ABSTRACT:
A remote control receiver which can be "taught" to recognize a remote control signal from any of a plurality of remote control receivers as its control signal. For this purpose, the transmitting code and the carrier of a remote control signal are analyzed and the transmitting code is stored in connection with the instruction content during a learning mode. Then, during normal operation, a received remote control signal is filtered by a band pass filter in which the filter band is set in accordance with the carrier of the remote control signal stored during the learning mode. The filtered signal is then decrypted with reference to the stored transmitting code, thereby permitting receipt of the remote control signal transmitted from a heterogeneous remote control transmitter. In this manner, the remote control receiver may be "taught" to respond to commands from a remote control transmitter the user is accustomed to using.
