Abstract: An improved wireless split rendering system for displaying Extended Reality (XR) content is discussed. A rendering server and client head-mounted device (HMD) may communicate over a wireless medium, where communication control is given to a server application layer logic. This allows the server to use request pose information from the HMD only when needed for rendering, while preserving bandwidth on the wireless medium for transmitting frames of the rendered content. This reduces contention and improves channel efficiency.

Abstract: Methods, systems, and devices for split rending of multiple graphic layers are described. An extended reality (XR) system may include a processing device that generates and renders multiple graphic layers and a display device that displays the graphic layers to create a virtual environment. The processing device may divide the multiple graphic layer into sets of graphic layers and composite each set into a composite layer for transmission to the display device over a respective stream. Each group of graphic layers may include graphic layers of the same type that are consecutively ordered with respect to their Z orders and that have similar frame rates.
