Scrambling of the television signal in a CATV broadcasting system is effected by modulating the audio signal with a pilot signal, and modulating both the audio and video with a scrambling signal of a different frequency from the pilot signal. Descrambling is accomplished by detecting the pilot and scramble signals and using each in different ways to control demodulation so as to remove the scramble component from the audio and video signals.
