Title:
AUDIO/VIDEO PLAY SYSTEM, VIDEO DISPLAY DEVICE, AND AUDIO OUTPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/069081
Kind Code:
A1
Abstract:
An audio decoding (108) is carried out within a video display device (10), and a frame number (AC) of the decoded audio is wirelessly transmitted, together with audio data, to an audio output device (20). An audio frame number (RC) is returned from the audio output device (20) to the video display device (10). The timing of a video decoding (106) is controlled such that a video frame number (VC) which is decoded within the video display device (10) matches the returned audio frame number (RC). Even if it is not possible to predict a delay for transmission from the video display device to the audio output device, etc., or said delay fluctuates, it is possible to synchronize video display with audio output.
