WDH-1520TP is a professional broadcast level Twin DVB-TS Scrambler module,which can support 2 TS streams scrambling with one signal unit. Each ASI Out ports can output independent scrambled TS streams or transparent loop through input TS stream out. It can support up to four different Simulcrypt scramble or BISS 1/E scramble by using the DVB common scrambling algorithm and built-in CW generator. With its high performance and stability, WDH-1520TP can be widely used in current or new-style DVB-S/T/C digital TV headend system.
