发明名称 ELECTRONIC EQUIPMENT, CONTROL INFORMATION TRANSMISSION AND RECEPTION METHODS HAVING BIDIRECTIONAL COMMUNICATION USING PREDETERMINED LINES
摘要 Electronic equipment and methods for permitting quick control of the operating state of a source equipment side from sink equipment. A television receiver (sink equipment) 100 and an amplifier (repeater equipment) 200 are interconnected over an HDMI cable 610, and the amplifier 200 and a DVD recorder (source equipment) 300 are interconnected over an HDMI cable 620. Each of the pieces of equipment includes, in addition to an HDMI receiving unit and an HDMI transmitting unit, a high-speed data line I/F included in a bidirectional communication unit that uses predetermined lines of the HDMI cable. The bidirectional communication unit is used to transmit channel selection information, a remote control code instructing recording, “theater mode” designating information, a remote control code, or the like from the television receiver 100 to the audio amplifier 200 or DVD recorder 300.
