Enabling and Disabling HTML5 Graphics During a Live Broadcast

Spalk Support Team
Updated

Purpose

This feature allows production teams to quickly toggle HTML5 graphics on and off during a live broadcast without interrupting the video signal.

It’s especially useful when a broadcast starts and the HTML5 graphics don’t load correctly. This tool lets you refresh or change the HTML5 graphics mid-broadcast to resolve display issues.

When to Use This

  • If you need to change the graphics URL during a live event without stopping the broadcast.
  • If your graphics engine has an issue which is appearing on your broadcast.
  • If your broadcast starts but HTML5 graphics aren’t appearing.

Prerequisites

  • HTML5 Graphics URL: You’ll need the correct graphics URL for the event.

Steps to Enable/Disable HTML5 Graphics

1. Locate the HTML5 Graphics Controls

  • Navigate to the producer interface.
    • Dashboard > Commentators > Producer
  • Find the HTML5 graphics toggle option. This is near the Settings and Chat icons.

2. Disable HTML5 Graphics

  • Click the toggle or control to disable HTML5 graphics.
  • The current graphics overlay will disappear from the broadcast.

3. Enter a New Graphics URL (Optional)

  • If you want to load different graphics, paste a new HTML5 graphics URL.
  • To find the URL from the event setup:
    1. Go to Edit Event.
    2. Locate the Graphics URL field.
    3. Copy the existing URL.

4. Enable HTML5 Graphics

  • Click the toggle or control again to enable HTML5 graphics.
  • The broadcast will now display the graphics from the specified URL.

Example Use Case

If your broadcast starts but halfway through the HTML5 graphics engine crashes, and graphics are stuck.

  1. Disable the graphics overlay.
  2. Re-enable it with the same URL (or a corrected one).
  3. This forces the system to reload the overlay without stopping the video feed.

Troubleshooting

  • If the problem persists after toggling, contact your Spalk representative for further investigation.
  • This process can also be performed by any authorized organisation members.

Tip: This process works in real time and does not interrupt the video signal, making it safe to use during live coverage.
