METHOD AND DEVICE FOR CODING/DECODING OF MOTION VECTOR Russian patent published in 2013 - IPC H04N7/32 

FIELD: information technologies.

SUBSTANCE: method for motion vector coding includes the following stages: selection of the first mode as the mode of information coding about a predictor of the motion vector in the current unit, and in this mode information is coded, which indicates the motion vector predictor at least from one motion vector predictor, or selection of the second mode, in which information is coded, which indicates generation of a motion vector predictor on the basis of units or pixels included into a pre-coded area adjacent to the current unit; determination of the motion vector predictor of the current unit in accordance with the selected mode, and coding of information on the motion vector predictor of the current unit; and coding of the vector of difference between the motion vector of the current unit and predictor of the motion vector of the current unit.

EFFECT: increased efficiency of coding and decoding of a motion vector.
