I slowly realized that these 2 things are different but I'm not sure how. I believe the usual black boxes you see on Amazon are just Android OS. So what are the extra capabilities you get with Android TV? Seem like it has a specialized launcher and voice commands?
^Sorry ^for ^the ^dumb ^question!
Not a dumb question. Many people are confused and its unfortunate that these android "tv" boxes existed before Google decided to rebrand "Google TV" to "Android TV"
Here is Android TV
Biggest difference to me is the UI. Leanback UI is sexy and appropriate for the big screen. App shortcuts are nice big tiles with proper sized font. UI navigation is conducive to using a simple d-pad remote.
In addition to a beautiful 10ft interface, there is global search, which allows you to search apps for content right from the main screen (provided individual apps develop this integration). This global search can be done via voice and is my preferred method of use. Additionally, there is a global recommendations bar on the home screen that shows content from apps that have integrated it. You can select the content from here and jump right into the action.
Theres also a great, highly underutilized app called "Live Channels." The name is a bit of a misnomer. Its not necessarily live tv, but the UI is similar to what you would find in a regular cable experience. With this app, content is aggregated from participating apps to create "channels" and present them in a traditional tv guide UI. Again, the focus here is ease of access to your content.
And the final big feature I will touch on is built-in google cast functionality. Basically, every official Android TV device (none of boxes you see on Amazon) can be used just like you would use a Chromecast device. This is great for apps/developers that have not gotten around to updating their apps to support the Leanback UI in Android TV.
Really, it comes down to it that its just a better, smoother more optimized experience for typical use with a TV.
