COMMUNICATION SYSTEM, TRANSMITTER, RECEIVER, COMMUNICATION METHOD, PROGRAM, AND COMMUNICATION CABLE Abstract 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 (71) performs bidirectional IP communication with an HDMI (R) sink (72) using a CEC line (84) and a signal line (141), a switching control unit (121) controls a switch (133) so that, when data is transmitted, the switch (133) selects a constituent signal forming a differential signal output from a converting unit (131) and, when data is transmitted, the switch (133) selects a constituent signal forming a differential signal output from a receiver (82). When bidirectional communication is performed using only the CEC line (84), the switching control unit (121) controls the switch (133) so that the CEC signal output from the HDMI (R) source (71) or the receiver (82) is selected. The present invention is applicable to, for example, HDMI (R). 6136736-1 |
