Abstract
An auxiliary circuit for remote control of television receiver blanking (audio and video) by digital code words transmitted as part of the video signal. The circuit detects and decodes the transmitted code and depending upon the code received, blanks either or both the audio and video signals in the receiver. A selector switch would be interconnected with the digital decoder to permit selection of particular code words which will cause the circuit to blank. The selector switch will normally be available for the television viewer to control. The transmitter for transmitting the digital code in the preferred configuration would comply with FCC Rules and Regulations specifying program related ASCII transmissions on line 21 of picture field 1.
