External syync connections (wideband and video BMEs only)

For NTSC, PAL, or 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.

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

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 2-16 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.
