FS1 Installation and Operation Manual — Connectors
Reference Video (looping)
These two BNC connectors allow you to synchronize FS1 outputs to your
house reference video signal (blackburst or composite sync for SD, or Tri-level
for HD). If you have a sync generator or video equipment source to use for
synchronizing other video equipment in your studio, connect its composite
output here. When the FS1 outputs video, it locks to this reference signal.
Reference video does not need to be the same format as the video input/
outputs, but it must have the same vertical rate (for example, 1080i Tri-level
reference video will work for 525 video input and output).
Examples of permissible reference video signals:
•
525 Color Black
•
625 Color Black
•
1080i Tri-level Sync
•
720p Tri-Level Sync
