The Advancement Of HDTV
Television, sometimes spelled to television or telly, is an electrical media used for broadcasting moving images either in color, black and white, or in two or more dimensions and with sound. The word television can also refer to the technology of broadcasting, a single television unit, or the medium of visual communication. Moving images are transmitted through a signal transmitted via electrical or radio signals. There are various media which have been used as a means of transferring pictures and other information to a viewer such as television, film, newsprint, newspaper, audio, and now digital information. This medium has enabled people all over the world to communicate, educate, and entertain themselves. In the past, television was largely a major source of entertainment and the means of communication.
Television in the past was viewed using a set that was placed in front of a TV set. This was a very large screen which was able to rotate and change colors. The screen was divided by a cord from the back so that it could be viewed easily from any angle. Music was played from a small radio which was connected to the television. This radio often featured music from a variety of different sources including radio stations, music videos, talk shows, from the television sets on channels which were selected by the viewer, or came from the programming disks provided by the cable company. Color was also an important aspect of broadcasting as black and white pictures were more popular than anything else.
With the advancement of technology and the invention of the wide-screen LCD or flat panel monitor, broadcasting has taken a significant turn towards the high definition realm which features far greater dimensions and improved picture quality. HDTV is the term commonly used to describe these high quality broadcasts. HDTV broadcasts an image as a sequence of pixels that is displayed in full color. This is one reason why HDTV broadcasts are typically twice as clear as a traditional TV broadcast.
While the introduction of the LCD monitor changed the way television was viewed it did not really change how people watched television. The VCR was widely used as a means of recording TV for home use. When the first AMF TV tuner was produced and sold it quickly replaced VCR’s everywhere. VCR’s were often forgotten about when satellite TV arrived and people were still watching their analog TV’s. People were quickly put off HDTV when they discovered the quality of their analog TV signal being lost while watching an HDTV show.
As with every new technology there have been a few cons that have been pointed out. One problem that is frequently brought up is the fact that HDTV is priced more than CRT. In order to make up this difference a number of manufacturers have chosen not to make the bigger sized screens found in HDTV’s. Many of the manufacturers of HDTV’s have resorted to producing the same sized screens in an effort to keep their costs down.
Another problem encountered with the development of HDTV was the fact that DVD’s became obsolete because of the amount of data they could now carry. This meant that instead of just being able to watch one movie you were now able to watch over 50 movies on one set of TV’s. This also meant that the picture quality on HDTV’s started to deteriorate at a much quicker rate. The popularity of HDTV has faded because of these two problems. However, today we are more likely to be watching an HDTV show rather than a regular TV series.
