摘要:
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.
