摘要
It is possible to suppress an increase in the transmission amount of the control message, and provides the audio-video data synchronization method which can avoid the output of the video is stopped. When indicating that the connection state information changes from invalid to valid, audiovisual data synchronization method, audio output, the reproduction capability information including information indicating a first delay is the time required for the video image output by the video output device a first sound output step of adjusting the first delay amount acquisition step of device to obtain from the video output device, the timing of the audio output device to output audio based on the first delay amount, required for video output video output step When indicating a second delay amount acquisition step of the video output device to obtain a second delay time, the connection state information is valid, and shows a second delay obtained by the second delay amount acquisition step including a delay transmission step of transmitting to the audio output device from the image output device, a control message including the information, and a second sound output step of adjusting the timing of the audio output device to output audio based on the second delay .
