External sync connections (wideband and video BMEs only)
For NTSC/PAL/SECAM video, when the switcher switches between inputs, the
resulting change in image should be seamless, or clean. The Matrix 12800 switcher
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.

Figure 2-14 shows a basic external sync configuration. The Ext Sync In connector
receives a timing signal. The Out connector allows the signal to be passed on to
another video device, if required.

External sync only works for inputs that have been virtualized as NTSC/PAL/
SECAM video only, not for inputs virtualized as RGB video.
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.
