FIELD: physics, computer engineering.
SUBSTANCE: invention relates to computer engineering and specifically to encoding and decoding a motion vector by predicting the motion vector of a current unit. The method of encoding a motion vector includes a step for selection from a first mode and a second mode. Information indicating a motion vector predictor from at least one motion vector predictor is encoded in the first mode. Information indicating generation of the motion vector predictor based on pixels included in a pre-encoded region adjacent to the current unit is encoded in the second mode. The method also involves determining the motion vector predictor of the current unit in accordance with the selected mode and encoding information on the motion vector predictor of the current unit.
EFFECT: high accuracy of predicting and encoding a motion vector.
