Although most everyone has now heard of HDTV or High Definition Television, some confusion remains. This article addresses some of these frequently asked questions, helping to clear up the subject. Keep in mind that high definition television is the latest and greatest transmission technology that will forever change the way we view television. With this type of special programming becoming mandated in February of 2009, it is even more important to get answers to the frequently asked questions.

o Is digital and High Definition the same thing? - The answer is a little confusing but we will explain. You see, digital cable is available in three unique formats that include standard, enhanced, and high definition. High definition is the best offering available through cable. With standard digital cable, you get a 480i resolution, with enhanced, 480p, and high definition is either 720p or 1080i.

o What are the other options of EDTV and SDTV? - This is another of the frequently asked questions seen most often. With high definition, you would be able to enjoy a widescreen aspect ratio of 16:9. However, with EDTV or Enhanced Television and SDTV, which is Standard Television, you still have the option of watching your show in widescreen but without a designated aspect ratio.

o Is a high definition television set a requirement once the mandate goes into effect? - Of all frequently asked questions, this is on everyone's mind. Remember that not everything you watch on television is an offering under high definition. Additionally, to enjoy programming, you would be required to pay more. However, if you still want to update your standard television to HDTV, you can buy a new set or simply choose other, less expensive options that will still provide great pictures and sound such as EDTV or SDTV. Then, for people needing to upgrade from a television set using an antenna, a digital tuner box could be used.

o If I wanted to buy a new HDTV television, how much would I expect to pay? - The cost for a high definition television ranges dramatically, depending primarily on size and features. For instance, you could choose a small, 14 or 20-inch set with few features for about $500 to $700 whereas a big screen of 40 to 52 inches and one loaded with features could cost from $6,000 up to $20,000!

o Are high definition services purchased through the satellite or cable company? - The answer to this frequently asked question is no. If you want to enjoy high definition, you would need to go through a company that provides 100% digital, but for a fee. Now, you can save money each month by using a digital tuner box instead or simply enjoy the limited channels provided through satellite or cable.

o When it comes to special programming, what does high definition offer? - The answer is that it depends on the station, as well as the high definition provider. However, the more prominent channels that use digital transmission would provide programming through HBO, TNT, ESPN, and Discovery.

o What is the difference in resolution of 720p and 1080i? - For you to see a picture on your television set, the image is produced with a large number of scanned, lines, each working independently. The number of resolution lines will depend on the type of digital television you have. With 720p, your television has 720 scanned lines, working progressively. Then with 1080i, the number of scanned lines increases to 1,080.
