Abstract
The present invention relates to a video encoding method, to a video decoding method, and to an apparatus using same. The video encoding method according to the present invention comprises the steps of: setting a tile and a slice for the inputted current picture; performing encoding based on the tile and the slice; and a step of transmitting the encoded video information. The current picture may include one or more tiles and one or more slices. The largest coding units (hereinafter, referred to as LCUs) in the slice may be arranged based on a tile scan.

A method for decoding video, by a decoding apparatus, the method comprising:
- receiving video information including information on a tile and information on a slice, wherein the tile is a rectangular region including one or more coding tree units (CTUs) within a particular column and a particular row and the slice comprises an integer number of CTUs;
- deriving the tile and the slice in a current picture based on the received video information, wherein the current picture includes one or more tiles and one or more slices;
- and
- performing decoding for the current picture based on the one or more tiles and the one or more slices,
- wherein plural coding units are divided from an CTU,
- wherein CTUs in the tile are ordered consecutively in raster scan order,
- wherein tiles in the slice are ordered consecutively in raster scan order when the slice covers an integer number of the tiles, and
- wherein tile IDs specifying the tiles ordered in the slice are consecutive.
A decoding apparatus for decoding video, the apparatus comprising:
- an decoder for receiving video information including information on a tile and information on a slice, wherein the tile is a rectangular region including one or more coding tree units (CTUs) within a particular column and a particular row and the slice comprises an integer number of CTUs, for deriving the tile and the slice in a current picture based on the received video information, wherein the current picture includes one or more tiles and one or more slices, and for performing decoding for the current picture based on the one or more tiles and the one or more slices;
- and
- a memory for storing the decoded current picture,
- wherein plural coding units are divided from an CTU,
- wherein CTUs in the tile are ordered consecutively in raster scan order,
- wherein tiles in the slice are ordered consecutively in raster scan order when the slice covers an integer number of the tiles, and
- wherein tile IDs specifying the tiles ordered in the slice are consecutive.
