Abstract (en)

[origin: WO2021047590A1] A method for signaling subpicture structures for coded video is provided. A video decoder receives data from a bitstream to be decoded as a sequence of video pictures. The video decoder receives from the bitstream subpicture specification for one or more subpictures in the sequence of video pictures. The subpicture specification identifies a position and a size for each subpicture by providing an index that identifies a coding tree unit (CTU) for the subpicture. The video decoder reconstructs each subpicture for the sequence of video pictures according to the subpicture specification.
