Abstract
To initialize a remote control device for use in a particular installation, initialization parameters are entered relating to the relationship between user input codes and equipment to be controlled. In the preferred embodiment involving video recorder equipment, the initialization procedure concerns the video channels available to the recorder and remote control codes associated with the operation of the recorder. Using a receive-only modem on the device attached to a phone jack, initialization is performed by dialing up a remote location with a touch tone phone. At the remote end a computer sends selected audio response signals to the telephone receiver requesting that the user key in information using the touch tone pad. The computer then transmits the appropriate signals to the memory of the remote device to initialize it.
