Abstract
A method is configured to process a bitstream generated by encoding a sequence of pictures partitioned into a plurality of subpictures. The method includes steps of: decoding, from the bitstream, partitioning information indicating a partitioning structure in which the pictures belonging to the sequence are partitioned into the subpictures; decoding ID information for the subpictures and mapping an ID to each of the subpictures by using the ID information; and reconstructing blocks within at least one subpicture by using the mapped ID.
