It's no secret that people love live-streaming content to anyone who's willing to watch, whatever it may be. So, with this in mind, Comcast is introducing an app that will let its X1 subscribers record and push video streams from their mobile device to a TV in real-time. But there's more to it. The Xfinity Share application, available for iOS and Android, will also allow users to do the same with photos and videos from the camera roll. Better yet, you can share those (plus the livestreams) with other Comcast customers, so long as both the sender and receiver have a DVR-ready X1 set-top box and are subscribed to the Xfinity Triple Play package.
