PROBLEM TO BE SOLVED: To realize a stiff TS demultiplex processing, even with respect to a transmission fault or a reception fault. SOLUTION: Even when a version number is revised, the receiver acquires a desired packet that includes an ID to specify whether or not the packet is to be acquired and a version number that is revised from an MPEG2-TS whenever time contents of the packet are revised. In this case, a pattern match filter 24 extracts the packet, when the pattern match filter 24 detects matching of a pattern of the ID from the TS. A pattern unmatching filter 25 extracts the packet, when the filter 25 detects that a version number included in the packet extracted by the filter 24 differs from the version number monitored at present. A CPU8 acquires the packet, when the filter 25 extracts the desired packet and uses the version number monitored next to be a newly detected version number. |
