Abstract:
1. A method for decoding an MPEG picture stream, comprising: inputting an MPEG picture stream formed by an intra picture and a predictive coded picture; providing an instruction to start decoding said MPEG picture stream; decoding each of said pictures of said input MPEG picture stream to produce a decoding result after said instruction to start decoding has been provided; temporarily storing said decoding result; storing said decoding result in a picture memory after the temporary storage; and obtaining output picture data from said picture memory; wherein, when said predictive coded picture includes an intra slice or an intra macroblock, said decoding step includes decoding said intra slice or said intra macroblock after said step of providing said instruction to start decoding without waiting for said intra picture to be decoded.
