1. A method for encoding a picture into a bitstream, the method comprising:
encoding a tile partition structure as one or more syntax elements in the bitstream;
determining a number of tiles N in the picture;
encoding a number of slices in the picture, wherein each slice comprises an integer number of tiles;
including in the bitstream a first syntax element representing a width of the current slice in number of tiles;
including in the bitstream a second syntax element representing a height of the current slice in number of tiles;
deriving a top-left position of the current slice as a location of a first tile in raster scan order that is not included in one or more previously derived slices; and
using the width, height, and location to encode the picture.
