Google TV is a software platform for set-top boxes and HDTVs based on the Android operating system and co-developed by Google, Intel, Sony and Logitech. The project was officially announced by Google and its partners on May 20, 2010 (Wikipedia)
It's a software platform...
You know how the Nexus One is a piece of hardware by HTC that runs Android, a piece of software by Google? That's how Google TV will work. At its heart, Google TV is a platform. It's software. Hardware makers will need to step up to use it in their devices.
...that Logitech, Sony and DISH will support...
Right now, there are three places we'll see Google TV: a set top box by Logitech, Sony televisions (and one Blu-ray player) and an upcoming DISH box. They all share the following common specs: An Atom (or better) processor, discrete GPU, HDMI-out, Bluetooth, IR (with a transmitting "blaster"), Wi-Fi, and Ethernet, all while supporting a keyboard and a pointing device, as well as more traditional remotes such as Logitech's Harmony universals
...works with existing cable/satellite box...
Equipped with an IR blaster to change channels, Google TV can sit on top of your existing infrastructure. So while new hardware is in the works, it should be compatible with whatever you're using now—cable or satellite boxes, with all relevant subscriptions.
...that works just like a Google search...
When you start any Google TV device, you're greeted by a simple search bar. You type what you'd like to watch. That can be a television station, allowing you to select and tune that channel. Or it can be a show, which will point you to places you can find the show—be that through a cable subscription channel, Netflix or somewhere on the web.
...that combines the web with TV...
So say you want to watch something that only exists on Amazon's streaming service. You'll be taken to Amazon's webpage through Chrome, where the video will stream. Random websites might look crumby on your television, of course, which is why Google asks that sites optimize for Google TV (full SDKs available in 2011). With this mix of web and television, you can also view multiple sources of information in multiple panes. So you can watch the Sox game on one part of your screen while reading Paul Konerko's realtime stats in another.
..that combines your TV with your phone...
Thanks to required Google TV hardware specs like Bluetooth and Wi-Fi, you'll be able to load a webpage on your Android phone and beam it to your TV. You can also use your Android phone's voice recognition, effectively making it possible to change channels or search for shows just by talking.
...that runs apps...
Oh, Google TV includes complete access to the Android App Store. And Google suspects that most any app will run fine on the platform, though those designed with cellphone-specific hardware in mind might not work with 1:1 compatibility. But when the SDK is available in 2011, we can expect Google TV-specific apps, too.
...that still has some tricks up its sleeve...
As of yet, Google has barely scratched the surface of what this seemingly unparalleled integration of TV and web can do, but they demoed one wow-worthy function: firing closed captioning through Google Translate—translating a program in real time. Just try to tell us that's not neat. (We will translate any negative comments into a language we don't understand—in real time.)
