Abstract
Systems and methods are operable to correct synchronization between a video stream and an audio stream presented to a user. An exemplary embodiment receives a synchronization correction instruction, wherein the synchronization correction is configured to be initiated by the user; and incrementally adjusts one of the video stream and the audio stream by a synchronization correction, wherein the synchronization correction advances or retards presentation of at least one of the video stream and the audio stream by a predefined duration.
