FOVEATED OPTIMIZATION OF TV STREAMING AND RENDERING CONTENT ASSISTED BY PERSONAL DEVICES

A mobile device such as a mobile phone is used to image a nearby user for eye tracking at a closer range than would be provided by cameras on a display device such as a TV and send the eye tracking data to a server streaming video being presented on the display. The eye tracking data is used by the server to identify a region of interest (ROI) in the video, which is more highly compressed than regions outside the ROI to facilitate efficient compression of the video game image while preserving the quality of the ROI in the image where the user is looking.
