External sync connection
When switching between inputs, the resulting image change
should be seamless, or clean. The MAV switchers 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.
External Sync In connector — Connect an external sync signal

to this BNC connection for genlocking the video signal in
broadcast or other sync-critical applications.
External Sync Out connector — Connect any downstream
equipment that requires genlocking to this BNC connector to
route the external sync signal throughout the system in
broadcast or other sync-critical applications.
Figure 2-7 shows a basic external sync configuration. The Ext
Sync In connector receives a timing signal. The Ext Sync Out
connector allows the signal to be passed on to another video
device, if required.
Figure 2-8 shows a typical configuration in which the timing
source passes through three video cameras and a video scan
converter before connecting to the switcher. This type of video
camera is capable of synchronizing with the external timing
source for video editing applications.
If no external sync timing source is connected to the switcher,
switching occurs immediately.
