CONDITIONAL ACCESS INFORMATION ARRANGEMENT

摘要

PROBLEM TO BE SOLVED: To provide a method of processing a packetized transport stream.

SOLUTION: The method includes steps of: determining a packet identifier for identifying transport packets associated with a selected program from a received packetized transport stream; programming a match detector to match with the packet identifier; analyzing the packetized transport stream using the programmed match detector; and specifying and capturing a desired sequence of transport packets in accordance with the packet identifier. The method further includes steps of detecting a counter section for providing count information which indicates an order of the transport packet associated with the selected program, in each transport packet, and determining whether a desired sequence of transport packets has been received in accordance with the order indicated in the counter section assigned to the received sequence of transport packets.
