Abstract
A network processing system obtains a viewport of a client device for volumetric video and a two-dimensional (2D) subframe of a frame of volumetric video is obtained associated with the viewport. Viewports may be obtained from the client device or be predicted. 2D subframes and reduced resolution versions of frames can be transmitted to the client device. A client device may request volumetric video from the network processing system and provides a viewport to the network processing system. The client device may obtain from the network processing system reduced resolution versions of volumetric video frames and 2D subframes in accordance with the viewport. The client device may determine whether a current viewport matches the viewport associated with the obtained 2D subframe and provides a display based on either that subframe (upon a match) or a 2D perspective of the reduced resolution frame associated with the current viewport (if no match).
