Abstract
Audio decoding () is carried out in a video display device (), and a frame number (AC) of the decoded audio is wirelessly transmitted, together with audio data, to an audio output device (). An audio frame number (RC) is returned from the audio output device () to the video display device (). The timing of video decoding () is controlled such that the frame number (VC) of the video decoded in the video display device () matches the returned audio frame number (RC). Even if it is not possible to predict the delays such as those involved with transmission from the video display device to the audio output device, and even if the delays fluctuate, it is possible to synchronize the video display with the audio output.
