Abstract: In various examples there is a method performed by a Head Mounted Display, HMD, comprising a high field rate display configured to display fields of rendered frames at a field rate. The method comprises receiving a stream of the rendered frames for display on the high field rate display, the stream of rendered frames having a frame rate. The process applies an early stage reprojection to the rendered frames of the stream of rendered frames at a rate which is lower than the field rate. The process applies a late stage reprojection to fields of the rendered frames at the field rate, wherein the early stage reprojection uses more computational resources than the late reprojection.

Abstract: A display pose of a client computing device is computed in a hybrid manner using both the client computing device and a server. Using the client computing device, an initial pose of the client computing device at an initial time is computed. A prospective pose at a target time is predicted using the client computing device. The prospective pose is sent along with auxiliary data from the client computing device to the server and a display pose of the client computing device at a display time is computed. The display pose is computed using the prospective pose and the auxiliary data.

Abstract: Techniques for improving remote rendering and reprojection are disclosed herein. A color image is generated, where this color image includes overlapping content regions. A depth buffer is generated for the color image and includes depth values for the pixels in the color image. The depth buffer includes both essential and non-essential depth discontinuities. While preserving the essential depth discontinuities, the non-essential depth discontinuities are eliminated from the depth buffer. New non-essential discontinuities are prevented from being included in the final version of the depth buffer. The color image is encoded into a color image video stream, and the modified depth buffer is encoded into a depth buffer stream. The color image video stream and the depth buffer stream are then transmitted to a remotely located HMD. The HMD then reprojects the color image based on the depth values in the depth buffer.
