Can I have my game live streamed on a platform like YouTube and displayed on the iPad at the same time?

Yes, you can, provided that the Internet bandwidth at your arena is high enough. 

If the Internet bandwidth at your arena is high enough, yes, the Keemotion server can stream towards the Keemotion platforms (Sportshub + Keemotion Ipad App) and a platform like YouTube, at the same time.

Note:  By default, the option to stream towards your Keemotion iPad App and SportsHub is enabled in your "Stream Configuration" section in MyArena, and other live stream options are disabled. If you want to activate every streams, or if you want to choose a particular set of streams, please refer to that article.
