Abstract
A television tuning system includes a memory for storing tuning information with first and second groups of memory locations for storing different tuning information for the same group of predetermined channels. A mode switch, in a first mode, allows memory locations in the first group to be addressed when channels in the predetermined group are selected and in a second mode allows memory locations in the second group to be addressed when channels in the predetermined group are selected. Such an arrangement is useful in a motel, hotel or hospital to allow certain channels in a list of channels to be selected when a rental fee has been paid and to exclude those certain channels when the rental fee has not been paid.
