Claim:
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 coding tree units and information on a slice which is a sequence of coding tree units; specifying the tile and the slice in a current picture based on the received video information; and performing a decoding operation based on the tile and the slice to generate reconstructed samples in the current picture, wherein a coding tree unit can be split into coding units with quad-tree structure and a coding unit can be partitioned into prediction units, wherein a deblocking filtering is applied to the reconstructed picture, wherein the current picture is partitioned into one or more tiles and one or more slices, wherein each slice and tile in the current picture is configured based on at least one of a first constraint and a second constraint, wherein the first constraint, each tile in the slice does not traverse a boundary of the slice, and wherein the second constraint, each slice in the tile does not traverse a boundary of the tile.
