Abstract: Provided are a method and apparatus for determining a context model for entropy encoding and decoding of a transformation coefficient. According to the method and apparatus, a context set index ctxset is obtained based on color component information of a transformation unit, a location of a current subset, and whether there is a significant transformation coefficient having a value greater than a first critical value in a previous subset, and a context offset c1 is obtained based on a length of a previous transformation coefficient having consecutive 1s. Also, a context index ctxids for entropy encoding and decoding of a first critical value flag is determined based on the obtained context set index and the context offset.

Abstract: A method of decoding a motion vector includes: obtaining information indicating a motion vector resolution (MVR) of a current block from a bitstream, selecting one candidate block from among at least one candidate block, based on the MVR of the current block; and obtaining a motion vector of the current block corresponding to the MVR, by using a motion vector of the determined one candidate block as a prediction motion vector of the current block.
