Tokyo, Aug. 1 (EFE) .- The Japanese chain NHK state television today began its emissions test ultra high definition 4K and 8K, with the aim of refine this technology and widespread 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 4,320 pixels (33.2 megapixels), ie sixteen times more than the current HD standard.
emissions will be held on NHK satellite channels and it is expected that by 2018 the format of ultra high definition is usual in them, reported the Japanese state broadcaster.
the technology of ultra high definition or 4K quadruples the number of pixels of a screen HD, so that the resolution is four times higher than HD or high definition currently used.
However, viewers will not capture emissions at 4K and 8K with receivers and conventional televisions, 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 4K format had already been used in testing 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.
two years ago, a channel Japanese testing, called Channel 4K and operated by the company NexTV-F offers free content in ultra high definition 4K produced by other stations in the group for six hours a day.
Japan’s state television plans to broadcast in 8K opening ceremony of the 2020 Tokyo Olympics and the swimming and athletics
