INTRODUCTION [1]
With their advanced technology allows HDTV
flexible and efficient than analog systems used in current television program but designed computer cannot continue to replace the TV in the near future. While viewing the list through a computer. May be used to see a small one on the screen butin reality. Consumers Want more than the demands of various and multiple personality. Coupled with advanced communications technology, fast and lower costs. It allows visitors to design their own television program. Although the development of television seems to be no obvious change anything. Until the switch to digital television systems, digital television (Digital Television/ DTV) is a new technology of television with the digital signal. High-performance all-definition television image and sound today. Using analog technology (Analog), but primarily the new DTV technology. The same Computer. Is a digital television signal in the current Analog System or linear in the transmission - signal that computer systems are more developed. Adoption is in the development of television signal. [2] The take a combination of both technologies is the digital television.signal.
[2] The work of the HDTV a digital signal sent to the TV through a digital signal data compression by MPEG-2 decoder to then be transmitted to the lamp beam shooting out a TV screen came to cause Pixel (the image on screen but In HDTV systems will provide a higher Pixel TV very general picture quite make out the detailed definition. Symptoms that no flash pictures of signs. [4] How HDTV works HDTV constitutes a tremendous leap forward in image quality by providing up to five times higher Resolution than standard analog TV. This means sharper images, better color fidelity and a wide Screen format, i.e. 16:9 Radios.

Contemporary systems. In addition to an HD Ready television, other equipment is often needed for the home user to view High Definition Television. There are several sources of high definition content and the equipment used to control each of these must be HD compatible.High Definition picture sources include terrestrial broadcast, direct broadcast satellite, digital cable, high definition discs (Blu-ray and HD DVD), internet downloads and the latest generation of games consoles.The availability of television pictures broadcast in the HD format varies by region and country.
[7] Much has been said about
HDTV but little has been published for the visual aid for those unfamiliar with the actual types of graphics available to TV and computer screens. High definition TV has two formats, 720p and 1080iThese terms are explained in the graphic which can be clicked on to enlarge.720p has over two times the resolution of current standard resolution TV's.1080i has five times the resolution of current standard resolution TV's. The extra lines gives a far more detailed and clearer picture. Please see the graphic and using the legend below this may help to explain the differences. [8]
