Store it in iCloud. Watch it on Apple TV.
With iCloud, you can buy movies and TV shows on Apple TV and watch them on your iPad, iPhone, iPod touch, Mac, or PC. And vice versa. iCloud also stores your photos and pushes them wirelessly to all your devices — including your HDTV via Apple TV. It’s the easiest way to get instant access to your content, no matter which device you’re using.
iTunes Match.
If you’re an iTunes Match subscriber, you can access your entire music collection from iCloud — including songs you’ve imported from CDs — right from your Apple TV. Play your whole collection on Apple TV or any iPhone, iPad, iPod touch, or computer for just $24.99 a year. iTunes Match has an amazing scan-and-match feature: All the songs in your iTunes library are scanned and then matched with those available on the iTunes Store. Matched songs are instantly added to iCloud with no uploading needed. Any remaining songs are automatically uploaded from your computer to iCloud.
Photo Stream.
Uploading all the photos from a summer vacation or a big event is as easy as doing nothing at all. With Photo Stream in iCloud, your most recent 1000 photos automatically appear on all your devices — including Apple TV — no matter which device you used to take the picture. No syncing. No sending. Your photos are just there on your HDTV. For you, and everyone, to enjoy.
