US 2006/0215711 A1 · Apparatus for receiving packet stream

Abstract

In the packet stream receiver, transport streams are sequentially input, discontinuity of continuity counters described in packet headers of transport stream packets in the stream is detected and a loss of a transport stream packet is determined. A terminator is added to part of NAL units extracted from a packet immediately before the transport stream packet is lost, and data on NAL units up to a NAL unit whose start code is detected is discarded after the start code of the NAL unit contained in the transport stream packet is detected and a terminator is added thereto. Thus, a packet stream receiver can obtain appropriate data even when part of packets is lost during transmission.

Dependent claims

An apparatus for receiving a transport packet stream, comprising:

an input unit configured to sequentially inputs transport stream packets constituting the transport packet stream;
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;
a termination processor configured to add a terminator to part of an elementary stream extracted from a transport stream packet immediately before the transport stream packet is lost;
and
a detection processor configured to detect a synchronize point of the elementary stream after adding the terminator, and discard data of another part of elementary stream between the terminator and the synchronize point of the elementary steam.
