Hello, and welcome to the wonderful world of time travel. Technology is a
growing part of our society today, and it is going to be very important part of our future. I am going to show you what technology is doing for television from now, into the next century. Sit back, relax, and buckle up as we embark on our journey through time.
To start off, HDTV(high definition television) is what we have to look forward to in the next three to five years. Now, you are probably asking yourself what is HDTV? HDTV is an all-digital TV broadcast signal that delivers high-resolution, wide-screen picture, and six channels of digital sound. Though computer experts and scientists are working on a more advanced 3D and polygraphic television, it is too far away to tell when it will be done, and how much it can do. As of now, twenty-six stations have filed their
intentions to begin digital broadcasts. Digital television sets are on sale now, though the price is between five to ten thousand dollars. There is a converter box on sale as well that you hook up to your TV, and it changes the regular signal to digital to your TV screen you have at home now. That is approximately three to six thousand dollars. You are probably saying to yourself at this point, �Other than being more expensive, what am I
getting out of a HDTV that I am not getting from the TV at home? To start with, as of now, we use 525 lines of resolution,(makes up the screen, with colors) where HDTV has anywhere from 720 to 1080 (Sobel 73). Next, is the difference between the picture screens. The HDTV has a width to height ratio of 16:9. The average TV now is 4:3. Other than getting a bigger screen with a great picture, you are getting digital sound. HDTV broadcasts will be encoded with Dolby Digital (AC-3) audio, featuring 6 separate audio tracks. Each track can be sent to a different speaker allowing detailing and realistic sound (Sobel 74).
Now, as the tour rolls on, we take a look to see what is in store for us in the near future. By November of 1999, the FCC is requiring that the top 30 markets (cities) join the digital broadcasts. By that time, the average price will drop dramatically(Zwirn interview). On average, the first HDTVs made will be between twenty-four to sixty-four inches. The fact is, the more markets that join digital broadcasts, the less the price will be for an average HDTV(Veilluex The Selling of DTV).
The make of the HDTV is very complex, though it can be easy to understand. First, the screens are much wider and more flat. In addition to the obvious weight and and size of the picture, the resolution and luminance...
