Advantages of High Definition TVThere are many advantages of High definition TV or HDTV including clearer pictures, superior sound quality, progressive scanning and a wider viewing screen. For people looking to set up the ultimate home theater system, a widescreen television set is the number one choice. However, taking into account the numerous choices and options available, shopping for that new high definition TV can be confusing to say the least. The majority of HDTV sets that are currently available are big screen and are also generally expensive. Smaller screened televisions with digital capabilities are due to hit the market in 2007. Some estimates indicate that only around thirty million televisions in the United States have digital tuners, which means that there are some several hundred million sets that are not ready for the digital television revolution. So, what is the best way to cut through the confusion when choosing a high definition television. It is a good idea, when shopping for a new HDTV, to do your own research and get to know the product that you want to buy. HDTV setups can be very expensive, so make a point to shop around and ask lots of questions before parting with any money. Some of the larger sets available can run into thousands of dollars just for the television itself. At the present time, there are three methods of broadcasting digital television signals.
Standard definition and Enhanced definition can be broadcast with a traditional 4:3 square screen format or in a movie like widescreen format with reduced picture quality. High definition signals however, are all broadcast in wide screen format, which makes for a crisper, clearer picture. There are numerous different sizes and styles of HDTV sets to choose from. Consumers have the choice of plasma, LCD (liquid crystal display), DLP (digital light processing) or LCOS (liquid crystal on silicon) monitors. There are also projection displays to consider, which also come in LCD, DLP, and LCOS. Many people prefer the wall display monitor that either plasma or LCD offers. However, these types of sets are usually the more expensive of the high definition sets, especially the ones that are sized between forty and seventy inches. Lower down the price ladder, but equally as good, are LCD displays that are sized at forty two inches and under. So, what of the great benefits of using high definition television. For a start, HDTV has over twice the sharpness and clarity of analog TV broadcasts together with a far superior color resolution. Imperfections that are often seen on traditional television are another good reason why many prefer high definition to analog. With HDTV, problems such as double images from ghosting or multi-path, snow caused from a weak signal and picture sparkles from impulse noise are a thing of the past. These problems often seen on a conventional television broadcast just do not occur on high definition TV. High definition TV broadcasts have a screen resolution which is almost five times as sharp as conventional broadcasts. This is due to the fact that high definition has double the lines of resolution when compared to a traditional analog television set. While a traditional analog set can only display 525 lines (or 625 lines in the case of a PAL signal) of resolution, HDTV broadcasts can display 1080 horizontal lines of resolution. This makes a marked difference in the picture sharpness and quality. When it comes to big screen analog broadcasts, the picture is severely degraded because of the screen size and the lower resolution lines. |
