Abstract
Method and device for a wired communication link that includes a first transceiver that sends over a set of wires a downstream multiplexed transmission that includes a first direction of a bidirectional data channel and lossless high definition digital video. The first transceiver is able to receive, over at least a subset of the set of wires utilized for the downstream multiplexed transmission, an upstream transmission comprising a second direction of the bidirectional data channel.
Claims14
A wired communication link comprising:
- a first transceiver configured to send to a second transceiver, over a set of wires, a downstream multiplexed transmission comprising a first direction of a bidirectional data channel and lossless high definition digital video comprising:
- video pixel data, video clock related data, and video synchronization data;
- the first transceiver is further configured to receive from the second transceiver, over at least a subset of the set of wires utilized for the downstream multiplexed transmission, an upstream transmission comprising a second direction of the bidirectional data channel;
- and
- the second transceiver is configured to receive the downstream multiplexed transmission and regenerate video timing of the lossless high definition digital video based on:
- the video clock related data, and order of receiving the video pixel data and the video synchronization data.

A method comprising:
- sending, by a first transceiver to a second transceiver over a set of wires, a downstream multiplexed transmission comprising:
- a first direction of a bidirectional data channel and lossless high definition digital video comprising:
- video pixel data, video clock related data, and video synchronization data;
- receiving, by the first transceiver from the second transceiver over at least a subset of the set of wires utilized for sending the downstream multiplexed transmission, an upstream transmission comprising a second direction of the bidirectional data channel;

- and
- regenerating, by the second transceiver, video timing of the lossless high definition digital video based on:
- the video clock related data, and order of receiving the video pixel data and the video synchronization data.
