Classification: H04L,H04N

Abstract:
A picture processing system for processing a transport stream including a plurality of groups of packets and a splicing point for separating each two of said groups, each of said groups having payload data in respective said packets and a packet identification data (PID) for each of said groups, said picture processing system comprising a PID data storage section for storing a series of PID values corresponding to groups of packets to be processed, a next PID register for storing a next PID value corresponding to a next group of said packets, a present PID register for storing a present PID value corresponding to a present group of said packets to be processed, and a header processor for receiving said transport stream to output said payload data of packets each having a PID value which coincides with the present PID value, said header processor detecting said splicing point to output a PID switching signal, said next PID register responding to said PID switching signal to replace said next PID value with a following PID value following to said next PID value stored in said PID data storage section, said present PID register responding to said PID switching signal to replace said present PID value with said next PID value stored in said next PID register.
