Abstract:
1. A method for processing a packetized transport stream, comprising the steps of: receiving a packetized transport stream comprising a plurality of transport packets; determining a packet identifier for identifying transport packets associated with a selected program; parsing the packetized transport stream to identify and capture a desired sequence of transport packets in response to the packet identifier; detecting, in each of the transport packets, the presence of a counter portion that provides count information indicative of sequential ordering of the associated transport packet, the counter portion comprising a field having a predetermined number of bits, which increments in sequence with each successive transport packet in the sequence of transport packets and wraps around to zero after a maximum value associated with the predetermined number of bits; determining whether a desired sequence of transport packets has been received in response to the sequence of counter portions associated with the received sequence of transport packets; detecting, in each of the transport packets, the presence of a one bit toggle portion that provides information indicative of an error in the associated transport packet; and determining whether an error exists in the associated transport packet in response to the one bit toggle portion.
