Abstract

A system is disclosed for extending the effective operational range of an infrared remote control system. The infrared remote control system is of the type having a remote control unit with a housing defining an interior component compartment. An infrared transmitter is at least partially contained within the component compartment while the controlled device includes an infrared receiver. The extender system includes a first repeater which is contained within the component compartment closely adjacent the infrared transmitter. An infrared receiver is contained within the first repeater and generates an output signal representative of the infrared signal received from the remote control unit. A radio transmitter at the first repeater then transmits a radio signal to a radio receiver at a second repeater which is physically adjacent the controlled device or devices. The radio receiver generates a second electrical signal representative of the received radio signal and this second electrical signal activates an infrared transmitter which transmits an infrared signal to the controlled device.
