1. A video decoding method, comprising:
acquiring a bitstream including a syntax element;
performing at least one of a context model determination, a probability update, and a probability interval determination based on the syntax element; and
arithmetically decoding the syntax element based on the context model determination,
wherein the context model determination comprises selecting a probability model for the syntax element,
wherein the probability model for the syntax element of a current block is determined based on a prediction mode of an adjacent block of the current block, and
wherein the probability model for the syntax element of the current block is determined based on whether the prediction mode of the adjacent block is a matrix weighted intra prediction mode.
