Steps

Hardware Connections

Laptop Connections
To physically connect components of the Live Book GFX system:
To ensure system functionality and communication between devices, physical connections of the system components should be made in the precise order described here.

  1. Connect the laptop power supply to the laptop.
  2. Connect the I/O box power supply to the 12-volt power connector on the left of the I/O Box, but do not power on the I/O box yet.
  3. Insert the USB connector on the wired mouse into a USB port on the laptop.
  4. Connect the Thunderbolt cable from the Thunderbolt connector on the I/O box to the Thunderbolt connector on the Live Book GFX.
  5. Contact AJT Systems support if the Thunderbolt cable requirement of your facility exceeds 6 feet.
  6. Power on the Live Book GFX laptop.
  7. Power on the I/O box.

Input/Output Box Connections

Video input and output connections are made through the BNC ports on the right side of the back of the I/O box.

In a control room or fully equipped production truck environment, the score bug is typically keyed over video at the switcher. You may opt to have the output of the switcher fed back to the Live Book GFX® system so that you can monitor the score bug over the video.

In a more streamlined remote situation, content from a camera feed goes directly to the I/O box and the score bug is internally keyed over the video. Video with the score bug is then output for uplink.

In addition to input and output, a reference signal (black burst or tri-level) should be connected to ensure smooth synchronization of video.

Use one of the following three sets of illustrated instructions to make the appropriate connections for your broadcast situation.

Downstream (switcher) Keying with Program Access

This configuration allows you to monitor the appearance of the score bug over video within the user interface.

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.

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.

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.downstream.jpg

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

Internal Keying

With this configuration, you can monitor the Score Bug that is internally keyed over the input video from within the user interface.

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.

Scoreboard Feed Connections

The Live Book GFX® system can receive data from the stadium scoreboard:

  • Via serial interface
  • Via TCP/IP

To connect the stadium clock feed via serial interface:

Use the serial to USB cable to connect to the available USB port on the Live Book GFX.

To connect the stadium clock via TCP/IP:

Connect the Live Book GFX to a network that has access to the TCP/IP Scoreboard feed.
