Patent Images
1. A system for the elimination of predetermined video/audio program information from broadcasted video/audio signals comprising, in combination:
- a video/audio signal source;
a video/audio signal;
a video/audio signal output normally connected to said video/audio source;
a switch to disconnect said output from said source;
and switch operation means to cause blanking of unwanted video/audio signal information from said video/audio signal output by providing the operation of said switch correlative to the information contained within said video/audio signal and wherein said switch operation means includes a video/audio signal sampling/conversion means for sampling a content of the video/audio signal, and converting the video/audio signal samples into data bits representing digital words;
a memory means adapted to store digital words therein;
programming means for storing selected digital words within said memory means;
a comparator means for comparing the output of said video/audio signal sampling means with said memory to obtain an enabling output from said comparator means when said digital words generated by said video/audio signal sampling/conversion means match;
transmitting means for routing said enabling output to, and operating, said switch.
