Image encoding/decoding method and device

摘要

A video decoding method performed by a video decoding apparatus includes: determining a current block to be decoded, by decoding block size information from a bitstream; decoding a skip information of the current block from the bitstream, the skip information indicating whether the current block is a skip block; when the skip information indicates that the current block is the skip block, decoding a skip motion information of the current block from the bitstream, and reconstructing the current block directly from a predicted block predicted based on the skip motion information, without reconstructing a residual signal information from the bitstream; and when the skip information indicates that the current block is not the skip block, decoding an intra or inter prediction information of the current block and a residual signal information from the bitstream, and reconstructing the current block based on the prediction information and the residual signal information.

1. A video decoding method, comprising:
determining a current block to be decoded, by decoding block size information from a bitstream; decoding a skip information of the current block from the bitstream, the skip information indicating whether the current block is a skip block; when the skip information indicates that the current block is the skip block, decoding a skip motion information of the current block from the bitstream, and reconstructing the current block directly from a predicted block predicted based on the skip motion information, without reconstructing a residual signal information from the bitstream; and when the skip information indicates that the current block is not the skip block, decoding an intra or inter prediction information of the current block and a residual signal information from the bitstream, and reconstructing the current block based on the prediction information and the residual signal information, wherein the determination of the current block to be decoded comprises: decoding a bitstream to reconstruct a first information on a minimum block size and a second information on a difference between a maximum block size and the minimum block size, determining the maximum block size based on the first and second information, reconstructing a partition flag indicating whether each node, starting from a node of an uppermost layer having the maximum block size in a tree structure, is partitioned into four nodes of a lower layer, and identifying, as the current block to be decoded, a block corresponding to a node which is not further partitioned.
