Downstream (switcher) Keying without Program Access

 This configuration allows you to monitor the appearance of the score bug only, without video, within the user interface.

Steps

First, reference: "How do I physically connect components of the LIVEBOOK GFX system?"

To make input/output connections for downstream (switcher) keying without program access:

  1. Connect Output 1 of the I/O box to a distribution amplifier.
  2. Connect Output 1 from the distribution amplifier to Input 1 of the I/O box.
  3. Connect Output 2 from the distribution amplifier as Fill to the switcher.
  4. Connect Output 2 from the I/O box as Key to the switcher.
  5. 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 signal flow 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 yu 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
