METHOD AND APPARATUS FOR DETERMINING CHANNEL RECEPTION OF A RECEIVER Abstract of the Disclosure A method and apparatus are provided for de- termining 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 de- vice 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 stor- ing the identified channel reception data. The proces- sor device identifies the user selection and applies a corresponding second control signal to a second trans- mitter device. The second transmitted control signals have a predetermined format of the existing remote con- trol receiver of the monitored receiver that is differ- ent than a predetermined format of the control signals of the first transmitter device.
