Abstract

A method and apparatus are provided for determining the channel of a plurality of predetermined channels to which a remotely controlled receiver is tuned. A first transmitter device includes a keyboard for receiving viewer entered selections and transmits infrared or ultrasonic control signals for each of the viewer tuning and ON/OFF selections. A receiver device receives the transmitted control signal from the first transmitter and applies the received signal to a processor device that performs a stored program to identify the channel to which the monitored receiver is tuned. An associated memory device is used for storing the identified channel reception data. The processor device identifies the user selection and applies a corresponding second control signal to a second transmitter device. The second transmitted control signals have a predetermined format of the existing remote control receiver of the monitored receiver that is different than a predetermined format of the control signals of the first transmitter device.
