Claim 14:
15. A video coding device comprising:
a receiver configured to receive a bitstream including picture data coded in a plurality of slices and a slice header containing a slice type, wherein the slice type is set to zero when the slices are bidirectional inter-prediction (B) slices, wherein the slice type is set to one when the slices are unidirectional inter-prediction (P) slices, wherein the slice type is set to two when the slices are intra-prediction (I) slices, wherein each of the slices contains a plurality of tiles, and wherein each of the tiles contains one or more coding tree units (CTUs) containing coded picture data, and wherein addresses of the CTUs are assigned based on tile indices of corresponding tiles; and
a processor configured to:
determine a top left tile index associated with a first slice;
determine a position of the first slice and a boundary of the first slice based on the top left tile index when the first slice is a rectangular slice, wherein determining the position of the first slice includes determining the addresses of all the CTUs in the first slice based on the top left tile index; and
decode the first slice to generate a reconstructed picture based on the boundary of the first slice and the slice type.
