Japan introduces 4000 scan-line TV
Tokyo, , May. 25 -- Japan's semi-government broadcasting corporation, NHK, demonstrated the world's first ultrahigh-definition 4,000 scanning line video system Monday.
The system, which supports 16 times more information than existing high-definition broadcasting systems, would present wide-scope, very large and realistic images, the Fuji Sankei Web reported Tuesday. The demonstration took place at NHK's Science and Technical Research Laboratories in Tokyo.
The screen, 5.6 meters wide and 9.8 meters tall, corresponds to a 450-inch screen, compared to popular TV screen sizes of 20-40 inches. It conveys "a much stronger sensation of reality to viewers, a sensation of being at the site of, or actually in, the broadcast," according to NHK.
The number of scan lines determines the quality of screen images. The new system uses 4,320 lines, compared to the 1,250 lines used in high-definition systems.
