MacRumors points to a new service by Comcast which appears to mirror the functionality of a Slingbox or EyeTV, allowing a cable box to ‘Sling’ the video to an iPod around the house.
Currently, Xfinity customers can use the Xfinity TV app to watch On Demand programming, search TV listings, and schedule DVR recordings.
There is no indication of release dates or availability, but AnyPlay will be available in limited markets at first, and spreading to all Comcast customers eventually.
This is in contrast to their current app which streams on-Demand video over the internet to iPads which are on Comcast IP addresses with adjacent cable service. Other US cable companies like Time Warner and Optimum offer Apps which stream many channels.
Check the red area above right for why this isn’t going to be very fantastic.
If you want this kind of functionality right now, but not tied to a cable company and their stipulations (and the ability to stream to devices outside your home without an extra cost), look into Slingboxes or El Gato’s EyeTV.
