Quake® III on your TV with Cast Remote Display API- Google Developers Blog

This post introduces the Cast Remote Display API, which allows developers to extend their Android applications to a second screen, such as a TV, for an enhanced user experience. It demonstrates this capability by enabling Quake® III to be played on a TV, with the game rendering on the TV and the Android device acting as a controller. This leverages the Google Cast SDK to provide a second-screen experience.
