A CableCARD can be used with TiVo or CableCARD-ready televisions to access our video services without leasing one of our digital converters or adapters.
What will happen
Using a CableCARD device instead of a Comcast digital converter means you will only be able to receive one-way digital cable channels and not be able to receive XFINITY On Demand, pay-per-view, or the interactive programming guide.
If you already have a digital-cable-ready HDTV set, no special cable box is required to receive HD signals for broadcast channels. These TVs will also receive any XFINITY TV channels that you currently subscribe to (e.g. ESPN, HBO, or Showtime).
You can also get Comcast service for your digital-ready TV or TiVo Series 3 Digital Media Recorder. However, to get the full range of our digital cable features, including XFINITY On Demand, Pay-Per-View, or the Comcast On-Screen Program Guide, you will need to use a digital cable box.
Note: XFINITY On Demand HDTV services requires the use of a XFINITY TV cable box.
