Abstract: A system and method for providing immersive video based on gaze vector information. A gaze vector is obtained from a client device operating to display a 360° immersive video asset to a user, wherein each video frame comprises an array of tiles projected on a 3-dimensional (3D) display environment viewed by the user in which the user is immersed, the gaze vector defining a gaze direction in the 3D display environment where the user is viewing (i.e., a viewport) at any particular time. Angular separations between the viewport and remaining portions of the video frame are used in selecting different video qualities of the 360° immersive video asset such that the viewport comprises a higher video quality than the remaining portions when displayed by the client device.

Abstract: A system and method for optimizing defragmentation of content in a content delivery network (CDN). In an example, a manifest available to the content delivery node with respect to a particular content as well as segment files stored in a database cache of the content delivery node are analyzed to determine if any segment files referenced by the manifest are absent from the database cache. If so, one or more delivery rules associated with the content delivery node based on historical ABR asset delivery patterns may be applied to determine representations of the absent segment files that satisfy the one or more delivery rules. After determining compliant representations of the absent segment files, they may be pulled from another content delivery node of the CDN (e.g., a parent node or an edge server node).
