Not so long ago, you needed your computer and portable devices to be directly connected to the speakers and screens you wanted to play their content on. AirPlay frees you from that need, allowing you to stream audio and video via Wi-Fi from your iTunes library to AirPlay-enabled devices--like Apple TV, audio systems from a variety of manufacturers that have AirPlay built-in, and systems connected to an AirPort Express on your Wi-Fi network. iTunes on the computer and the Music, Video, and other apps on the iPhone, iPad, and iPod touch automatically detect AirPlay-enabled devices on the local Wi-Fi network and present them for you to choose from. Tap or click it and pick the system you want to send the stream to. You can even pause while you're in one room, then tap AirPlay again to pick a different system in another room and tap Play.
