How Does HDTV Work?

In the world of HD, there are two basic choices in televisions - televisions that include the digital tuner, known as HDTVs, and televisions that use a separate digital tuner, known as HD Monitors. Current regulations require all 25" and larger televisions to include a digital tuner, so HD Monitors are normally found in some products under 25".

This resolution is broadcast by most broadcasters, and the image quality is nothing less than stunning.

These are televisions that include special circuits which eliminate the need for a separate cable set-top box. A slot for a CableCARD® is included in the back of the set.

Some cable operators may want to force you to take a set-top-box, which costs more per month, and is harder to use. By law, cable operators must give you a CableCARD if you request.
