摘要： A suggested viewport indication is generated and sent for use in a panoramic video. In one example, a method includes receiving encoded video including viewport metadata, decoding the video, extracting the viewport metadata, generating a viewport of the decoded video based on the viewport metadata, and buffering the generated viewport for display.

摘要： Spherical rotation is described for encoding a video that has a wide field of view, such as a spherical or hemispherical video. One example relates to receiving encoded video including rotation orientation metadata, decoding the video, extracting the rotation orientation metadata, rotating the decoded video based on the rotation orientation metadata, generating a view of the rotated decoded video, and buffering the generated view for display.

摘要： Systems, apparatuses and methods may determine, on a per camera basis, an interest level with respect to panoramic video content, identify a subset of cameras in a plurality of cameras for which the interest level is below a threshold, and reduce power consumption in the subset of cameras. Additionally, technology may determine a projection format associated with panoramic video content, identify one or more discontinuous boundaries in the projection format, and modify an encoding scheme associated with the panoramic video content based on the discontinuous boundaries. Moreover, an encoded frame may be assigned to a temporal scalability layer that has a higher priority than a layer to which an asynchronous space warp frame is assigned. Additionally, technology may reduce the encoding complexity of a boundary between an active region and an inactive region in fisheye content.

摘要： Temporal motion vector prediction control is described in video coding. In one example, a method includes receiving a plurality of frames representing encoded video, parsing an uncompressed header for each frame, determining whether a temporal motion vector prediction command is included within the parsed uncompressed header of a first frame, selecting a reference frame from a reference list of frames, retrieving motion vector information from the selected reference frame, performing temporal motion vector prediction on the first frame corresponding to the parsed uncompressed header if a temporal motion vector prediction command is included within the parsed header to form a motion predicted frame, applying a loop filter to the motion predicted frame, and rendering the frame as decoded video.

摘要： Techniques related to video coding are discussed. Such video coding techniques include applying a projective transformation to a reconstructed reference frame based on scene pose difference data indicative of a scene pose change and performing motion compensation using the reprojected reconstructed reference frame as a motion compensation reference frame.

摘要： Rectilinear viewport extraction from a region of a wide field of view is described using messaging in the video transmission field. Some embodiments pertain to a method that includes receiving a wide field of view video, receiving position data from a remote coupled user device, selecting a region of interest in the video based on the received position data, extracting the region of interest from the video, generating region metadata describing the extracted region of interest, encoding the extracted region of interest of the video, and transmitting the encoded video with the region metadata to the user device.

摘要： Systems, apparatuses and methods may provide for technology to improve user experience when viewing simulated 3D objects on a display. Head and upper-body movements may be tracked and recognized as gestures to alter the displayed viewing angle. The technology provides for a very natural way to look around, under, or over objects.
