Android TV Live TV features

Besides the brief mention at the beginning of the keynote, I haven't read anything else about it. Has anyone else seen more details about the live TV features of Android TV? I'd be interested to see in particular what the experience is like and if there's any DVR capabilities built in, or UI components to that effect to suggest that OEMs may include this feature.

I use OTA with TiVo for live TV with DVR and guide, a Roku for streaming apps, and a Chromecast for.. well, just because. If the live TV features are robust enough, this could replace all three and become my single input device. It's all I ever wanted ;-)
