The company announced its news, as expected, at its annual developer conference in San Francisco.
A variety of devices, from smartphones to tablets to video game controllers, can be used to control Android TV.
Android TV can interface with both live and streaming TV. While watching live channels, viewers can use Android TV to access an EPG or scroll through channels. If they wish to access streaming apps instead, a Home button will take them back to a more traditional Android interface, where they can open a streaming programme or launch a search.
Android TV lets users broadcast content to their TV, as well as search a grid of popular content, apps, and games. Voice search and Google Knowledge Graph are also enabled for Android TV, which means people can just talk to the TV set and do a voice search for instant results.
Apps designed specifically for Android TV will arrive in the fall, alongside the latest version of the Android OS
In related news, Google also announced the addition of a new feature for Chromecast called Backdrop which can run feeds of photos, news, weather, or art while people are not using the device. The company said Chromecast is a huge success, being in the top five of electronic devices sold on Amazon.
