HDTV is a term much bandied about by the media. We are constantly asked if we are ‘digital ready’ and encouraged to try as a feature when purchasing a new TV. But what exactly is it?
HDTV stands for High Definition Television. This is a digital transmission system that has a higher resolution than standard television systems, resulting in better image quality. As part of this transmission system uses digital television signals, which require the use of lower bandwidth than the older analog systems. HDTV even though many consider a new sentence, the technology has actually been in operation for about 20 years, and the first broadcast in high definition to the public occurred in the United States in 1996.
Customer Benefits
All the technical aside, the main thing many people simply want to know if you need to buy a digital television. In short, yes it is. The advantages of a digital set includes an aspect ratio better, a higher level of resolution and frame rates than analog TV. All these combine to produce a better image quality, and this is particularly noticeable when watching widescreen movies on TV.
In 1999 the Federal Communications Commission (FCC) decided that broadcasting would be the new standard for digital television, and that analogue transmissions will be gradually eliminated over the next few years – more or less the same way that DVD players have gradually replaced VCRs.
Should I buy an HDTV?
It makes little sense to buy an analog television, as the analogue transmissions are beginning to cease. In the United States this happened in June 2009, with many other countries as well as to do the same in the coming years. This means that it is a straight choice between digital and HDTV.
To summarize the difference: All HDTV is digital, but not all digital HDTV. High definition is the best quality of digital currently available, although the actual difference in quality is currently visible only in certain transmissions. It ‘also the next standard in film technology, including the purchase of an HDTV, you will be protected against technological change for at least the next few years.
