ABSTRACT:
Remote control code filtering techniques are disclosed that are suitable for use in a remote control code relaying system. A portion of a received remote control code is compared with corresponding portions of stored remote control codes. The received remote control code can be filtered based on the comparison. The filtering can comprise outputting the received remote control code or a portion thereof, discarding the received remote control code, or adding a new remote control code to the stored remote control codes. The remote control code can be received from a network or from a hardware interface (e.g., which converts an electromagnetic remote control signal to the remote control code). The received remote control code can be output to a network or to a hardware interface for subsequent transmission of an electromagnetic remote control signal. Filtering can occur before or after the network.
