Google Fiber (NASDAQ:GOOG) is adding a media casting capability based on its Chromecast streaming media technology to its Fiber TV Box. Dubbed Google Cast, the capability is app-based and designed to let users access content from Google's own video service, OTT video and other media such as music, and social and user-generated media.

The user connects a compatible mobile device or laptop to Fiber Wi-Fi, then taps the Cast button from the apps to send the mobile content to the TV. The company plans to start rolling out Google Cast on Fiber TV to all of its TV subscribers in the coming weeks.
