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 in the image which, with the first, forms a supermacroblock, each of the macroblocks having an associated MPEG2 inter-frame motion vector, V0 and V1, structuring of the macroblock in field mode and calculation of a partitioning of this supermacroblock according to the MPEG2 motion vectors V0 and V1, calculation of the motion vectors for each of the partitions according to the MPEG2 motion vectors V0 and V1.
