I just noticed that my iPad Air can’t quite handles video with ~19Mbps video bitrates. Luckily, my Apple TV can. I’m pretty sure it’s not the network, since I’ve tried the iPad a few meters from the router.
My first guess is that, since the iPad and Apple TV have a A7 and A8 chip respectively, I need an iPad with at least A8 to handle the video. Would I be right, or is it more complicated than that?
