Android TV won't be another device, instead it will be a platform that companies can use to bring streaming services to their televisions and set-top boxes. At least initially, Android TV is said to be all about online media services and Android video games, rather than trying to marry existing pay TV services with apps.
Google has been partnering with various services such as Netflix and Hulu for the launch. It's also expected to announce a few hardware partners.
GigaOm says the key focus of Android TV is simplicity.
Key to that is something the company has internally been calling Pano. The idea behind Pano is that apps can surface individual pieces of content right on the home screen in a card-like fashion so that users can browse movies, TV shows and other types of media as soon as they turn on an Android TV.
The cards can be browsed horizontally and each movie or TV show will link into a publisher's apps, letting the user start playback right away.
Originally, Android TV had an even more radical vision that would have removed app user interfaces altogether. Publishers would have provided data feeds that would have been display via tweakable templates. Apparently, publishers weren't too happy about that idea.
In April, leaked documents and screenshots revealed more about Android TV. Check those out here.
