Disclosed herein are a video encoding/decoding method and apparatus. The video decoding method according to the present disclosure includes: when a current picture is composed of a plurality of tiles and a current tile among the plurality of tiles is partitioned into a plurality of slices, decoding information on the number of slices in tile that indicates the number of the plurality of slices comprised in the current tile; decoding information on a slice height in tile that indicates a height of the plurality of slices comprised in the current tile; and determining the number of the plurality of slices comprised in the current tile and a height of the plurality of slices comprised in the current tile.

Image encoding/decoding method and device

Disclosed are an image encoding method using a skip mode and a device using the method. The image encoding method may comprise the steps of: judging whether there is residual block data of a prediction target block on the basis of predetermined data indicating whether residual block data has been encoded; and, if there is residual block data, restoring the prediction target block on the basis of the residual block data and an intra-screen predictive value of the prediction target block. Consequently, encoding and decoding efficiency can be increased by carrying out the encoding and decoding of screen residual data only for prediction target blocks where there is a need for a residual data block in accordance with screen similarity.

Image encoding method using a skip mode, and a device using the method
