<p>A system as shown in the Figure for control of an electronic device (20) having an infrared sensor for receiving an infrared control signal from a remote control comprises an infrared sensor (14) for receiving and converting the infrared control signal from the remote control (18) to an electrical signal, the sensor being attached to an audio speaker assembly (12) of an audio reproduction system. A signal generator (24, 26) also attached to the speaker assembly is operatively connected to the sensor for generating an RF carrier signal modulated by control information encoded in the infrared control signal and the electrical signal. A transmission link (30) is provided for transmitting the modulated RF carrier signal from the speaker assembly to the electronic device (20). A signal receiver (36) disposed adjacent to the infrared sensor of the electronic device receives the modulated RF carrier signal and converts the modulated RF carrier signal to a secondary infrared signal (44) essentially identical to the infrared control signal.</p> |
