1. receiving system;

  • The transmission path of this receiving system utilization regulation receives signal;

    Wherein said signal for dispensing device one side will from the generation source source wraparound speech signal that send of regulation and each logic channel be divided into with matching a plurality of key element wraparound speech signals, also will be as a plurality of coding elements wraparound speech signals of cutting apart the result that each key element wraparound speech signal of obtaining encodes are housed in the signal that sends in unit of transfer'"'"'s signal;

    And carry out corresponding to the decode results of the coding elements wraparound speech signal that from unit of transfer'"'"'s signal, takes out, be the reproduction output of key element wraparound speech signal;

    It is characterized in that, be provided with;

    Hinder the event detection unit;

    Predetermined obstruction incident has taken place in the transmission course that is used for detecting on said transmission path;

    Wherein, this predetermined obstruction incident is meant that obstruction uses the incident of the coding elements wraparound speech signal in any one that is housed in the said unit of transfer signal that receives according to time series in reproducing output;

    AndPress the interpolating unit of the number setting of said logic channel;

    Be used for detecting under the situation that said predetermined obstruction incident has taken place in this obstruction event detection unit;

    Use the value in cycle shared in each key element wraparound speech signal;

    Generate in order to replacement and be contained in the replacement key element wraparound speech signal of the coding elements wraparound speech signal in this unit of transfer'"'"'s signal, and be inserted in the sequence of key element wraparound speech signalWherein, have as the 1st interpolating unit of one of said a plurality of interpolating unit with as the 2nd interpolating unit beyond the 1st interpolating unit one of said a plurality of interpolating unit, said by a plurality of interpolating unit of the number setting of said logic channel,Said the 1st interpolating unit possesses;

    The 1st key element wraparound speech signal storage part;

    Be used to store the key element wraparound speech signal, this key element wraparound speech signal is the decode results to the coding elements wraparound speech signal that extracts the unit of transfer'"'"'s signal that receives from the logic channel through correspondence;

    Computation of Period portion;

    Be used for according to the key element wraparound speech signal that is stored in said the 1st key element wraparound speech signal storage part;

    Calculate for same source wraparound speech signal is cut apart each key element wraparound speech signal of obtaining the value in shared cycle;

    Wherein, the value in this cycle is the value that becomes the formation base of said replacement key element wraparound speech signal;

    The 1st interpolation execution portion uses the value in the said cycle that calculates, and said replacement key element wraparound speech signal is inserted in the sequence of key element wraparound speech signal;

    Cycle notice portion, be used for the value in said cycle is notified to said the 2nd interpolating unit;

    AndThe 1st control part is controlled the action of the 1st interpolating unit,Said the 2nd interpolating unit possesses;

    The 2nd key element wraparound speech signal storage part;

    Be used to store the key element wraparound speech signal, this key element wraparound speech signal is the decode results to the coding elements wraparound speech signal that extracts the unit of transfer'"'"'s signal that receives from the logic channel through correspondence;

    Cycle is obtained portion, obtains the value in the said cycle of being notified from said cycle notice portion of said the 1st interpolating unit;

    The 2nd interpolation execution portion uses the value in the said cycle of being obtained, and said replacement key element wraparound speech signal is inserted in the sequence of key element wraparound speech signal;

    AndThe 2nd control part is controlled the action of the 2nd interpolating unit.
