Classification: CPC H | IPC H

Claim 0:
1. A video decoding method performed by a video decoding apparatus, the method comprising:
parsing number information related to a number of slices each having its height explicitly signaled within a tile of a current picture from a bitstream;
parsing height information related to heights of slices each having its height explicitly signaled from the bitstream based on the number information;
deriving a number of slices within the tile based on the number information and the height information; and
decoding the current picture based on the slices within the tile,
wherein, based on the number of the slices each having its height explicitly signaled being equal to n, heights of a 0-th slice to an (n−1)-th slice within the tile are derived based on the height information,
wherein a height of an n-th slice to a height of a directly previous slice of a last slice within the tile are derived based on the height of the (n−1)-th slice,
wherein a height of the last slice within the tile is derived based on a remaining height after subtracting the heights of other slices within the tile from a height of the tile, and
wherein the number information and the height information are included in a picture parameter set.
