    摘要： A video signal and an audio signal are TMDS transmitted from a source device to a sink device. Through a reserved line and a HPD line provided separately from a TMDS transmission line, an Ethernet™ signal is bidirectionally transmitted, and also, a SPDIF signal is transmitted from the sink device to the source device. The Ethernet™ signal bidirectionally transmitted between Ethernet™ transmitter/receiver circuits is differentially transmitted by an amplifier and is received by the amplifier. The SPDIF signal from a SPDIF transmitter circuit is common-mode transmitted from an adder and is received by the adder to be supplied to the SPDIF receiver circuit.

    摘要： A television receiver computes a delay time of an image displayed on the television receiver with respect to an audio signal transmitted from the television receiver to an audio amplifier, based on video delay information as EDID data, delay information transported from a disc recorder and information of a time required until audio data received from the disc recorder is transmitted to an audio amplifier. The audio amplifier controls a delay time lasting until the audio responsive to the received audio data is outputted so that the delay time matches the aforementioned delay time. Thereby, the displayed image in the television receiver and the audio output in the audio amplifier are synchronized.
