A scrambled channel featuring a Paramount Pictures film (Possibly VideoCipher II or Oak ORION. Horizontal and vertical synch signal have been replaced by digital data with the effect that the picture is not properly displayed on the TV screen. [1] [2] [3]) as viewed without a decoder.
A scrambler (or randomizer) can be either: An algorithm that converts an input string into a seemingly random output string of the same length (e.g., by pseudo-randomly selecting bits to invert), thus avoiding long sequences of bits of the same value; in this context, a randomizer is also referred to as a scrambler.
All of Malta's national and political party channels are available free-to-air.

Channels scrambled (encrypted) with VideoCipher and VideoCipher II could be defeated, and there was a black market for illegal descramblers. By the end of 1987, 16 channels had employed encryption with another 7 planned in the first half of 1988. Packages that offered reduced rates for channels in bulk had begun to appear.
However, as all operations are on 8-bit subblocks, the algorithm can be implemented using regular SIMD, or a form of “byteslicing”. As most SIMD instruction sets, (with the exception of AVX2 ) do not support parallel look-up tables, the S-box lookups are done in a non-bytesliced implementation, but their integration into the rest of the ...

A descrambler is a device that unscrambles the encoded signal and restores the picture and sound of a scrambled channel. Typical modern cable boxes include some form of descrambling ability. Such a cable box must also be addressable (see below) in order to be told to descramble the signal for a given channel.
