2.2 Operating principle
AD2700 TS REMULTIPLEXER multiplex 2~8 MPEG-2 SPTS or MPTS into 1 MPTS, the null
packet or needless packet will be filtered. The PID could be reset if necessary and pick-up the relevant
information for further processing.
The processed program specific information (PSI) and service information (SI) is integrated with local
data. Each input consists of SPTS, each program includes video
、
