Remote control code filtering used for relaying of remote control codes
First Claim
1. A method for filtering remote control codes in a remote control code relaying system, the method comprising the steps of:
- receiving a remote control code;
comparing a portion of the received remote control code with a corresponding portion of a given one of one or more stored remote control codes; and
filtering the received remote control code based on the comparison and 10 frequency information;
the step of comparing further comprises the step of comparing the portion of the received remote control code with a corresponding portion of each of the one or more stored remote control codes and determining there is no match between the portion of the received remote control code and a corresponding portion of each of the one or more stored remote control codes; and
the step of filtering the received remote control code based on the comparison further comprises the steps of;
determining whether the remote control code should be output or discarded; and
adding the new remote control code to the one or more stored remote control codes based on the determination of whether the remote control code should be output or discarded.

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.
