Operation

The 628’s sensing circuit moni­tors the loss of scrambled video.
The absence of the scrambled
video causes the 628 to auto­matically switch to the primary
input. It will remain in this state
until the scrambled video returns
to the sense input causing the
628 to switch back to the sec­ondary input.
