1. A video decoding method performed by a decoding apparatus, the method comprising:
obtaining video information including information on a tile and information on a slice from a bitstream;
deriving a tile and a slice in a current picture based on the video information; and
performing a decoding for the current picture based on the derived tile and the derived slice,
wherein the current picture is partitioned into one or more tiles and one or more slices,
wherein a coding tree unit is divided into coding units based on a quad tree structure,
wherein each slice in the current picture fulfills at least one of the specific restrictions for a tile, the specific restrictions are that 1) each slice contains an integer number of complete tiles, 2) all coding tree units included in each slice belong to the same tile,
wherein based on one slice including an integer number of complete tiles, the one slice includes a plurality of tiles, and a vertical boundary of the one slice always overlaps a vertical boundary of the plurality of tiles, and
wherein based on all coding tree units included in the one slice belonging to the same tile, one tile includes a plurality of slices, and a vertical boundary of the one tile always overlaps a vertical boundary of the plurality of slices.
