20130183045 | COMMUNICATION CABLE APPARATUS INCLUDING SWITCH TURNED OFF IN REVERSE CONNECTION STATE OF COMMUNICATION CABLE APPARATUS - A switch is inserted and connected between a first portion and a second portion of an HPD line. The switch connects the first portion to the second portion when an HPD signal is outputted to the second portion. The switch cuts off the connection between the first portion and the second portion when the HPD signal is not outputted to the second portion. An AND gate generates a connection state detection signal that represents the connection state of an HDMI optical active cable, and outputs the connection state detection signal to a switch. | 07-18-2013 |
