Abstract
A wired communication port comprising a transmitter operative to transmit, over a set of wires, a first transmission comprising a digital video clock multiplexed with a first direction of a bidirectional data channel. The transmitter is further operative to transmit video pixel data and video synchronization data over the same set of wires. And a receiver operative to receive a second transmission comprising a second direction of the bidirectional data channel, over at least a subset of the set of wires utilized for the first transmission.
Claims64
A wired communication link comprising a first and a second transceiver;
- the first transceiver comprising a transmitter operative to transmit, over a set of wires, a first multiplexed transmission comprising a first direction of a bidirectional data channel and lossless high definition digital video comprising pixel data, video clock related data, and video synchronization data;
