Abstract
Systems, methods, and instrumentalities are disclosed relating to region of interest (ROI) video coding using tiles and tile groups. An encoded video sequence including a plurality of tiles may be received. The plurality of tiles may be divided into one or more tile groups. Signaling indicating parameters of the one or more tile groups may be received. A tile group of the one or more tiles groups may be decoded and a picture relating to the decoded tile group may be displayed. The decoded tile group may overlap the ROI. The ROI may correspond to the displayed picture and the displayed picture may be a portion of the encoded video sequence. The tile groups that do not overlap the ROI may not be decoded.
