Abstract
Encoding an extended-reality (XR) video frame may include obtaining an XR video frame comprising a background image and a virtual object; obtaining, from an image renderer, a first region of the background image over which the virtual object is overlaid; dividing the XR video frame into a virtual region and a real region, wherein the virtual region comprises the first region of the background image and the virtual object and the real region comprises a second region of the background image; determining, for the virtual region, a corresponding first quantization parameter based on an initial quantization parameter associated with virtual regions; determining, for the real region, a corresponding second quantization parameter based on an initial quantization parameter associated with real regions; and encoding the virtual region based on the corresponding first quantization parameter and the real region based on the corresponding second quantization parameter.
