TELEVISION ACCESS CONTROL SYSTEM

摘要

An arrangement for the control of viewing of a video/television program in which a rating code and a position code are transmitted with the video/television signal. The codes are decoded and processed via a microcontroller. A viewer of the video signal is able to enter codes of permitted program ratings using a remote control unit. The rating codes are based upon the content of the video signal. The position codes relate to the display position of possibly objectionable content. Based upon a comparison of the received codes and the permitted program ratings portions of video signal are blanked and/or muted. The position codes allow for sub-portions of the image display to be blocked rather than the entire display.
