FIELD: information technology.

SUBSTANCE: invention relates to video decoding. Video predictive decoding method is intended for execution of processes including: the step of decoding, whereat decoded are supplementary information and compressed data of residual signal of the target area of decoding from the compressed data; the step of reconstruction of motion information, whereat the motion vector is restored used for generating a predicted signal of the target area of decoding; the step of saving the motion information, whereat saved is the motion vector; the step of motion compensation, whereat generated is the predicted signal of the target area of decoding basing on the motion vector; the step of reconstruction of the residual signal, whereat reduced is the recovered residual signal of the target area of decoding; and the step of saving the image.

EFFECT: technical result is increased efficiency of suppressing noise in the predicted signal during bidirectional prediction.
