This invention relates to a method for selecting and segmenting information in a macroblock and puts forward a segment method for quickly determining macroblocks to object edge information utilizing the property that man-eye is sensitive to object edge information including: 1, pre-segmenting a macroblock and dividing it according to if the edge information is contained in the macroblock to get blocks with edge information, 2, carrying out trial motion estimation to the segmentable blocks containing edge information to carry out the next stage segment to the block with the SAD not less than the preset value including pre-judging edge pixel points, if the segment can't go on any more, then it is decided they are the final sub-blocks, if it is segmented again, then the trial motion estimation is done to the block again to repeat the above mentioned step till the total segment to the entire block.
