When you're watching a DVD or other digital video sources, you may occasionally notice the audio doesn't match the video and the sound is delayed. For instance, you may see a person's lips move and not immediately hear dialogue. That's because processing a video image can, at times, take longer than processing the audio signal. This is called latency, and the AV sync feature is designed to correct for it.
