Lip Sync

Because consumer electronics devices are using increasingly complex digital signal processing to enhance the clarity and detail of the content, synchronization of video and audio in user devices has become a greater challenge and could potentially require complex end-user adjustments.

One of the new features enabled in HDMI 1.3, Lip Sync functionality enables the automatic synchronization of video and audio signals, correcting for processor lags that can force audio and video timing out of proper alignment.

HDMI 1.3 incorporates this automatic synchronization of audio and video signals between the display and speaker outputs with total accuracy.
