GRTV: CES double-bill

Toshiba 4K and the Sphero Robotic Ball.

Toshiba showed us its 4K screens, with a powerful upscaler that allows users to watch 1080p content on these UHD TVs, with some noticeable improvements.

Sphero is a game that lets you control a robotic ball with your smartphone. We've met Ian Bernstein, founder of Sphero, who has shown us this rolling toy and some apps to play with it.
