1. one kind is used for the digit broadcasting receiver of reception by the dual transmission stream of digital broadcast transmitter transmission, comprising:

  • Demodulator, detect synchronizing signal synchronous of the baseband signal be additional to dual transmission stream TS, if receive the double T S that comprises common data stream and turbo data flow, demodulator carries out demodulation to turbo data flow and common data stream;

    Equalizer, carry out equilibrium and compensation for multi-path channel distortion to double T S;

    Processor, process turbo data flow and the common data stream of double T S, and recover turbo data flow and common data stream,Wherein, digital broadcast transmitter compresses common data stream and turbo data flow with different compressed format, and described processor comprises for the treatment of the first processor with recovering common data stream with for the treatment of the second processor with recovering the turbo data flow,Wherein, with format compression turbo data flow H.264,Wherein, the second processor comprises the turbo decoder, and this turbo decoder carries out the turbo decoding to the turbo data flow, and in the turbo decoding, while completing, the turbo data flow is turned back to dual transmission stream.
