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.

Claims

1. A television viewing control system for monitoring and controlling the viewing time of a plurality of viewers watching a television set and disabling viewing when a predetermined viewing time has expired, said control system comprising:

(a) memory circuit means for semipermanently storing an assigned individual password for each of said viewers, a predetermined viewing time quota associated with each of said viewers, the portion of said viewing time quota remaining for each of said viewers, and blocked times for each of said viewers during which viewing is prohibited;

(b) a control means for actuating viewing of the television by switching an RF input signal or video input signal on and off;

(c) a display means for displaying information recorded in said memory circuit means;

said display means comprising a plurality of display elements for simultaneously displaying information recorded in said memory circuit means;

(d) processing means including;

(1) clock means for calculating the current time of day and the day of the week, and

(2) polling means for comparing an entered password to said assigned individual passwords to determine if said entered password is valid, and

(3) comparing means for comparing the predetermined blocked times to said current time of day to determine if viewing is blocked;

(4) monitor means for monitoring each viewer'"'"'s time remaining;

(5) accumulating means for accumulating each viewer'"'"'s total viewing hours;

(e) input means by which each of said viewers can enter their said assigned password, by which said viewers select information to be displayed and by which said memory circuit means can be programmed;

(f) means for selectively blocking designated television channels;

wherein said processing means is operably connected to said control means for selectively actuating or deactuating said RF in put signal or video input signal to said television set;

wherein said system enables the designation of different viewing time quotas for each of said viewers each day; and

wherein said system further comprises override means for controlling viewing of said television set independent of said control means.

2. A television control system as recited in claim 1 wherein said display means is adapted to display said current time of day, the day of the week, which viewer has activated viewing of the television, viewer'"'"'s viewing time quota, remaining viewing time quota, blocked times, total viewing time, average daily viewing time, daily or weekly.

3. A television control system as recited in claim 1 wherein said system further includes programming means enabling programming of each viewer'"'"'s, viewing time quota, blocked times and password.

4. A television control system in accordance with claim 1, wherein said system is contained in said television set in a manner such that said information recorded in said memory circuit means may be displayed on said television set.
