 
HDTV is exciting — but it can also be confusing. HDTV and other forms of Digital Television (DTV) present consumers and broadcasters with a number of configuration issues related to broadcasting, receiving, and viewing DTV and HDTV content.
DTV and HDTV broadcasts are offered in a variety of vertical resolutions, aspect ratios, and scan modes. Unfortunately, not all HD televisions support all DTV broadcast formats, and DTV receivers/decoders are forced to perform the appropriate conversions.
HDTV vs. HD-ready
True HD televisions — also known as "integrated HD" — have an HD tuner built right in. Just plug in a High-Definition broadcast source like digital cable, and you're set. The only drawback is the price; integrated HDTV sets can cost thousands of dollars.
HD-ready sets, on the other hand, are more affordable, and can display both standard and High-Definition programming. You'll need an external HD tuner, in addition to your digital cable or satellite receiver. Motorola's DCT6200 HD Digital Cable Receiver integrates an HD tuner and digital cable receiver into one convenient unit.

Enhanced Definition
While shopping, you may notice some TVs described as Enhanced Definition (EDTV). As the name implies, these TVs can provide a better picture by supporting the 480p, widescreen, progressive scan resolution mode. This can result in sharper video especially when used with progressive scan DVD players.
However, this is not High-Definition, as the lines of resolution are the same as Standard Definition (480). If you want HDTV, look for a TV that is clearly marked High-Definition and supports either the 720p and/or 1080i resolution modes.
