Product Main


JXDH-6602 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 highly integrated equipment for digital TV scramble.
