Multiple path audio video synchronization
First Claim
1. A method comprises:
- receiving an audio-video signal via a first communication path;
capturing a representation of an audio component of the audio-video signal, wherein the audio component was rendered audible via a second communication path;
deriving a reference representation of the audio component of the audio-video signal received via the first communication path; and
aligning a video component of the audio video-signal of the first communication path with the audio component of the audio video signal of the second communication path based on the representation of the audio component and the reference representation of the audio component.

Abstract
Audio video synchronization begins by receiving an audio-video signal via a first communication path. The processing continues by capturing a representation of an audio component of the audio-video signal, wherein the audio component was rendered audible via a second communication path. The processing continues by deriving a reference representation of the audio component of the audio-video signal received via the first communication path. The processing continues by aligning a video component of the audio video-signal of the first communication path with the audio component of the audio video signal of the second communication path based on the representation of the audio component and the reference representation of the audio component.

11. A system comprises:
-
a source for providing an audio-video signal via a first communication path and an audio component of the audio-video signal via a second communication path; and
a remote device for capturing a representation of the audio component of the audio-video signal from the second communication path, wherein at least one of the source and the remote device aligns a video component of the audio video-signal provided via the first communication path with the audio component of the audio video signal provided via the second communication path based on a reference representation of the audio component of the audio-video signal provided via the first communication path and the representation of the audio component. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
