Off premises cable television interdiction apparatus (130) comprises a microprocessor actuation and control means (300) for actuating and controlling at least one frequency agile voltage controlled oscillator (341-344). The voltage controlled oscillator (341-344) selectively jams only unauthorized premium programming transmitted in the clear from a headend (100) to a particular subscriber. The voltage controlled oscillator (341-344) generates a jamming signal carrier at a frequency 1/N between the video and audio carriers where N is an integer, preferably small. The microprocessor (300) provides a calibration mode and a normal mode of operation. During the normal mode of operation, a frequency hopping rate on the order of four thousand hertz is achievable. The method of interdiction comprises the steps of generating and storing voltage control words for operating the oscillator consistent with a headend selected jamming factor for a particular channel to be jammed and addressably transmitted and stored premium programming authorization data.
