ABSTRACT:
An embodiment of the present invention is a method for programming a controller for selection, from a plurality a set of infra red (IR) codes, set of IR codes for subsequent control of IR signal communication with a video cassette recorder (VCR). Each set of IR codes is for communicating with a different corresponding VCR. To this end, each such VCR has a tuner, which, when tuned to an actual channel of broadcast video signals, provides video signals derived from the actual channel to a video output thereof. A signal is provided to the VCR where the signal is predetermined by a selected IR code which is selected from one of the sets of IR codes. This causes the VCR to perform a predetermined operation. The video output of the VCR is monitored for a predetermined signal condition, such as a video signal being present, or for a label broadcast in the video signals. A set of IR codes is then selected for subsequent signal communication with the VCR. The set of IR codes which is selected is the one from which the selected IR code is selected which results in the predetermined signal condition.
