Claim 11:
12. The method of claim 9,
wherein when each subpicture of the video picture includes only one slice and the height of the subpicture is greater than or equal to one tile row, for each slice with a picture-level slice index i of the video picture, a value of CtbAddrInSlice[i][j] specifying a picture raster scan CTB address of a j-th CTB within a slice is derived from the picture raster scan CTB address of the j-th CTB in an order of CTBs in the subpicture,
wherein i is in a range of 0 to a number of slices in the video picture minus 1, inclusive and j is in a range of 0 to a number of coding tree units (CTUs) in the slice minus 1, inclusive,
wherein the order of the CTBs in the subpicture is such that a first CTB in a first tile with a first tile index is placed before a second CTB in a second tile with a second tile index,
wherein a value of the first tile index is less than a value of the second tile index, and
wherein an order of the CTBs within one tile in the subpicture is ordered in a raster scan of the CTUs in the one tile.
