METHOD AND APPARATUS FOR ENCODING VIDEO, AS WELL AS METHOD AND APPARATUS FOR DECODING VIDEO, SUPPLEMENTED BY ARITHMETIC CODING Russian patent published in 2016 - IPC H04N19/91 H04N19/13 H03M7/40 

Abstract RU 2586321 C2

FIELD: information technology.

SUBSTANCE: invention relates to decoding video based on arithmetic decoding. Disclosed is method of decoding a video through symbol decoding, said method including: parsing symbols of image blocks from a received bit stream; classifying a current symbol into a prefix bit string and a suffix bit string based on a threshold value determined according to a size of a current block; performing arithmetic decoding by using an arithmetic decoding method determined for each of prefix bit string and suffix bit string; and performing inverse binarisation by using a binarisation method determined for each of prefix bit string and suffix bit string.

EFFECT: technical result is improved efficiency of symbol decoding process.
