Device manufacturers, such as TiVo and Ceton, manufacture devices for retail that can use a CableCARD to access Xfinity TV service.
If you purchased a CableCARD-compatible cable TV Box from a reseller, it can also be used to access Xfinity TV service. (See Off-Market TV Boxes for more information.)
If you elect to use your customer-owned devices instead of renting a Comcast TV Box or TV Adapter, you must obtain a CableCARD from Comcast.
Note: Whether you use a customer-owned device, a Comcast TV Box or a TV Adapter for Xfinity TV on additional TVs, you'll be charged a Digital Service to Additional TV/TV Adapter Service to Additional TV fee for each additional TV.
CableCARD Frequently Asked Questions
What is a CableCARD?
A CableCARD is a device roughly the size of a credit card that can be used with a compatible third-party device to access Xfinity TV services. Comcast supports CableCARD-compatible devices such as TiVo, Ceton or Silicondust. (This is a non-exhaustive list.)
If you subscribe to Xfinity TV service, you have the option of purchasing a third-party CableCARD-compatible device from a retailer. You can also purchase a CableCARD-compatible cable TV Box from a reseller. This device can also be used to access limited Xfinity TV services. (See about Off-Market TV Boxes for more information.)
If you choose to use a customer-owned device instead of renting a Comcast TV Box or TV Adapter, you must obtain a CableCARD from Comcast.
Once I get a CableCARD Getting Started kit, how do I activate my CableCARD?
Once you receive your CableCARD Getting Started kit, go to the Xfinity CableCARD activation and pairing tool at cablecardactivation.xsp.comcast.net/ and refer to these easy-to-follow instructions on pairing/activating your CableCARD.
Why is Comcast offering CableCARDs?
Comcast is committed to working with manufacturers of retail devices, including manufacturers of CableCARD devices, in order to provide you with more choices to access and enjoy Xfinity TV services. Comcast will continue to support retail CableCARD-compatible devices well into the future.
For any questions about your CableCARD, please call 1-877-405-2298.
If I have a CableCARD device, do I still need my Comcast TV Box or TV Adapter to get Xfinity TV?
You only need a CableCARD device, Comcast TV Box or TV Adapter for each TV connected to Xfinity TV service.
Can I access the same features and services with a CableCARD that I currently enjoy with my digital cable service?
Retail devices that support CableCARDs (like TiVo) have their own features, which may include on-screen program guides and DVR service (if supported, DVR service may require a separate subscription) that are supported by the retail device manufacturer. All linear (non-IP) channels that are part of your Xfinity TV service will be available. Some retail devices also support additional services*. Please refer to your owner's manual or manufacturer's website for additional information on your device.
For more information on TiVo devices, please visit the TiVo website.
Do CableCARDs offer Parental Controls?
Currently CableCARDs don't have Parental Control functionality, although Comcast does pass V-chip data to the CableCARD device. V-chip is a generic term for technology used in television set receivers which allows the blocking of programs by ratings that are content-based.
Please review the owner's manual for your CableCARD device to learn what Parental Control functionality may be available.
Why does my On-Screen Guide look different from the digital cable TV Box guide?
CableCARD-compatible retail devices use a guide provided by the device manufacturer, which is different from the guide provided by Comcast. As a result, the guide content from the manufacturer may not always match Comcast's guide. For more information about your guide functionality and features, please consult the owner's manual for your CableCARD-compatible device.
Will I be charged to use a CableCARD?
In most cases, a CableCARD in a customer-owned retail CableCARD device is free as long as there are no other pieces of equipment on the account.
What are the fees associated with Service to Additional TV outlets?
Whether you use a customer-owned device, a Comcast TV Box or a TV Adapter for Xfinity TV on additional TVs, you'll be charged a Digital Service to Additional TV/TV Adapter Service to Additional TV fee for each additional TV if you subscribe to an Xfinity TV service above Limited Basic.
Why am I not able to view all of the Xfinity TV content that I subscribe to if I remove my CableCARD from the host device or move it to another device?
If you remove the CableCARD from its host device, the CableCARD will possibly be unpaired from that device. If this occurs and you lose some or all of your Xfinity TV content, you'll need to call 1-877-405-2298 to re-pair and reactivate the unit.
