Outline
NDS3712 Tuner Mux-scrambler is the latest demodulation, multiplexing and scrambling device for digital TV broadcasting head-end system. The tuner mux-scrambler has maximum 6 channels tuner input (tuner can be DVB-S/DVB-S2) and 2 channels ASI input, while it has 2 groups of ASI output and 2 corresponding IP output (share one megabits DATA port). It can multiplex and encrypt the FTA stream to output. In other words, one tuner mux-scrambler can work as 6 standalone FTA IRD, one two separate ASI output multiplexer and two scrambler. In conclusion, its high integration and cost effective design make this device widely used in the Next Generation of CATV Broadcasting system.
