1. A non-transitory storage medium storing an encoded bitstream for video signals, the encoded bitstream comprising:
a picture partitioned into a plurality of tiles, wherein a number of the tiles are included into a tile group; and
a plurality of syntax elements, wherein the plurality of syntax elements comprises a flag in a parameter set, wherein the flag indicates that the tile group is a raster scan tile group when the flag is set to a first value and the tile group is a rectangular tile group when the flag is set to a second value, wherein the raster scan tile group contains tiles consecutive in raster scan order of the picture, and the rectangular tile group contains tiles collectively forming a rectangular region of the picture.
