Descramble in Cable television context is the act of taking a scrambled or encrypted Video Signal one that has been processed by a scrambler and provided by a Cable Television company for Premium television services and is then supplied over a Coaxial cable and delivered to the household where a Set-top box reprocesses the signal, thus descrambling it making it available for viewing on the Television set. A descrambler is a device that restores the picture and sound of a scrambled channel. A descrambler must be used with a Cable converter box to be able to unencrypt all the premium & pay-per-view channels of a Cable Television System.
