1. A method for video decoding in a decoder, the method comprising:
receiving a video bitstream comprising a first sub-picture and a second sub-picture, the first sub-picture and the second sub-picture both being of a picture; and
decoding the first sub-picture of the picture, independently from the second sub-picture, using sub-picture, tile group, and tile partitioning, wherein
(i) the first sub-picture is a first rectangular region of the picture and the second sub-picture is a second rectangular region of the picture, the second rectangular region being different from the first rectangular region,
(ii) the first sub-picture includes a first plurality of tiles, and the second sub-picture includes at least one tile,
(iii) the first sub-picture and the second sub-picture do not share a common tile,
(iv) the first plurality of tiles of the first sub-picture are grouped into at least two first tile groups, and
(v) the first sub-picture is decoded in accordance with a decoding technology wherein loop filtering control at a boundary between the at least two first tile groups is only allowed where each of the at least two first tile groups is rectangular.
