摘要：
A video signal and an audio signal are transmitted from a source device to a sink device in conformity with respective predetermined interfaces through respective transmission channels. The respective interfaces include bidirectional interface such as an HDMI and an IEEE1394. A controller acquires delay information (TLv) representing the total delay time of the devices connected to the transmission channels conforming to the bidirectional interface and corrects the difference in reproduction time between the video and audio signals by using the acquired delay information (TLv).
