Mixing videos and text when the live program is running

Can we for example:

Add a photo on one silde of a live video then send it to media server and therfore our viewers be able to see the photo on one side of live video

Or

Can we add one or more small videos on one silde of a live video then send it to media server and therfore our viewers be able to see the small videos on one side of live video

And I like to insert Text Messages below of the main screen when the live program is running.

Please advise, thanks
