(Telecompaper) Google is to unveil a set-top box at its developers conference 25 June. The company plans to show at least one small set-top box that resembles products like the Roku, Amazon's Fire TV, and Apple's Apple TV, two people who have seen the device told the Wall Street Journal. Google's device will carry another company's brand, but will be powered by Google's new Android TV software designed to play movies, games and other content on TVs. Users will be able to control the box using Android smartphones or tablets, and potentially other devices. The new TV platform is expected to include a focus on video games, including support for games that work seamlessly between mobile devices and TVs and split-screen services.
