1. A video decoding method comprising:
determining whether a picture is encoded according to a plurality of sub-pictures;
partitioning the picture into the plurality of sub-pictures when it is determined that the picture is encoded according to the plurality of sub-pictures; and
determining whether the plurality of sub-pictures have independence,
wherein the determination on whether to have independence is based on a first flag representing whether all of the plurality of sub-pictures have independence,
wherein a first value for the first flag indicates that all of the plurality of sub-pictures have independence, and
wherein a second value for the first flag indicates that at least one of the plurality of sub-pictures does not have independence.
