Abstract
A mixed reality system including a head-mounted display (HMD) and a base station. Information collected by HMD sensors may be transmitted to the base via a wired or wireless connection. On the base, a rendering engine renders frames including virtual content based in part on the sensor information, and an encoder compresses the frames according to an encoding protocol before sending the frames to the HMD over the connection. Instead of using a previous frame to estimate motion vectors in the encoder, motion vectors from the HMD and the rendering engine are input to the encoder and used in compressing the frame. The motion vectors may be embedded in the data stream along with the encoded frame data and transmitted to the HMD over the connection. If a frame is not received at the HMD, the HMD may synthesize a frame from a previous frame using the motion vectors.
