First, reference: "LiveBook: How do I physically connect components of a GFX system?

To make input/output connections for downstream (switcher) keying with Program access:

  1. Connect Program channel output from the switcher to Input 1.
  2. Connect Output 1 as Fill to the switcher.
  3. Connect Output 2 as Key to the switcher.
  4. Connect the top right Reference In connection to a reference signal (black burst or tri-level) generator.

In addition to these physical connections, connections must be configured via the SportApp software. 

See illustration below:

Note that the switcher return path is optional, and it can also come from the IO box itself
  • SDI Input 1 is switcher return path
  • SDI Input 2 is Live in for internal key over
  • Connect SDI out 2 to Input 1 for a keyed confidence monitor over live when you are in internal keying mode
  • Use SDI Input 1 for DVE or OCR
  • You should set SDI reference to Input 2 for internal keying
  • You should set SDI reference to Input 1 or internal for OCR/DVE
