Provided by your cable service provider, CableCARDs plug directly into the back of your digital television.

Usually costs less than a set-top box. Disadvantages No video-on-demand or interactive TV services. Features are inconsistent. Not all have parental controls. All televisions equipped with a CableCARD slot have a built-in ATSC digital tuner, which means the TV is digital cable-ready.

If there is no sales information, look on the back or side of the television for the card slot.

In most cases, the cable company requires a service call to configure the card to the television. CableCARD technology is only available for cable subscribers.
