METHOD FOR SCALABLE ENCODING AND METHOD FOR SCALABLE DECODING OF VIDEO INFORMATION, APPARATUS FOR SAID METHODS, PROGRAM FOR SAID METHODS AND RECORDING MEDIUM WHERE SAID PROGRAM IS STORED Russian patent published in 2012 - IPC H04N7/32 

FIELD: information technology.

SUBSTANCE: disclosed is a method for scalable encoding of video information, which calculates a weighting coefficient and indicates change in brightness between the encoded target region of the image and the region of a reference image in an overlying layer, calculates a motion vector, and generates a prediction signal by applying the weighting coefficient to the decoded signal of the region of the reference image indicated by the motion vector, and compensating for movement. If the immediate underlying region of the image has performed interframe prediction in the immediate underlying layer, the method identifies the region of the reference image of the immediate underlying layer which was used by the immediate underlying region of the image as a prediction reference for predicting movement, and calculates a weighting coefficient by applying the weighting coefficient which was used by the immediate underlying region of the image in weighted prediction of movement, to the DC component of the region of the image in the overlying layer, and accepting the result of application as the DC component of the immediate underlying region of the image.

EFFECT: high efficiency of scalable encoding.
