Can I display text, RSS, or Twitter feeds using BrightAuthor:connected?

You can display static text, or an RSS feed using BrightAuthor:connected. You can use a Live Text state to overlay textual content on top of a video in a dedicated zone. You can also overlay text on top of an image by placing a Ticker zone on top of a Background Image zone. 

If you're using the Live Text feature, you can switch between one or more text fields with image backgrounds

Note: Text and RSS can be displayed as static, animated, or scrolling text within a Ticker Zone. You can only add a Live Text state to an Interactive presentation in an Image or VideoOrImage zone. 

To display Twitter content in BrightAuthor:connected, use a HTML page that embeds the Twitter content.
