Patent ID: 7835382

Claim:
A communication link comprising: a cable containing four pairs of wires, three transmitters, three receivers, and two transceivers; the three transmitters operative to transmit uncompressed video data and data over three of the pairs of wires to the three receivers; the two transceivers operative to form a bidirectional multi data type communication link over the fourth pair of the pairs of wires; an active mode of operation for transmitting the uncompressed video data over the three pairs of wires from the three transmitters to the three receivers, and for transmitting bidirectional system control data, bidirectional general data, and audio data over the fourth pair of wires between the two transceivers; and a low-power partial-functionality (LPPF) mode of operation for transmitting over the fourth pair of wires a subset of the data types transmitted in the active mode of operation over the fourth pair of wires.
