Supposedly, a smattering of support docs for Android TV were leaked from Google. These support docs lend credibility to the rumors that Google will be ready to launch Android TV to replace Google TV very soon.
Besides a streamlined interface, it looks like the Android TV remote is being redesigned as well, with a focus on navigating easily back and forth between menus. Here are some of the quotes found from Google in the documents,
"Android TV is an entertainment interface, not a computing platform. It’s all about finding and enjoying content with the least amount of friction. "[It will be] cinematic, fun, fluid, and fast."
They also added, "Access to content should be simple and magical," and, "Android TV is Android, optimized for the living room consumption experience on a TV screen." The docs also seem to suggest that Google is simplifying Android TV a great deal and removing some of the extraneous features found in Google TV.
The removed features are telephony, cameras, touchscreen support and near-field communication. Google is also working on creating ready-made interfaces so devs can just plug in games, shows, photos, music, films and more. Finally, the docs also seem to indicate that the interface of Android TV should never take more than three gestures to go from the homescreen to a new piece of content. Additionally, search is now secondary to intuitively understanding what you want and delivering it as soon as possible.
Still, universal search is an important feature and has some improvements. Supposedly, pressing Search on the controller allow you to search within individual apps as well. Check out the rest of the included docs' pics below in the thread.
