A remote control transmitter and receiver for controlling all of the usual viewer-adjustable functions of a television receiver. A plurality of key/switches permit the viewer to select the channel to be tuned and the function to be controlled. Digital logic circuits generate pulse coded signals that identify channel members or controlled functions. Function level control pulses are generated by rotation of a code wheel connected to a thumb wheel to provide proportional control of selected functions. The pulse coded signals and function level control pulses are transmitted via an infrared optical link to the receiver where companion circuitry decodes the pulse coded signals and adjusts the levels of selected functions in response to the function level control pulses. |
