Signaling of multiview tiled volumetric video

A method comprising:

• receiving and decoding a bitstream for a compressed video;
• identifying a mapping of view numbers of a plurality of images and a plurality of subpicture identifiers, each of the plurality of subpicture identifiers associated with a defined location in a video frame, wherein the mapping is signaled in the bitstream, and wherein each one of the view numbers is assigned to one image of the plurality of images based on a corresponding one of a plurality of camera viewpoints of a scene;
• and
• instructing a display of at least one image based on at least one of the plurality of images.

An apparatus comprising:

• a communication interface;
• and
• a processor operably coupled to the communication interface, the processor configured to:
• obtain a plurality of images each corresponding to one of a plurality of camera viewpoints of a scene;
• assign a view number to each image of the plurality of images based on the corresponding one of the plurality of camera viewpoints of the scene;
• map the view number of each image of the plurality of images to one of a plurality of subpicture identifiers each associated with a defined location in a video frame;
• combine the plurality of images into the video frame according to the subpicture identifiers;
• and
• compress and transmit the video frame as part of a bitstream, wherein the mapping of the view numbers and the plurality of subpicture identifiers is signaled in the bitstream.
