The series of cutpoints is determined by a pseudo-random sequence. Channels were decoded using a pseudorandom number generator (PRNG) sequence stored on a smart card (aka Viewing Card). To decode a channel the decoder would read the smart card to check if the card is authorised for the specific channel. If not, a message would appear on screen.
An analog Nagravision system (Syster) for scrambling analog satellite television programs was used in the 1990s.In this line-shuffling system, bottom 32 lines of the PAL TV signal are shifted in time by one video field, and read out in permuted order under the control of a pseudorandom number generator.
VideoGuard (sometimes referred to simply as NDS), produced by NDS, is a digital encryption system for use with conditional access television broadcasting. It is used on digital satellite television systems – some of which are operated by News Corporation, which owned about half (49%) of NDS until its sale to Cisco in 2012 (becoming Cisco Videoscape division).
