an audio signal formed by a wireless module of an audio/video signal synchronization apparatus and a wireless audio device; according to a display format of a video data to be played, calculating playing time of each frame of the video data to be played; according to the delay data value and the playing time of each frame, calculating the number of frames to be buffered, and generating and buffering the frames with the corresponding number; and according to an audio/video playing instruction, playing the buffered frames and the video data to be played sequentially, and transmitting audio data corresponding to the video data to be played to the wireless audio device to play the audio data while playing the buffered frames. Also disclosed is an audio/video signal synchronization apparatus.
