Claim 7:
8. A method implemented by an encoder, the method comprising:
partitioning a picture into a plurality of slices;
partitioning each of the plurality of slices into a plurality of tiles, 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;
determining a top left tile index associated with a first slice;
encoding the top left tile index in a bitstream to indicate a position of the first slice and a boundary of the first slice when the first slice is a rectangular slice, wherein the position of the first slice is determined by assigning the addresses of all the CTUs in the first slice based on the top left tile index;
encoding 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, and wherein the slice type is set to two when the slices are intra-prediction (I) slices; and
encoding the first slice in the bitstream to encode the picture.
