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.
