CG created in HTML can be overlaid on the streaming video as a layer.

*Only RTMP is supported as a distribution protocol.

Follow the steps below to enable and customize it.

1. Turn on Web CG

This will enable the CG layer function.

2. Configure Web CG Settings

Once turned ON, open [Web CG Settings] in the same menu and enter/adjust the following items.

・URL

Specify the public URL of the HTML of the score CG.

・Redraw Interval

Set the time (in seconds) it takes for new scores and text to be reflected.

→ For example, if you set it to 2, the latest CG will be drawn every 2 seconds.

・Refresh Interval

Sets the interval (in minutes) to forcibly reload the entire page in the rare event that CG is not loaded correctly.
