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; 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, and
wherein parsing height information for slices starting from an n-th slice to a last slice within the tile is skipped and heights of slices starting from the n-th slice to at least a directly previous slice of the last slice within the tile are derived to be the same as each other.
