Genlock input and output connectors —
An external blackburst signal
may be connected to the input (In) female BNC connector for genlocking the
video signal in broadcast or other sync-critical applications.
Connect any downstream equipment, which requires genlocking, to the
output (Out) female BNC connector to route the blackburst signal
throughout the system in broadcast or other sync-critical applications.
See Genlock and Vertical Interval Switching in this chapter.
