In a demultiplexer, if as for a certain packet a packet header detection section has detected a packet header without error, a memory control section controls a payload of the packet which is separated by a payload separation section to be stored in a buffer memory. If, as for a predetermined number of packets, the packet header detection section has detected packet headers without error, the memory control section permits a payload of a packet previous to the predetermined number of packets to be output from the buffer memory.

Demultiplexer

In a demultiplexer, a finite search length and a finite jump length are set in a packet header detection section. The packet header detection section skips from a transfer start position of a multiplexed stream according to the set jump length and then searches for a start code included in a packet header which is to be detected through a range designated by the search length. A payload separation section separates payloads included in the multiplexed stream based on detection results of the packet header detection section.
