asi scrambler 

Overview:

  TS Stand alone simulcrypt scrambler aims to DVB simulcrypt scrambling on input transport streams, embedded control

generator,can send fixed or variable control word scrambling focus on transport stream; scrambling machine inside

synchronouscontroller send control word and access conditions and exchange information with ECMG. Co-ordination with

the CAsystems, through the rational control of scrambling cycles (CP), scrambling machine aims to facilitate the proper

decoderto decrypt control word, descrambling transport stream. Scrambling machine is a highly integrated device, which

is mainlyused in digital television scrambling.

Features:

  u 8 Mbytes caches, anti-burst stream;

  u 63 sets of programs can be scrambled, each program supports 32 elements;

  u 2 channel inputs, real-time hot backup;

  u Support EPG data insertion;
