ABSTRACT:
A system for encoding or scrambling a television signal and for subsequently decoding or unscrambling the signal for presentation on the viewing screen of a television receiver. Encoding is achieved by suppressing the amplitude and changing the phase of the television signal carrier during selected horizontal blanking intervals. Decoding is achieved by synchronously detecting the horizontal blanking intervals of a received signal having a suppressed amplitude and changed carrier phase and restoring the original relative characteristics of the television signal during the detected intervals.
