It has four times more resolution than the Ultra High Definition content; each frame of video is a 33 megapixel image; They seek to promote their use for the Olympic Games in Japan in 2020
The chain of Japanese state broadcaster NHK began today its emissions test ultra high definition 4K and 8K, aiming to refine this technology and generalize their use before the Olympic Games the Japanese capital will host in 2020.
This is the first issue of global trial held in 8K, the superior format within the so-called ultra high definition has a resolution of 7680 x 4320 pixels (33.2 megapixels), ie sixteen times more than the current HD standard.
in 2014 they had done a pilot with a single transmission. In September last year went on sale the first TV 8K, the Sharp VL-85001.
The emissions will be implemented in the satellite of NHK channels, and it is expected that by 2018 the format of ultra high definition is usual in them, state chain Japanese
the technology of ultra high definition or 4K quadruples the number of pixels in a screen Full HD, so that the resolution is four times higher than high definition currently used. Full HD has pictures of 2 megapixel (1920 x 1080), while in 4K are 8.2 megapixel (3840 x 2160 pixels). 8K images are four times more color points, with 33.2 megapixels per frame (7680 by 4320 pixels).
However, viewers will not capture 4K and 8K broadcasts with receivers and conventional TVs, so NHK plans to install such devices in their offices and in public places in major cities across the country to promote the new technology.
the 8K format had been used in phase evidence in other countries, although Japan was one of the pioneers in its development thanks to projects carried out by NHK in collaboration with Japanese universities and companies such as Sony, Panasonic, Sharp and Toshiba.
