Abstract
A video decoding apparatus for predicting a current block to be decoded, includes: a bitstream decoder to extract an index for use in identifying a predicted motion vector of the current block and a differential motion vector from a bitstream; and a predictor to generate a predicted block of the current block based on the predicted motion vector and the extracted differential motion vector, wherein the predicted motion vector of the current block is determined to be a motion vector identified by the extracted index in a motion estimation mode of an inter prediction mode, and wherein the extracted index corresponds to one or more representative blocks determined using neighboring blocks of the current block, in consideration of priorities of block positions.
