<p>A cable television interdiction apparatus (130) comprises a microprocessor actuation and control means (300) for actuating and controlling one or more frequency agile voltage controlled oscillators (341-344). The voltage controlled oscillators (341-344) selectively jam only unauthorized premium programming transmitted from a headend (100) to a particular subscriber. The method of interdiction comprises the steps of generating and storing voltage control words for operating the oscillators (341-344) consistent with a headend selected jamming factor for a particular channel to be jammed and addressably transmitted and stored premium programming authorization data.</p> |
