In a video-audio synchronizing method for synchronizing video and audio reproduced respectively by a monitor 300 and an amplifier 400 connected to a serial bus 100 to which video from a DVD player 200 and audio associated with the video are supplied, the monitor 300 sends out delay time information caused by an intrinsic delay element for video display to the amplifier 400 through the serial bus 100 as a control command, and the amplifier 400 delays the audio by time necessary for synchronization between the video and the audio according to the control command and outputs the audio.
