CODING DEVICE AND METHOD, DECODING DEVICE AND METHOD Russian patent published in 2018 - IPC H04N19/503 H04N19/30 H04N19/70 

FIELD: physics.

SUBSTANCE: method is carried out through the use of the installation, using a scheme, of information for generating a reference image that is used to generate information of the first reference image using information of the first reference image setting the first reference slice image that is used when the first scaled image is encoded to the image having a hierarchical structure, and information of the second reference image setting the second reference slice image of the second scaled image, which is available together with the first scaled image; encoding, using a scheme, the first scaled image by using the first reference image; generating, using a scheme, the encoded data; and transmitting, using a scheme, the encoded data and information of generating the reference image.

EFFECT: increasing the coding efficiency.
