    Abstract: Predictive pre-fetching of streams for 360 degree video is described. User view orientation metadata is obtained for a 360 degree video stream that includes data for a plurality of viewports. Data corresponding to one or more high-resolution frames for a particular one of the viewports is pre-fetched based on the user view orientation metadata and those frames are displayed. The high resolution frames are characterized by a higher resolution than for remaining viewports.

    Abstract: A method, including: receiving, by the computer, captured image frames of an interactive environment in which a HMD is disposed; receiving inertial data processed from at least one inertial sensor of the HMD; analyzing the captured image frames and the inertial data to track movement of the HMD, wherein analyzing the captured image frames includes examining changes within a sequence of said captured image frames to track the movement of the HMD, wherein analyzing the captured image frames includes processing the captured image frames to identify and map one or more fixed objects in the interactive environment and tracking the one or more fixed objects to enable the tracking of the movement of the HMD; using the tracked movement of the HMD to adjust a beamforming direction of an RF transceiver towards the HMD; adjusting an angular spread of the RF transceiver based on the movement of the HMD.
