Desing NDS3712B Multiplexer Scrambler

Outline

NDS3712B multiplexer scrambler is the latest multiplexing and scrambling device for digital TV broadcasting head-end system. It can receive up to 8 ASI and 512 IP input and output TS after multiplexing and scrambling. There are 2 groups of separate ASI output port and GE ports for IP outputs. The multiplexer scrambler has all the functions of normal TS multiplexer, including programs multiplexing, PID re-mapping etc. Also the multiplexer can insert EPG (Electronic Program Guide), and data casting information into each output stream. In conclusion, its high integration and cost effective design make this device widely used in the CATV Broadcasting system.
