Scrambler Standard Alone DVB System HEADEND for CAS

stand alone scrambler is applied in the simultcrypt scrambling of input code stream. It can send fixed or agile word scrambling  

Overview

DHD-801 stand alone scrambler is applied in the simultcrypt scrambling of input code stream. It can send fixed or agile word scrambling according to transport stream. The built-in simulcrypt synchronization controller transmits the exchange information with ECMG., When integrated with CA, the scrambler adjusts crypto period appropriately in order to make decoder function normally. This is a high integrated equipment for digital TV scramble.
