1. A method comprising:
determining that a current picture has been partitioned into a plurality of tiles, the tiles being grouped in a plurality of slices;
decoding slice determination method information from a bitstream;
determining, based on the slice determination method information, that the plurality of slices in the current picture are defined based on a rectangular shape mode; and
determining, based on whether a first slice is a sequentially last slice among the plurality of slices in the current picture, whether to decode tile index differential information for the first slice from the bitstream, the tile index differential information representing a difference between an index of a tile at a predetermined position in the first slice and an index of a tile at the predetermined position in a second slice.
