What is Apple TV?
First things first: Apple TV isn't an actual television. It's an Apple media player that allows you to stream your favorite Internet apps and digital content on your current TV. In effect, Apple TV turns the TV you already own into a Web-connected smart TV.
Streaming media players are each compatible with a different selection of popular apps and services like Netflix, YouTube and HBO GO. Apple TV, however, is the only one that gives you access to your iTunes library. So if you use Apple devices or purchase content through the iTunes app, buying an Apple TV is the best way to ensure you'll be able to stream your content on the big screen.
Apple TV can help you finally get rid of your monthly cable or satellite TV bill. By using Apple TV apps for Internet-based media, along with a TV antenna for local channels, you can watch everything from the nightly news to movies, premium shows and more for less than what you're paying for cable.
How does Apple TV work?
Apple TV plugs into your HDTV's HDMI port and connects to your home Internet network, either wirelessly or with an Ethernet cable. Once you see the interface on your screen, you can use the Apple TV remote to browse apps, content and other features just like you would on a set-top cable box. In addition to Apple's pre-installed apps, you can choose from hundreds of popular video, gaming and music apps to download and play.
Plus, if you have an iPhone or iPad, you can download the AirPlay app from the App Store and use it to stream photos, video and music directly from your device to your TV. You can also use it to mirror your device's screen onto your TV so you can browse the Internet, play games and more on a larger display.
