Abstract:
The present disclosure relates to a method and apparatus for improving the encoding efficiency by adaptively changing the resolution of the motion vector in the inter prediction encoding and inter prediction decoding of a video. The apparatus includes: a predicted motion vector calculator for calculating a predicted motion vector of a current block to be encoded using motion vectors of one or more surrounding blocks; and a skip mode encoder for encoding a result of performing a prediction of the current block and information indicating that the current block is a skip block when the predicted motion vector satisfies a skip condition, wherein at least one motion vector among the motion vectors of the surrounding blocks and the motion vector of the current block has a resolution different from resolutions of the other motion vectors.

Claim (Index 1):
A video decoding apparatus for decoding a motion vector of a current block to be decoded, the apparatus comprising:\n a decoder configured to decode, from a bitstream, motion vector resolution identification information to be applied to the current block or an image area in which the current block is located, the motion vector resolution identification information indicating one of a plurality of motion vector resolutions; and an inter predictor configured to\n derive a predicted motion vector of the current block from one or more neighboring blocks of the current block, \n convert the predicted motion vector based on a motion vector resolution indicated by the motion vector resolution identification information, and \n reconstruct the motion vector of the current block having the motion vector resolution indicated by the motion vector resolution identification information, by using the converted predicted motion vector.
