<p>In the packet stream receiver, transport streams are sequentially input, discontinuity of continuity counters (32) described in packet headers (14) of transport stream packers (16) in the stream is detected and a loss of a transport stream packet (16) is determined. A terminator (0x80) is added to part of NAL units extracted from a packet (16) immediately before the transport stream packet (16) 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 (16) is detected and a terminator (0x80) is added thereto. Thus, a packet stream receiver can obtain appropriate data even when part of packets is lost during transmission.</p> |
