Abstract

The transformation method for moving picture coding system reads data of a frame from the first data sequence in the first moving picture moving coding system, prereads a coding mode of a successive frame to record, and when the preread coding mode of the successive frame is the intra-frame coding mode, performs a control not to perform coding of a present frame or decrease a generated code amount corresponding to the generated coed content of the second data sequence in the second moving picture coding system. Then, the method preferentially transforms data coded by the intra-frame coding mode existing in the first data sequence to the second data sequence.
