IP multiplexer is developed with independent intellectual property rights embedded digital image communication products, is an advanced digital broadcast television system with IP input, TS stream re-multiplexing, scrambling, IP output devices, based on PID packet switching technology, can multiplexing, scrambling the multi-channel digital TS stream input signals, analyzing the input MPTS, and added to the output stream EPG (Electronic Program Guide), CA (Conditional Access) and a data broadcast information. It can automatically generate SI / PSI information, with the program (Service) and PID filtering and re-multiplexing capabilities, in order to achieve EPG and data broadcasting value-added services. Each module SFP / GE ports supports 256 different IP address and port number input. Output can be set to 16/32 channel multiplexing, scrambling multi-program (MPTS) program transport stream UDP packets, and provide IP source to each sub-headend. Output can also be set to output 256 single program (SPTS) IP transport stream packet (total rate ≤800Mbps), and provide IP source to IPTV system. It can meet the need of different digital TV headend system.

*Support unicast or multicast, support IGMP v2\v3 protocol;

*Support high speed IP data receiving, GE port transfer bit rate up to 800Mbps；

*Support 1-4 ASI BNC interface input (can set input interface quantity), or 1-4 ASI BNC interface output (can set output interface quantity)*Support MPEG-2/MPEG-4 re- multiplexing, SPTS(single program stream) or MPTS (multi-programs stream);

*IP input, RJ45 port or SFP interface, GE port support 256 IP input, SPTS (single program stream) or MPTS (multi programs stream)

*Support PID pass through, re-mapping, each multiplexing channel can re-mapping 256 PID;

*Support 4 CAS simulcrypt, support DVB common scrambling system (ETR289), simulcrypt standard ETSI 101 197 and ETSI 103 197;

*Support IP output optional 256 signal program (SPTS) streaming IP package (total bit rate≤800Mbps) or 16/32 channels multiplexing or scrambling TS stream IP package,

*Support IP output empty package filtering function;

*With large cache design, IP data interface supports burst and uniform input stream, and the implementation of a uniform code for the stream reforming, improving the efficiency of the output stream;
