Abstract:
1. An apparatus for receiving a transport packet stream, comprising: an input unit configured to sequentially input transport stream packets constituting the transport packet stream, wherein each transport stream packet has a header which includes an error indicator indicating whether an error is contained in the transport stream packet; a determining unit configured to detect discontinuity of continuity counters described in packet headers of the transport stream packets and determine a loss of a transport stream packet in the transport packet stream; a termination processor configured to add a terminator to an end of a remaining part of an elementary stream extracted from a transport stream packet immediately before the transport stream packet is lost, if the error indicator indicates error absence; a detection processor configured to detect a synchronize point of the elementary stream after adding the terminator, and discard data of the elementary stream between the terminator and the synchronize point of the elementary steam; and a decoder which decodes the data of the elementary stream including no discarded data.
