What is a CableCARD decoder?
A CableCARD decoder is small card that allows a digital TV or set top box to receive Digital Cable programming from your cable provider. It’s about the size of a thick credit card, and fits into a special slot built into the TiVo HD box. To receive two digital cable channels at the same time, the TiVo HD DVR will require either one (1) Multi-stream CableCARD or two (2) Single-stream CableCARDs. You will need to contact your cable provider to request CableCARD decoders. All major cable companies are FCC mandated to provide CableCARDs to their digital cable subscribers. Some cable companies offer CableCARDs for free and others charge a small monthly fee.
