Patent ID: 7561622

Claim:
A video analyzer for analyzing encoded information included in an encoded video signal conforming to the MPEG (Moving Picture Experts Group) standard, the analyzer comprising: an input part for inputting the encoded video signal; an extracting part for extracting the encoded information; an analyzing part for analyzing the extracted encoded information; a decoding part for decoding the input encoded video signal; a delaying part for delaying transmission of the encoded video signal to the decoding part based on analysis processing time of the encoded video signal; and a multiplexing part for multiplexing the analyzed encoded information and the decoded video signal, wherein the analyzing part comprises a plurality of analyzing units which allows analyzing in parallel and a plurality of memories which allows buffering encoded video signals for one picture corresponding to the plurality of analyzing units, and the delaying part counts, using processing time in the encoded information analyzing part as a reference time, the number of packets arriving within the reference time period, and delays only the number of the packets corresponding to the reference time.
