HDTV - The Reason is Crystal Clear
from: George PhillipsJust take a look at the amazing picture which HDTV produces and you will know what makes it so much better than analog transmissions. HDTV makes it seem like you can jump into the screen. Colors, detail and resolution are vibrantly displayed with much more clarity and hue. Even though broadcasting stations, film and TV producers, and makers of TVs, DVD players and cable boxes are all trying to smooth out their disagreements about standardizing high definition technology; people are enjoying the benefits of owning HD-capable TVs, and of watching HDTV broadcasts. Broadcasters are making sure that their HD stations are showing the most visually aesthetic shows they can. Sports, nature shows, aerial flights through canyons and various terrain, and artfully crafted, computer-generated shows are being used to show off the crystal elements of high definition television.
HDTV technology can still be transmitted through regular analog means, so some of the annoyances of regular antenna-based TV can remain. However, with an HD-capable TV, one can still see the difference. Analog transmissions are based on the same technology which radios use. This accounts for the static, fuzziness and other annoyances which most of us remember when growing up. Viewers, who get their TV transmissions from these analog signals, often refer to the pesky interference as ghosts, snow or static. NTSC is the official name for this type of signal in the United States. The strange thing about NTSC is that the technology was created for strictly black and white TV broadcasts. When color was introduced into the system producers renamed the acronym "never twice the same color," rather than national television system committee." The truth is plain to see. NTSC's use of analog technology in TV broadcasting is out of date.
HDTV stands for "high definition television" and is based on digital technology. There is HDTV programming and also TVs which feature built-in HDTV capabilities. Because of internal wars between analog, cable, and other forms of data transfer, HDTV has not been accepted across the board. Some companies are worried about technology moving too fast for them to keep up, so they end up doing nothing at all. However, for those who have HDTV, they do not need anyone to tell them that they are looking at five times the better picture than they are through their analog or regular cable programming. Whether you have DIRECTV, HD-Capable or regular over-the-air analog, you will be able to use your HD-capable monitor.
HDTV lets one view images the wide screen way in which they were usually filmed. This boils down to a pure translation of the image from the broadcaster to your TV. You are getting the full image as well as more of it. The typical analog image is based on only 525 to 625 lines of image. HDTV transmissions give one up to 1080 lines of resolution. Those extra lines make an image look like it is real. Because of the number of pixels that are used in high definition technology, a picture can look like it is ten times better than an analog one.
The crystal clear elements of HDTV are not just visual. It seems silly to have a great image, but bad quality sound. The technology of HDTV matches this need by using digital surround sound. This is something which analog TV was never able to offer.
HDTV is also highly compatible with computer technology. Media is moving more and more toward the idea of integration. This means that one's music, TV, camera, DVD, and computer will all be combined into one unit or center, or at least, be completely compatible. Everyone has had experiences with trying to get one media out of another. HDTV receivers are integrating media through a technology called MPEG-2, which is basically how the data compresses itself into bandwidths. As TV stations catch up their equipment to the FCC's requirement that everyone has HDTV capabilities by 2007, more and more ways to further use the high definition technology will be possible.
HDTV offers solutions to analog's problems on three levels. It has combined resolution, wide screen, and Dolby sound into a crystal clear transmission. The HDTV technology has surpassed analog and its regular, digital origins.
Important Notice Concerning DTV and HDTV: Although many TV systems have already complied with earlier rulings for changing all transmission to digital TV, there still is doubt as to when overall compliance will be reached. Earlier it was scheduled for late 2006, but it is doubtful if this happens.
