Get an apple TV thingy and it will mirror what is on your ipad.
Sounds ok, do you 100% know it works before I shell out? Sky seem pretty effective with their controls on these types of things.
If it's skyGo you'll only get audio via Apple TV, assume same for other sky apps.
What if you open Skygo in a browser and then just maximise it? That is what I do with my laptop and intel widi and it works okay.
