Apple TV - The Apple TV is a device that allows consumers to stream iTunes data from computers to the their HD TVs. The device is what is known as a set-top box, because it connects to the TV (or is a box that sits on the top of the TV set).
The device syncs with the iTunes library on a computer in the same house and then allows the user to stream songs, videos, pictures, and other data that reside in that iTunes library (including both content bought from the iTunes Store and added in other ways) to the TV and entertainment center. The AppleTV only works with iTunes to sync and play media.
The connection used to stream content is wireless and requires a 802.11b/g wireless network.
The Apple TV is considered to be part of the iPod family of products because it requires the use of iTunes, and can use content purchased at the iTunes Store.
