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.
