It is possible to provide a communication system, a transmission device, a reception device, a communication method, a program, and a communication cable which enable a high-speed bidirectional communication while maintaining compatibility. When an HDMI(R) source (71) and an HDMI (R) sync (72) perform a bidirectional IP communication by using a CEC line (84) and a signal line (141), a switching control unit (121) controls a switch (133) so that the switch (133) selects a partial signal constituting a differential signal from a conversion unit (131) upon data transmission and a partial signal constituting a differential signal from a receiver (82) upon data reception. When a bidirectional communication is performed by using only the CEC line (84), the switching control unit (121) controls the switch (133) so that the switch (133) selects a CEC signal from the HDMI(R) source (71) or the receiver (82). The present invention may be applied, for example, to the HDMI(R). |
