| 摘要 |
<p>The present invention is related to a communication system, a transmitting device, a receiving device, a communication method, a program and a communication cable that can be configured to carry out high speed bidirectional communication while maintaining compatibility. In the case where an HDMI(R) source (71) and an HDMI(R) sync (72) carry out bidirectional IP communication through a CEC line (84) and a signal line (141), a changeover control unit (121) controls a switch (133) so that a partial signal that composes a differential signal from a converting unit (131) is selected through the switch (133) at data transmitting time and so that a partial signal that composes a differential signal from a receiver (82) is selected at data transmitting time. In the case where bidirectional IP communication is carried out only through the CEC line (84), the changeover control unit (121) controls the switch (133) so that a CEC signal from the HDMI(R) source (71) or the receiver (82) is selected through the switch (133). The present invention can be applied to an HDMI(R), for instance. ® KIPO & WIPO 2009</p> |
