Abstract: In one example, a device for retrieving video data includes a display interface coupled to a display, a memory configured to store video data, and one or more processors configured to determine a plurality of regions of video data to be displayed via the display, retrieve video data having a first quality for a first subset of the plurality of regions at which a visual focus of a user is directed, retrieve video data having a second quality for a second subset of the plurality of regions that neighbor the first subset of the plurality of regions, wherein the second quality is lower than the first quality, and retrieve video data having a third quality for a third subset of the plurality of regions that is outside the first subset and the second subset, wherein the third quality is lower than the second quality.
