ITU approves as standard after no broadcaster opposition
The International Telecommunication Union (ITU) has approved Japanese broadcaster NHK's Super Hi-Vision system as the standard for 8K video. The format proposal was unopposed by other broadcasters during a consultation period, which allowed the ITU to send letters to its members late last week, confirming it as the adopted standard.
145-inch flicker free 8K TV developed in Japan
Panasonic and Japanese broadcaster NHK have worked together on a 145-inch plasma TV with a native resolution of 7680x4320. The 8K display, referred to as "Super Hi-Vision" in Japan, is a marked increase in size compared to another NHK collaboration of 85 inches.
NHK 33MP sensor shoots 8K at high speed
Japanese broadcaster NHK's Science and Technology Laboratories group has developed what should be the most advanced video camera sensor in the world. The 33-megapixel sensor captures NHK's 8K Super Hi Vision video, at 7680x4320, but can do it at a very fast 120 frames per second. The speed, which is four times faster than needed for regular TV, would help preserve the extreme detail even in fast action scenes.
Sharp makes 85-inch LCD with 8k image support
Sharp has teamed up with Japanese broadcaster NHK on a prototype 85-inch LCD set that is the first to support a native 7680x4320 resolution. The much denser image lets it receive NHK's recently tested Super Hi-Vision broadcasts without losing any detail. Super Hi-Vision offers 16 times the resolution of 1080p HDTV, and NHK plans on sending out trial broadcasts in 2020.
NHK successfully test global 8k TV broadcast
Japanese broadcaster NHK has collaborated with NTT Electronics to successfully conduct an international test broadcast of Super Hi-Vision 8k resolution TV. As the technology uses a resolution four times higher than 1080p, it can be difficult to transmit the bandwidth without signal degradation. Along with the high-resolution imagery, the accompanying soundtrack can include up to 22.2 channels. NHK was able to successfully send the transmission from all the way around the globe (80,000km) with just a 0.3 second lag.
BBC, NHK send first SHV show from the UK to Japan
The BBC, in conjunction with Japanese public broadcaster NHK, have collaborated to not only film a live performance with a Super Hi-Vision camera at 7,680x4,320 (8K) resolution, but sent the live broadcast to Japan. The Charlatans performed for the first-of-its-kind broadcast, which is four times sharper than 1080p HDTV resolution. Super Hi-Vision technology was developed by NHK.
NHK intros SHV Ultra-HD
At the CommunicAsia technology expo today, Japanese national TV broadcaster NHK showed a projection system capable of 77680x4320 resolution, otherwise known as Super Hi-Vision (SHV) and exactly four times higher than 1920x1080 (Full HD) resolution. In contrast, 16 HDTVs at Full HD resolution would have to be stacked together to create one image equivalent to the Super Hi-Vision technology developed by NHK.
82-inch Samsung UDTV
Korean electronics giant Samsung is using the 2008 SID symposium in Los Angeles to demonstrate a new LCD TV, formatted to an original resolution standard. While commercial LCD panels are currently limited to HD resolution (up to 1080p, or 1900x1080), the Samsung set is claimed to operate at "ultra-definition," with a maximum resolution of 3840x2160. This is however below the forthcoming 4K standard (4096x1716), and not to be confused with the experimental ultra-high definition resolution (7680x4320).
NHK shows Braille display
Friday reports have the Japan Broadcasting Corporation (NHK) coming out with a prototype of a haptic display with a touch panel function that would allow the visually impaired to control a device or browse the Internet using Braille. Unlike haptic interfaces in mobile devices, which simply mimic the feel of pressing a button with a vibration or other tactile method, the display would produce a series of protrusions and recesses formed by small pins integrated into the display.
