Overview:

SC-3102 scrambler Modulator aims to DVB simulcrypt scrambling on input code 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 code stream. then send stream to

qam module ,make RS codes, convolution interleaving and QAM modulation channel processing, RF output.

Use a new generation of integrated circuits BCM3034, low-power, high index.
