A transport packet parser ( 42 ) includes a transport packet header decoder ( 50 ) for identifying a packet identifier (PID) and continuity counter (CC) associated with a current packet. The PID along with an enable (En) bit is input to an PID associative memory ( 52 ) in search mode to identify an address associated with the PID. The address is used to access a CC associated with a previous packet for the same PID in a random access memory ( 62 ). The previous continuity counter is used along with other header information to determine whether the current packet satisfies predetermined criteria. If so, the packet is passed to a transport packet buffer for further processing.
