Claim 16:
17. A non-transitory computer-readable storage medium storing instructions that cause a processor to:
determine, for a conversion between a video comprising a video picture referring to a picture parameter set and a bitstream of the video, a scanning process is applied to the video picture, wherein the video picture is partitioned into one or more tiles, one or more slices, and a plurality of coding tree units;
determine, in the scanning process, that the picture parameter set includes a list of syntax elements indicating tile column widths for N tile columns having N indexes, respectively, wherein N is an integer; and
perform the conversion based on the determining,
wherein the list of syntax elements comprises a first syntax element, a value of which plus 1 specifies directly a width of a N-th tile column of the N tile columns in units of coding tree blocks without referring to other information,
wherein the value of the first syntax element is used to derive a width of a tile column with an index greater than the N indexes,
wherein a number of explicitly provided slice heights for slices in a video tile comprising a rectangular slice in the video picture is equal to M, and M is an integer no less than 0, and
wherein when a difference between a height of the video tile in units of coding tree blocks and a sum of slice heights of the M slices is less than a uniform slice height, a slice height of a (M+1)-th slice of the video tile is set to be the difference.
