Patent ID: 7062175

Claim:
A repeating radio frequency transmission system comprising: (a) a transmitter capable of being placed in signal communication with an infrared remote control, the transmitter comprising: (1) a detector configured to receive a first infrared control signal from the infrared remote control and generate a first electrical signal according to the first infrared control signal; (2) a buffer coupled with the detector to store at least a portion of the first electrical signal; (3) a first code register for storing a first identification signal; (4) a multiplexor for combining the first electrical signal and the first identification signal into a first augmented electrical signal; and (5) a radio frequency transmitter responsive to the first augmented electrical signal for transmitting a radio signal representative of the first augmented electrical signal; and (b) a receiver capable of being placed in infrared control signal communication with a controlled device, the receiver comprising: (1) a radio frequency receiver configured to receive the transmitted radio signal and for generating a second augmented electrical signal according to the received radio signal; (2) a second code register for storing a second identification signal; (3) a code detector for detecting the presence of the second identification signal within the second augmented electrical signal; (4) a second multiplexor in communication with the code detector for removing the second identification signal from the second augmented signal, leaving a second electronic signal; (5) an infrared emitter responsive to the second electronic signal for transmitting a second infrared control signal to the controlled device.
