Claim:
1. An audio/video signal synchronization method, comprising: acquiring a delay data value of an audio signal formed by a wireless module of an audio/video signal synchronization apparatus and a wireless loudspeaker box device; calculating playing time of each frame of a video data to be played according to a display format of the video data to be played; calculating the number of frames to be buffered according to the delay data value and the playing time of each frame, and generating and buffering the corresponding number of frames; and playing the buffered frames sequentially according to an audio/video playing instruction, and transmitting an audio data corresponding to the video data to be played to a wireless audio device while playing the buffered frames, so that the audio data is played on the wireless audio device; wherein the acquiring the delay data value of the audio signal comprises: determining whether the wireless module in the audio/video signal synchronization apparatus is a plug-in module; if the wireless module is not a plug-in module, acquiring a delay time value of the wireless module of the audio/video signal synchronization apparatus by itself and a delay time value of the wireless loudspeaker box device, and taking the sum of the delay time value of the wireless module and the delay time value of the wireless loudspeaker box device as the delay data value of the audio signal; otherwise if the wireless module is a plug-in module, generating a prompt message to inform a user to input a delay time value of the plug-in module; and receiving the delay time value of the plug-in module input by the user, acquiring the delay time value of the wireless loudspeaker box device, and taking the sum of the delay time value of the plug-in module and the delay time value of the wireless loudspeaker box device as the delay data value of the audio signal.
