Abstract
A method decodes video data based on gaze sensing. The method may decode an encoded video stream received from an encoder associated with a camera, and present the decoded video stream on a display of a device. The method may further detect a gaze point of an operator viewing the display, designate locations associated with the decoded video stream, based upon the gaze point, as skip block insertion points. The method may send the locations to the encoder, wherein the encoder reduces an update rate of inter-frame coded blocks corresponding to the skip block insertion points when encoding video data produced by the camera. An apparatus can implement the method to decode video data based on gaze sensing.
