IMAGE DECODING METHOD, IMAGE ENCODING METHOD, IMAGE DECODING DEVICE, IMAGE ENCODING DEVICE AND IMAGE ENCODING AND DECODING DEVICE Russian patent published in 2016 - IPC H04N19/463 H04N19/196 H04N19/176 H04N19/157 H04N19/13

Abstract RU 2602672 C2

FIELD: information technology.

SUBSTANCE: invention relates to techniques of encoding/decoding images. Disclosed is a method of decoding an image using arithmetic decoding. Method comprises determining a context for use in a current block, from among a plurality of contexts, and performing arithmetic decoding on a bit sequence corresponding to current block, using determined context for decoding a binary sequence, wherein bit sequence is obtained by performing arithmetic coding over a control parameter of current block. Further, method comprises performing reverse binarisation of binary sequence for decoding control parameter of current block.

EFFECT: high efficiency of encoding/decoding video data.
