Abstract

A high definition video transmitter and receiver are disclosed. The transmitter provides high definition video to a one-point receiver or to multipoint receivers. The transmission network is asynchronous and the receiver re-synchronizes the video. The transmission can be wired or wireless.

Claims

1. A point to multipoint transmitter for community High Definition Media Interface:

(HDMI) signal output to active ones of multiple receivers, the transmitter communicating with an appliance providing the transmitter with Consumer Electronic Control lines wherein the transmitter establishes itself as a Consumer Electronic Control root device and intercedes to prevent the Consumer Electronic Control lines from directly connecting to the HDMI signal output except through the transmitter.

2. A point to multipoint transmitter according to claim 1, wherein the transmitter generates a physical address for each Consumer Electronic Control appliance connected to the transmitter.

3. A point to multipoint transmitter according to claim 2, wherein the transmitter generates the physical address by appending a port number of the transmitter onto a physical address of the transmitter and placing that value in the Extended Display Identification Data (EDID) of the port.
