VIDEO DECODING METHOD USING ARITHMETIC CODING WITH A TWO-DIMENSIONAL SIGNALING OF THE LAST SIGNIFICANT COEFFICIENT

摘要

A method of decoding a video through symbol decoding, the method including parsing symbols of image blocks from a received bitstream; 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 the prefix bit string and the suffix bit string; and performing inverse binarization by using a binarization method determined for each of the prefix bit string and the suffix bit string.
