AirPlay lets you stream video and mirror your display from iPhone, iPad, or Mac to Apple TV. It also lets you stream audio to Apple TV and any compatible speakers, including those connected to an AirPort Express router. If you're on the same Wi-Fi network, AirPlay simply connects and starts streaming. If you're not on the same network, AirPlay can use point-to-point Wi-Fi to stream. That makes AirPlay great for entertainment, education, and enterprise — just tap a button, choose a target, and watch your show or run your presentation.

How to AirPlay video from your iPhone or iPad

You can AirPlay any video simply by mirroring your screen. Some video players, like YouTube, will even let you AirPlay right from the video pane (there'll be an AirPlay button on the bottom right of the video window when you tap it).

Swipe down from the top right corner of the screen to bring up Control Center. Tap Screen Mirroring. Tap the device you'd like to AirPlay to.

If you're not on the same Wi-Fi network as the Apple TV you're targeting — for example, if you're at a meeting — the Apple TV will display a code and require you to enter it on your iPhone or iPad before streaming over point-to-point Wi-Fi.

How to stop AirPlay video on your iPhone and iPad

When you want to stop AirPlay, it's just as easy.

How to AirPlay audio from your iPhone or iPad

Swipe down from the top right corner of the screen to bring up Control Center. Tap the AirPlay button on the Now Playing Widget. Tap the device you'd like to AirPlay to.
