1. a kind of bit stream state determines method, it is characterised in that include:

  • The packet that signal source sends is received, the signal source code stream identification and the signal included in the packet is extractedThe PES/ES characteristic values of source code stream, the PES/ES characteristic values at least include one below:

    PES frame lengths, gop structure, MBType and timing code;

    Code stream corresponding with the signal source code stream identification is searched from the code stream for having received, the code stream for finding is madeFor target code stream;

    Extract the PES/ES characteristic values of the target code stream;

    Whether the PES/ES characteristic values for comparing the target code stream are consistent with the PES/ES characteristic values of the signal source code stream;

    If consistent, determine that the transmitting procedure of the target code stream is normal.
