Notice the new rectangle with arrow shooting out of it? Yeah, that’s your new friend AirPlay. Airplay sends your pictures, audio, and video to the Apple TV, and audio to Airport Express and third-party speakers that support AirPlay.
In the iPod app the button to send your music via AirPlay. In other apps, the AirPlay icon is to the right of the volume control.
If you have the Apple TV, for video the button is to the right of the controller.
Once the video is playing, you’ll see this screen on your iPad.
In AirPlay-compatible apps, the button is to the right controller.
Tap it and you can choose your AirPlay enabled base station or speakers.
For video, it’s just like the iPad with the AirPlay button to the right of the controller.
And of course the dialog to remind you where your video is playing.
