ITU approves NHK's Super Hi-Vision as 8K standard, sets the UHDTV ball rolling very slowly
We'd heard that the International Telecommunication Union was close to approving Super Hi-Vision as an Ultra High Definition TV standard, and the UN agency hasn't waited long to confirm the rumors. The recommendation to use NHK's 7,680 x 4,320 format has gone unopposed and should define the parameters for incredibly detailed 8K video worldwide. This shouldn't lead anyone to return that 4K TV just yet -- once again, it's important to remember that NHK still won't start any kind of wider testing until 2020. That's also assuming that the first 8K sets are down to Earth instead of the incredibly expensive 145-inch variety.
Nikkei: ITU near recommending NHK's Super Hi-Vision as official TV standard
We've seen NHK preparing its Super Hi-Vision 8K video since time immemorial. Wouldn't it be nice if the TV broadcast technology was more than just a perpetual research project? If sources for Japan's Nikkei aren't dreaming, the International Telecommunication Union is now "likely" to declare the format an official standard for broadcasters and TV makers. Should it go ahead, the UN telecom body would ask the world to rely on Super Hi-Vision as an eventual successor to HDTV and reduce the balkanization of TV standards that we've seen in the past. Neither the ITU nor NHK is known to have commented on the claim so far, but NHK isn't exactly in a rush to get a seal of approval from anyone -- widescale test broadcasts aren't coming until 2020, and production TVs themselves are only just entering a 4K universe.
NHK lays out Olympic broadcast plans, Super Hi-Vision test viewing locations in Japan
We've already run down Olympic broadcast plans in the US and UK, and now Japanese broadcaster NHK has unveiled some information. Similar to the others there is not only the TV production including data about ongoing competition, but also an online component complete with live video access on mobile devices, but also support for the acTVila video on-demand portal. The other notable information is that it's locked down locations and details for those trial Super Hi-Vision broadcasts, listing four spots where people can get their eyes on some sweet 8K UHDTV action. While most of them will be displayed by projectors, including a 520-inch screen in Shibuya, while Akihabara's Studio Park will feature a 360-inch LCD. The details for UK and US are a bit more vague, but if we have to track where in Washington D.C. NBC is letting the 33MP resolution video and 22.2ch sound out for a trial just by its scent, then that's what we'll have to do.
ITU lays out recommendations on 3DTV, Ultra High Definition TV standards (video)
The ITU has stayed busy, as we mentioned earlier it met to hammer out standards for UHDTV (Ultra High Definition TV), and also recently announced a new set of recommendations for 3DTV. On the 3D front it focused on standardization for delivering video in both 720 and 1080 line formats, digital interfaces used for studio production and methods to evaluate quality based on picture quality, depth and comfort levels. As far as UHDTV which is still quite a bit further off, the group has decided the term will cover both 4K and 8K (aka Super Hi-Vision) resolution video, as multiples of the existing 1080p standard. That means Quad Full HD (QFHD, or 3840x2160 resolution) and Digital Cinema 4K resolution (4096x2160) both fall under the umbrella of 4K (check the aspect ratios to see where the "missing" pixels went, or have a listen to this week's podcast. After the break we've got a video with Study Group Chairman Christoph Dosch discussing the future possibilities of both 3DTV and UHDTV, as well as press releases with a few extra details.
Ultra HDTV technical standards agreed on, more pixels is a good thing
The high-definition pride of your living room may not want to hear it, but it looks like ultra high-definition TV (or UHDTV) has now taken another step towards reality. While shop-floor products remain years away, experts in the ITU Study Group on Broadcasting Service have made several agreements on technical standards for your (next?) next TV purchase. Increasing pixel count in future sets is also expected to improve viewing angles on glasses-free 3D, which needs more dots to work its lenticular magic. 33 megapixels sounds like it should be enough to work with.
