Patent ID: 7386051

Claim:
A digital broadcast receiving apparatus for receiving a digital broadcast signal, comprising: a digital front end operable to select a desired transmission channel from the received digital broadcast signal and to demodulate a transport stream transmitted by said desired transmission channel; a demultiplexer operable to extract a transport stream of a desired program from said demodulated transport stream, said extracted transport stream including a plurality of MPEG pictures; a decoder operable to decode each of a plurality of MPEG pictures of said extracted transport stream to produce a decoding result; a CPU operable to instruct said decoder to start decoding; and a receiving buffer operable to temporarily store said decoding result; a picture memory operable to store said decoding result after storage in the receiving buffer; wherein said plurality of MPEG pictures are formed by an intra picture and a predictive coded picture, and when said predictive coded picture includes an intra slice or an intra macroblock, said decoder decodes said intra slice or said intra macroblock after being instructed to start decoding by said CPU without waiting for said intra picture to be decoded.
