Abstract
Devices and methods are disclosed for detecting a focus of at least one viewer as being directed to a particular region of a video display. A first portion of a frame of video for presentation in the region of the viewer's focus is processed differently than another portion of the frame of video related to a region that is not part of the viewer's focus.
