Extron electronic MSG0804 manual Vertical Interval Switching, Connecting the external sync signal

Vertical Interval Switching

When the switching between inputs, the resulting image change should be seamless and clean. Vertical interval switching makes this seamless image change possible. MSG switchers are able to provide vertical interval switching by using an external sync (genlock) signal to synchronize switching during the vertical sync interval. Without external sync locking, switching between inputs can result in a brief rolling (sync loss) or a brief change in the picture size. If no external sync timing source is connected to the switcher, switching occurs immediately.

Connecting the external sync signal

The Genlock In connector of the MSG switcher receives the external sync timing signal. The Genlock Out connector allows the signal to be passed on to another video device, if required.

To enable vertical interval switching, connect an external sync signal (from an Extron BBG6A Blackburst Generator or other source) to the Genlock In BNC connector ( 3 ) for genlocking the video signal in broadcast or other sync-critical applications. Connect any downstream equipment that requires genlocking to the Genlock Out BNC connector to route the external sync signal through the switcher.
