Abstract:
1. A video decoding method based on tiles and slices in a current picture by decoding apparatus, the method comprising: receiving video information including information on a tile which is a rectangular region comprising largest coding units and information on a slice which is a sequence of largest coding units; specifying a tile and a slice in a current picture on the basis of the received video information; and performing a decoding operation on the basis of the specified tile and the specified slice to reconstruct samples in the current picture, wherein a largest coding unit can be split into coding unit with quad-tree structure and the coding unit can be partitioned into prediction unit, wherein whether inter prediction is applied or intra prediction is applied is determined per each coding unit and mode of inter prediction and intra prediction is determined per each prediction unit, wherein the current picture is partitioned into one or more tiles and one or more slices, wherein each tile is decoded independently in other tiles and each slice is decoded independently in other slices, and wherein the tile is not configured to be across a boundary of the slice when the slice includes the tile and the slice is not configured to be across a boundary of the tile when the tile includes the slice.
