Abstract

A cable-ready television set having a controller with first and second sets of leads for scanning a plurality of push-button switches and, in response to actuation of the switches, entering into a tuner memory designations defining which channels may be selected for viewing and which channels may not be selected, is modified by disconnecting the switches and connecting the first and second sets of leads to a first connector accessible from the exterior of the set. A hand-held programming module includes a plurality of programming switches connected to a second connector so that each programming switch is connected between one lead in each of the first and second sets of leads when the connectors are mated. The hand-held module includes a non-volatile memory for storing tier data and a microprocessor responsive to actuation of tier selection switches on the module for applying the tier data to the programming switches. Actuation of the programming switches causes the tuner controller to load the tuner memory with designations indicating which channels may or may not be viewed.
