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 an 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 immersive video asset such that the viewport comprises a higher video quality than the remaining portions when displayed by the client device.
