FIELD: physics, communications.
SUBSTANCE: invention relates to video decoding based on arithmetic decoding. Disclosed is a method of decoding video through decoding symbols, comprising: parsing symbols of image blocks from a received bit stream; classifying the current symbol into a prefix bit string and a suffix bit string based on a threshold value determined according to the size of the current block; performing arithmetic decoding by using an arithmetic decoding method, defined for each of the prefix bit string and the suffix bit string; and performing conversion from binary form by using a method for conversion into binary form, defined for each of the prefix bit string and the suffix bit string.
EFFECT: high efficiency of the symbol decoding process.
