External sync (MAV Plus video models)

The MAV Plus switcher switches between inputs during the vertical interval
period, resulting in glitch-free video switching. The MAV switcher can use an
external signal to synchronize switching during the vertical interval. Without the
external sync locking feature, switching between inputs can result in a brief rolling
(sync loss) or a brief change in the picture size.
