ABSTRACT:
A video signal processing system for producing an output signal suitable for coupling to a display device to produce a displayed image, the video processing system having a system which blocks viewing of programs which are broadcast with ratings or spending information which is outside a profile set by a supervisor who has entered a password accepted by the control system, and which permits the supervisor to temporarily modify the ratings profile according to a set of override parameters. After completion of the time period(s) or supervisor-designated television broadcast(s), the system automatically returns to the normal ratings profile but retains the set of override parameters for easy reimposition by the supervisor.
