Description
A method and apparatus for securing a television transmission signal from unauthorized reception is disclosed that employs a sideband interdiction technique. A portion of the signal’s sideband content is enhanced such that the signal is rendered useless for reception. The signal is decoded by passing the signal through a passive all-pass delay-equalizer network at the site of the receiver.
The Eagle SIS-3001 Sideband Interdiction System is a state of the art Positive Scrambling Headend device intended to encode a TV channel for transmission down a standard CATV system
