Abstract RU 2639662 C1

FIELD: physics.

SUBSTANCE: image prediction decoding method, in which the encoded identification information data is extracted from the compressed data, which sets the area that is used to generate the prediction signal of the target area, and the encoded residual signal data; generating a prediction signal for establishing an adjacent area from a plurality of neighbouring areas adjacent to the target area based on the identification information for generating a prediction signal of the target area from the recovered signal using (i) mode information that defines an inter-picture prediction method, (ii) numbers of a reference picture, and (iii) a motion vector; restoring the residual reconstruction signal of the target area; generating and storing the reconstruction signal of the target area based on the prediction signal of the target area and the residual reconstruction signal.

EFFECT: reducing the prediction errors of the target block.
