Abstract
For encoding and decoding images, an image encoding device divides each picture into sub-pictures that can be independently displayed, and signals layout information about the sub-pictures, and an image decoding device identifies each sub-block through the layout information and decodes the sub-pictures. A video decoding apparatus and method are configured to decode a bitstream containing an encoded sequence of pictures which are partitioned into a plurality of subpictures including a plurality of coding tree blocks.
