CATV Headend Scrambler

Overview:

  TS Stand alone 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 synchronous

controller send control word and access conditions and exchange information with ECMG. Co-ordination with the CA

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

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

used in digital television scrambling.
