Abstract
A video signal decoding method according to the present disclosure includes decoding a first flag representing whether tile index difference value information is present or not, decoding size information for a first slice, decoding tile index difference value information for the first slice when the first flag is true and determining an index of a second tile at a top-left position of a second slice based on the tile index difference value information.
Claims9
A method of decoding a video, the method comprising:
- decoding a first flag representing whether tile index difference value information is present or not;
- decoding size information for a first slice;
- decoding the tile index difference value information for the first slice when the first flag is true;
- determining an index of a second tile at a top-left position of a second slice based on the tile index difference value information,
- wherein the tile index difference value information represents a difference between an index of a first tile at a top-left position of the first slice and the index of the second tile, and
- determining whether to decode size information for the second slice or not based on the index of the second tile in the second slice,
- wherein the size information includes at least one of width information or height information, and
- wherein when the second tile is included in a rightmost tile column in a current picture, decoding of the width information for the second slice is omitted.

A method of encoding a video, the method comprising:
- determining a size of a first slice and a second slice;
- encoding size information for the first slice;
- encoding tile index difference value information for the first slice,
- wherein the tile index difference value information represents a difference between an index of a first tile at a top-left position of the first slice and an index of a second tile at a top-left position of the second slice, and
- determining whether width information for the second slice is to be encoded or not based on the index of the second tile,
- wherein the size information includes at least one of width information or height information, and
- wherein when the second tile is included in a rightmost tile column in a current picture, encoding of the width information for the second slice is omitted.
