Patent Images

1. , for a computer implemented method for video image decoding in the video image compression system with decoder, described method comprises:

  • There is provided the encoded bit stream of the frame with image-region, described frame has bi-directional predicted frames and can reference frame;

    AndCan decode by the image-region of reference frame at least one bi-directional predicted frames by reference to two or more in described bit stream, wherein said decoding comprises the motion vector using convergent-divergent, the motion vector of described convergent-divergent be by by frame scale fraction application in two or morely can the motion vector in selected digital image region of reference frame obtaining from described, wherein said frame representative fraction two or morely can be derived by the relative position of each in reference frame relative to described based at least one bi-directional predicted frames describedEach in wherein said frame comprises arrangement pixel value in a macroblock.
