Question

  • How to configure a Live Book GFX® system using internal key?

Environment

  • Product Family: Software and Controllers
  • Product: Live Book SportApp
  • Component:  Internal key wire diagram
  • Control System: AJT Systems a Division of Daktronics
With this configuration, you can monitor the Score Bug that is internally keyed over the input video from within the user interface.


Steps

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

To make input/output connections for internal keying to prepare for direct uplink of video with score bug:

  1. Connect the camera feed to Input 2.
  2. Connect Output 2 to Input 1 so that you can monitor the program output of the system.
  3. Connect Output 1 to an encoder or other device for uplink.
  4. Optionally, 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.

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
