7. To support descrambling, the demultiplexer interfaces with the descrambler part of a conditional access system.

8. This paper presents a new type of TV signal scrambler and descrambler system witha high performance-to-cost ratio, great safety and no distortion and discusses its function, principle and realization.

9. While a few homebrew circuits were designed to allow people to tune these premium channels without needing a special descrambler box, this has remained pretty much unchanged over the years.
