See more of the benefits of HDTV

So far, we are already familiar with the system of national television system committee (NTSC) which is used television to present the image. However, lately with the advent of technology, high-definition television (HDTV) causing the function of the NTSC. What exactly is this HDTV technology?
The rapid advancement of digital technology, especially in the field of digital images that combine photos and video, it's not unprecedented. The presence of HDTV technology, not just pushing products with quality in some brands of digital television devices that already have a name, but also on how the recording for broadcast in HDTV.

Until now still difficult to define exactly HDTV. To be sure, technology is considered the best television shows today are using the NTSC system (National Television Systems Committee) which delivers the analog picture, yielding a resolution of 525 lines on a television screen. While the 1125 line resolution HDTV produces a more solid impression and can produce video information five times more than the NTSC system.
However, despite having an incredible advantage in producing a conference resolution, sharp, and clear, the transmission bandwidth that HDTV requires up to five times greater than the capacity of conventional television signals. Although still difficult to define, HDTV can be interpreted as a system of pictorial communication media and / or speak with a level of quality of image sharpness (resolution) is very high (almost equal to the quality of 35mm film) and the sound quality is also like a CD (Compact Disk).

In this case the digital signal processing technology and the display provides a very important role. It is also hoped that later can serve multi-lingual and multi-media. Because HDTV is a communication system, as well as the other conventional communication systems, to operate requires several basic components such as the production center (studio), processor / storage, transmission and receiver systems.
The basic concept of HDTV on the other side is not really intended only to improve the definition of impressions per area unit of the television screen, but also to increase the percentage of visual field that shows the image. HDTV development is directed at the 100 percent increase in the number of pixels horizontally and vertically, for example, 1 MB of frame images should have a number of 1000 lines x 1000 horizontal points.

The result of this expansion is a factor of 2-3 times improvement in the field of vertical and horizontal angles. Thus, this angle repairs on the HDTV also changed the ratio to 16:9 from 4:3 and becoming like the displayed image in the "cinema". HDTV is a new communication media and technology are in the process of improvement, especially in the early decades of the 90s.
Brief history of HDTV development initiated by Japan that was driven by research and development center NHK (TVRI / her RRI Japan) in 1968. Then followed by the European community as a comparison the United States and eventually become a competitor to be reckoned with.
HDTV technology is estimated that this will be the future of television standards, so a senior researcher in the field of systems and management strategies Dr. Indu Singh predicts that the world market for HDTV would reach 250 billion dollars per year (year 2010).

Standard Competition
In addition to a lucrative market aspects, Up in the HDTV system has a wider impact on its cultural, social, political to the defense. Therefore, developed countries have been vying for the system they developed that can then be used as the standard of the world (global).
Standard which has been in the meeting agenda CCIR (international agency which handles standardization broadcasting system), only two are MUSE (Japan) and HD-MAC (Europe). Meanwhile, the United States are regulated by the FCC (Communications Commission) is being stressed to decide on one standard from each team (the consortium) who are competing.
Because the interests of each country's different CCIR can decide whether the use of a single standard? Experience of conventional TV system that is the PAL / SECAM in Europe & ASEAN, NTSC in the U.S. and Japan, it was hard to decide CCIR for single use this HDTV broadcasting system. In addition there is also under the ISO standardization bodies dealing with the standardization of MPEG encoding and compression of moving image signal.

Every country of course, wanted that his country can move forward in all respects, including HDTV technology. For developed countries that infrastructure already complete, the problem is the application of the competition. However, what about the infrastructure of developing countries is still limited (see above idealization broadcast system), whether to create their own standards or follow the standards being developed by the developed nations. apankah HDTV is feasible?
Because the existing level of HDTV technology is so advanced, the possibility of creating a standard signal itself is only wasting time and money. Wise if the developing countries can learn this system in terms of HDTV production, transmission, receivers and even the manufacture of these components. Because without being able to produce, proficiency level in these countries will always depend.
For example integration done in Japan for the development of the television industry that began decades 50s. With driven by Research and Development Center for NHK, the Japanese forced domestic industries (Sony, Matsuhita, etc.) to be able to produce television and related components with orientation beginning of the domestic market.

With a broadcast carried live on television the wedding ceremony the emperor (emperor) Akihito in 1959, burst into the television industry in Japan. Finally, as we know full well that the Japanese have been able to dominate television technology and world markets. Even has successfully broadcast HDTV programs 8 hours a day (from 25 November 1991).
Another example is South Korea. They are not in a hurry entered operate at a standard not yet established. But they are pursuing is how to produce HDTV to be exported, so they send out experts who can make the HDTV to
Japan, Europe and America. This activity is a consortium of government and related industries such as Golden Star, Samsung, Daewo, and Korean Telecom. HDTV production development project in Korea was started in 1989, at a cost of 100 billion won, 60 percent of them expelled from the pocket of government.

Implementation of HDTV Terms
To be able to conduct HDTV broadcasting system, both nationally and globally that ideal, it may take several criteria including the following:
1. Use the same standard signal (in the world / in one state).
2. Low cost receiver / bought by the public.
3. Compatible with existing systems.
4. Can be linked with other media (multi-media).
5. Can be widely affordable (redistribution).
