    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.

    摘要： The present invention relates to a communication system, a transmitter, a receiver, a communication method, a program, and a communication cable for providing high-speed bidirectional communication while maintaining compatibility. When an HDMI (R) source performs bidirectional IP communication with an HDMI (R) sink using a CEC line and a signal line, a switching control unit controls a switch so that, when data is transmitted, the switch selects a constituent signal forming a differential signal output from a converting unit and, when data is transmitted, the switch selects a constituent signal forming a differential signal output from a receiver. When bidirectional communication is performed using only the CEC line, the switching control unit controls the switch so that the CEC signal output from the HDMI (R) source or the receiver is selected. The present invention is applicable to, for example, HDMI (R).
