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.
Features
* Fully complying with ISO13818 and EN300 468 standard
* Support 8 ASI input for re-multiplexing
* Support 64 IP input through DATA 1 and DATA 2 over UDP protocol
* Support accurate PCR adjusting/ PID re-mapping/PSI/SI rebuilding and editing
* Support 6 different simulcrypt (CAS ETR289, ETSI 101 197, ETSI 103 197)
* Two groups (each group has 2 channels)separate ASI outputs
* IP (2 MPTS) over UDP, RTP/RTSP output as mirror of ASI output (RJ45), GE Port, DATA 1 and DATA 2
* Huge buffer memory for saving the overflowing code stream
* Support to multiplex one program to all outputs
* LCD/keyboard and Web-based NMS management
