ABSTRACT:
Programmable television receiver controllers which may be manually programmed by a user to select or to limit the viewing selections for random times, typically in one-half hour intervals, throughout a predetermined time period such as a one week time period. Program selections may be made by setting suitable controls for the day, AM or PM, the half hour of the day and the channel desired, and entered into a memory by a push-button control. Thereafter a digital control clock automatically selects the pre-entered information at the appropriate times and provides a control signal which may be used to automatically select the identified channels to the exclusion of all others. Alternatively, the signal may be used to exclude the selected channel from selection manually. In one embodiment, the programmable controller is incorporated in the original design of the television receiver and in a second embodiment, an external controller is disclosed which can be attached to the antenna terminals of a conventional television. Additional embodiments include means for controlling other functions such as the ON-OFF function of the receiver.
