Users can search regular TV and On Demand content, change the channel, set DVR recordings, and create a list of favorite programs - all from their mobile touch screens.
In December, subscribers will also be able to watch Xfinity TV content directly on the iPad.
Technical requirements include a minimum of iOS 4, a compatible cable/set-top box for DVR control, a Comcast ID and an Internet connection. Conveniently, the last one can either be 3G or Wi-Fi.
The Xfinity TV app will be available to download from the iTunes App Store this week for free. An Android version is coming soon.
