Abstract
A video viewing control system which permits the parent to enter a viewing 'allowance' (time) for each child and which disables viewing of a television by disrupting the television's Radio Frequency (RF) input signal or video input signal when the child has watched television for his allowable time. The system includes a single chip microprocessor and a liquid crystal display which permits display of graphical symbols to the child for easy comprehension. The system is battery powered to protect against power outages. The child's viewing time can be set on a daily basis (potentially different for each day of the week) or can be done on a weekly basis (a lump-sum covering the entire week). Block out times (during which television viewing is disabled) can be programmed for each child on the hour and half-hour for any day of the week. The system calculates and displays each child's average viewing time per day and the total viewing time over any desired period.
