Claim 0:
1. A method of decoding a video, the method comprising:
partitioning a current picture into a plurality of tiles grouped according to a plurality of rectangular slices;
decoding slice partitioning information from a bitstream, the slice partitioning information specifying a slice definition method;
determining that the slice definition method is a rectangular slice definition method;
in response to determining that the slice definition method is the rectangular slice definition method, decoding tile index delta information for one or more first rectangular slices of the plurality of rectangular slices,
wherein, for each of the one or more first rectangular slices, the tile index delta information specifies a difference between an index of a tile located a top left of that first rectangular slice and an index of a tile located at a top left of a respective other rectangular slice of the plurality of rectangular slices, and
wherein decoding the tile index delta information is omitted for a sequentially last one among the plurality of rectangular slices in the current picture.
