COL***2B Multiplexer with scrambler

Outline 
Mux-scrambler is the latest demodulation, multiplexing and scrambling device for digital TV broadcasting head-end system. This mux-scrambler has maximum 8 channels , 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 conclusion, its high integration and cost effective design make this device widely used in the Next Generation of CATV Broadcasting system.
