Abstract
Systems and methods are operable to synchronize presentation between video streams and separately received audio streams. An exemplary embodiment receives a first media content stream at a media device, wherein the first media content stream comprises at least a video stream portion; receives a second media content stream at the media device, wherein the second media content stream comprises at least an audio stream portion; delays the audio stream portion of the second media content stream by a duration corresponding to at least one synchronization time delay; communicates the video stream portion of the first media content stream to a visual display device; and communicates the delayed audio stream portion of the second media content stream to an audio presentation device, wherein a visual scene of the video stream portion of the first media content stream is substantially synchronized with sounds of the audio stream portion of the second media content stream.
