Setting Up Genlock and Vertical Interval Switching
A genlock (black burst generator) device can be connected to the scan converter to
synchronize it with other system components for seamless vertical interval
switching between sources.
Vertical interval switching setup
For vertical interval switching (to allow clean switching between signals from
several devices during the vertical blanking period of each signal), a composite
sync signal can be applied at the Genlock In connector, and also passed to another
device via the Genlock Out connector.
