Multiscreen video app casting the TV concept

In this prototype I use 2 devices and 2 prototypes. On the phone is the video browsing app and on the iPad is the viewing app. Using ProtoPie's ability to connect multiple prototypes together across multiple devices using messages I flick the video I want to watch to the iPad and it starts casting. The iPhone app then turns into a remote control for the content as well as showing other useful information.
