The 8916 delays digital audio to adjust for
lip sync errors. Lip sync specifications are
usually expressed as +1/-2 video frames of
audio leading/lagging video. Because human
perception tolerates audio lagging better than
audio leading video, the specification is looser
for audio lag. The 8916 offers tremendous
flexibility with two forms of delay that are
summed—a fixed delay of up to 0.5 seconds
and a variable delay based on the signal input
from one of our video frame synchronizers.
Key applications include adjusting for a large
fixed lip sync error while continuously adjusting
audio delay to match video delay created from
a video frame sync.
