ABSTRACT:
A first data sequence generated by a first moving picture coding system having an intra-frame coding mode and an inter-frame coding mode is transformed to a second data sequence generated by a second moving picture coding system having an intra-frame coding mode and an inter-frame coding mode. The method includes prereading a coding mode of a successive frame succeeding a present frame from the first data sequence, judging whether or not a preread coding mode of the successive frame is the intra-frame coding mode and determining whether or not to code the present frame by the second moving picture coding system corresponding to a generated code amount of the second data sequence when the coding mode of the successive frame is the intra-frame coding mode. Data coded by the intra-frame coding mode existing in the first data sequence is transformed to the second data sequence.
