This feature wasn’t described though Scot Forstall gave some highlight of this feature…. This feature will be used to play music, movies and show pictures on Apple TV from only iPad 2 via Wi-Fi (Peer to Peer).
It will support both landscape and portrait mode. We will be able to stream the whole interface on our Apple TV (HD TV), it means what ever we do on our iPad 2 it will run on Apple TV. This feature will be though very sexy for the regular FaceTime users, they will be able to have a video conference in a really good way.
