发明名称 Method of transcoding data from the MPEG2 standard to an MPEG4 standard
摘要 The method is characterized in that, if the data relating to a first macroblock indicates that it is coded in frame prediction and field DCT mode, it comprises the following steps: - determination of the second macroblock (3, 4) in the image which, with the first (3, 4), forms a supermacroblock, each of the macroblocks having an associated MPEG2 inter-frame motion vector, V 0 and V 1 , - structuring of the macroblock (3, 4) in field mode (5, 6) and calculation of a partitioning (18, 19, 20, 21, 22, 23) of this supermacroblock according to the MPEG2 motion vectors V 0 and V 1 , - calculation of the motion vectors for each of the partitions according to the MPEG2 motion vectors V 0 and V 1 .
