Communication system, transmitter, receiver, communication method, program, and communication cable
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).
