Transmitting digital video and data over the same wires
First Claim
1. A communication device configured to transmit and receive simultaneously, over the same wire, unidirectional high definition video and bidirectional data, comprising:
- a hybrid circuit coupled to a cable made of wires;
a transceiver configured to transmit, over a wire comprised in the cable, Transition Minimized Differential Signaling (TMDS) data and source-to-sink direction of bidirectional data;
wherein the TMDS data comprises;
video pixel data, and horizontal and vertical video synchronization data; and
the transceiver is further configured to receive, over the same wire and simultaneously with the transmitting, opposite direction of the bidirectional data.

Abstract
A communication device configured to transmit and receive simultaneously, over the same wire, unidirectional high definition video and bidirectional data. The communication device includes a hybrid circuit coupled to a cable made of wires, and a transceiver. The transceiver is configured to transmit, over one of the cable'"'"'s wires, Transition Minimized Differential Signaling (TMDS) data and source-to-sink direction of bidirectional data. The transceiver is further configured to receive the opposite direction of the bidirectional data over the same wire and simultaneously with the transmitting.

12. A communication device configured to transfer simultaneous transmissions of a Transition Minimized Differential Signaling (TMDS) data and bidirectional data, comprising:
-
a hybrid circuit coupled to a cable made of wires; and a transceiver configured to transmit and receive, over the same wire simultaneously, the TMDS data and source-to-sink direction of the bidirectional data, and opposite direction of the bidirectional data;
wherein the TMDS data comprises;
video pixel data, and horizontal and vertical video synchronization data;the transceiver is further configured to modulate the source-to-sink direction of the bidirectional data using a first modulation; and the transceiver is further configured to modulate the TMDS data, which is also in the source-to-sink direction, using a second modulation; wherein the first modulation provides the source-to-sink direction of the bidirectional data a higher protection against noise compared to protection against noise provided to the source-to-sink direction of the TMDS data by the second modulation. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
