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.

If you want to activate every streams, or if you want to choose a particular set of streams, please refer to that article.
