Guide Note:

High-definition television is the latest advancement in home theater and entertainment center technology. The concept is to provide the user with the brightest, clearest and sharpest of video images with the highest possible resolution. It provides a more distinct viewing experience over conventional television sets. By February 17, 2009, all television programming provided by both the traditional over-the-air providers and cable network providers will broadcast in high-definition. This means that many consumers will need to either purchase some form of digital television or have a converter added to their existing television set.

I want my HDTV

In the simplest of explanations, the biggest advantage to the consumer of purchasing an HDTV is that is has a significant difference in the number of lines of resolution over standard television sets. So, the picture that is broadcast on the screen is much crisper and sharper, with the contrasts in color becoming much more obvious to the naked eye. Furthermore, most broadcasts today from over-the-air networks like ABC, CBS, FOX and NBC, as well as larger cable channels, are strictly in high definition. This means that not only is the picture availability significant over previously aired analog broadcasts, but the audio capabilities (with most in Dolby Digital surround sound) are far more enhanced than previously available. It's also important to note that HDTV and digital television are not the same thing. HDTV is one of several digital television formats that are available, though currently the most popular and widespread.
