COL52122C EIT multiplexer is an enhanced TS multiplexer with EIT multiplexing function for digital TV broadcasting head-end system. EIT multiplexer has all the functions of normal TS multiplexer, including program multiplexing, PSI/SI editing, etc. It has 12 ASI input ports, 2 two separate ASI output ports and 2 gigabits IP output ports. Different from normal TS multiplexer, EIT multiplexer can not only multiplex programs' video, audio, PCR PIDs, but also multiplex the PIDs of program’s EIT table (event information table). When user selects the needed programs and give them to the output, The EIT table PIDs will automatically go to the output together with the programs' PIDs such as video, audio, PCR, ect. EIT table is the core part of EPG system of Digital TV Broadcasting. In Comparison with normal EPG system architecture, this facility largely gives the convenience to users who want to have EPG service to their Digital Head-end System. It doesn’t require EPG server, EPG Database, and day after day painstaking Database maintenance. The reason is most of TS from satellite has related EIT table (EPG information) already.
