HDTV (also known as high-definition television) has created quite a splash in today’s world of home entertainment. HDTV has amazing visual clarity as well as the unique sound of digital that is without a doubt, unequalled by anything else. The broadcasting of the signals of high-definition television has a much higher resolution and is more advanced than more traditional television signals (including NTSC, PAL and SECAM). To look back in history, “high-definition television” was also a term used to relate to standards of television that were put in place during the 1930′s to replace the television systems that were more elementary and experimental in nature. Image means everything in the HDTV world.
HDTV is broadcast in digital format (with the exception of the earlier analog formats that were prevalent in both Europe and Japan). The creation and introduction of HDTV is often thought to go hand in hand with the beginnings of DTV, or what is known as digital television.
To return to the mention of Japan, HDTV was in the works for a number of decades but once it was implemented it took place in an analog format. The system they once avidly subscribed to is not in the least compatible with the necessary standards that digital dictates. In Japan the broadcasting of HDTV began in December 2003 and was made possible by ISDB-T. In fact at the present time, Japan is the only country that broadcasts its services in HDTV. Since that time an estimated two to three million receivers for HD have been purchased in Japan.
Image counts for a lot in Europe as well. Its pioneering work in the transmitting of HDTV began in 2004 and started off with Euro 1080-HD1 (its flagship channel). Since last year, HD2/HD5 has been added. HDTV is only beginning to gain headway in the European countries. The channels that broadcast HDTV in Europe are all available only with a subscription and no plans are in the works to alter this any time soon. It will only be a matter of time before television viewers in Europe have access to a variety of FTA HD channels. Plans are pending for this development.
The concept for the development of HDTV derived from movies viewed on a wide-screen. Movie producers gleaned from moviegoers that a movie screen that covered a larger width of space and took into account peripheral vision would improve upon the entire movie going experience. The image it portrayed was that bigger was, in this case, indeed better.
A wide-screen at a movie theatre could also be developed in the home entertainment field. This began to take shape in the early 1980′s when movie producers were presented with a system of HDTV that both Sony and NHK had been working on since the 1970′s. The system that had been developed produced images that greatly resembled the specifics of 35 mm film. The system was referred to as NHK Hi-vision.
High-definition television allows a film watched on a television screen to remain at the width it would also be on a standard movie screen but all features are enhanced. Scenes of island paradises, thunder and lightning storms, car races, sporting events, fireworks displays and thrillers with suspenseful moments all came to life so much more than ever before with the creation of HDTV.
Media images of HDTV are becoming more and more prevalent and Sony is no longer the only store to carry a full line up of HDTV sets. You shouldn’t have to look too far in any given electronics store to find HDTV screens looking back at you! It is one of the fastest growing trends in the electronics industry today.
The advantages inherent in HDTV including the improvements in sound and picture quality are catching on more and more all of the time. The very first station in the United States to broadcast HDTV was WRAL-HD located in Raleigh, North Carolina. Since then many big cities throughout the U.S. have followed suit as HDTV stations are becoming not just the wave of the future but also the reality of the present. A nationwide mandate has been put out by the Federal Communications Commission (abbreviated to FCC) for all television stations to have it within their ability to be able to broadcast television in the digital format as early as the year 2007.
