Abstract: A video decoding apparatus decodes a sequence of one or more pictures in the unit of blocks which are split from each picture. The apparatus comprising a decoder configured to reconstruct, from a bitstream, a current motion vector difference of the current block among the blocks which belong to the sequence of one or more pictures, and an image decoder configured to predict and decode the current block using the motion vector of the current block. When the current motion vector difference of the current block is zero, the resolution of the current motion vector difference of the current block is set to the ¼ pixel precision without the information on the motion vector resolution extracted.

Abstract: Disclosed herein is a method for decoding a video including determining a coding unit to be decoded by block partitioning, decoding prediction syntaxes for the coding unit, the prediction syntaxes including a skip flag indicating whether the coding unit is encoded in a skip mode, after the decoding of the prediction syntaxes, decoding transform syntaxes including a transformation/quantization skip flag and a coding unit cbf, wherein the transformation/quantization skip flag indicates whether inverse transformation, inverse quantization, and at least part of in-loop filterings are skipped, and the coding unit cbf indicates whether all coefficients in a luma block and two chroma blocks constituting the coding unit are zero, and reconstructing the coding unit based on the prediction syntaxes and the transform syntaxes.
