Many people wanna stream files through Airplay, but have no idea how to do it. This post show you how to use Airplay on your new iPad with an Apple TV or Airport Express.

One of the most understated features of Apple’s iOS 5 is Airplay. Airplay allows you to mirror your iPad’s display with your TV, as well as stream video and music from your iOS device.

In order to use Airplay you need to have an Apple TV (2nd or 3rd Gen) or an Airport Express (audio streaming only).

1. Ensure that either your Apple TV or Airport Express has been fully set up and is connected to the same wifi network as your iPad.

2. Double click the home button, the multitasking tray should open.

3. Swipe left until the last pane of the multitasking tray, just to the right of the audio controls you should notice the small Airplay icon (it looks like a TV with a triangle inside).

4. From the Airplay menu you can select where you wish to mirror or stream content, here you should see either your Apple TV or Airport Express devices. Devices which can receive full Airplay streaming (mirroring, video and audio) will have a TV icon next to them, whilst those just capable of audio streaming will have a small speaker. Simply tap one of those devices.

Note: If you wish to mirror your iPad’s display then tap on the mirroring on/off toggle underneath your listed device.

5. You are now using Airplay and your content should begin to stream to your selected device. To turn off Airplay repeat steps 2-4 and simply tap the connected device to stop Airplay.

For media files that can't supported by new iPad 3, you may use the iPad video converter to deal with.
