ITU meets to define 4K and 8K UHDTV parameters
This month NHK has been previewing a slew of Super Hi-Vision equipment, but there's still much work to be done to make high res broadcasts a reality worldwide. There's where the ITU steps in, and as it did for HDTV back in the 90s it's been meeting to decide just what 4K and 8K Ultra High Definition TV (UHDTV) broadcasts are and how they will work. There's no word on minimum pixel counts for the standards -- we expect that quad-HD vs. 4K battle to rage on, remember these are the people who "defined" 4G -- but they're establishing color range, frame rate, and whether the broadcasts will go over unused satellite bandwidth or regular antenna frequencies. If you're somehow confused by the 33MP video streams that are coming our way... some day, check out a video featuring European Broadcast Union Deputy Director of Technology and Development David Wood.
NHK and JVC develop 120fps Super Hi-Vision projector
If your cine-cave is already decked out with the Super Hi-Vision display, the Super Hi-Vision camera, and the Super Hi-Vision-supping antenna, we guess you just need the 120fps Super Hi-Vision projector to complete the set? Guess what? Working with JVC, NHK has developed just that. It might not be much to look at, but that hunk of tech up there comes with the extra frame rate that also makes it play fast nice with the sensor technology NHK was kind enough to develop first. The projector will be giving its first public demos on May 24th , and we hope that 7680 x 4320 resolution will make all those hi-res skate-slams come out a charm.
NHK makes first successful Super Hi-Vision OTA broadcast, man cave owners giggle with glee
Fresh off from successfully shrinking its Super Hi-Vision camera, Japan's NHK is sticking another feather in its cap -- the first over-the-air broadcast of its super-duper high-resolution technology. The broadcaster says it recently managed to send a compressed Super Hi-Vision signal from the roof of its Science and Technology Research Laboratories in Tokyo to a distance about 4.2 kilometers away with no issues. NHK used two UHF channels during the experiment. To optimize and boost transmission capacity, NHK leveraged technologies such as orthogonal frequency-division multiplexing (OFDM) and multiple-input multiple-output (MIMO). Low-density parity check coding was also used for error correction. NHK has been constantly experimenting with its Super Hi-Vision high-resolution (7,680 x 4,320) video format, including a UK-to-Japan broadcast via a 24Gb/s internet connection in 2010. Folks who happen to be in Japan from May 24th to 27th can check the tech at the NHK labs' open house in Tokyo's Setagaya ward.
NHK shrinks its 8K Super Hi-Vision-ready camcorder to the size of HD cameras
We may still be years away from watching the sweet, sweet 33MP resolution video promised by Super Hi-Vision in our own homes, but over in Japan, NHK engineers are slowly working out the various kinks keeping it from us. Their latest development is this camera seen above on the left, capable of recording 8K in a camera head that is smaller and lighter than the previous unit (the new one weighs 4kg, about 1/5th the weight) shown on the right, and is more comparable to the size of a standard HDTV camera. According to the NHK the savings were achieved by developing a new single plate color imaging mechanism and eliminating the need for a prism to separate the colors beforehand, so it's small enough to be used with standard SLR camera lenses. Sure, it's not quite ready to go on your next vacation, but if you're in Japan you can get a peek at it (and that 145-inch 8K Panasonic plasma) at the broadcaster's open house later this month.
Panasonic teams up with NHK on 145-inch 8K Super Hi-Vision plasma TV (Update: video)
We thought the 8K 85-inch Super Hi-Vision LCD we saw during CES was impressive, but Japanese broadcaster NHK is already looking to surpass that by going even bigger. To that end it worked with Panasonic (above: that's Panasonic's Keishi Kubota on the left, Yoshio Ito of NHK on the right) to create this 145-inch prototype plasma, unveiled today as an example of the kind of displays we can expect to see once broadcasts jump to the higher resolution some day. The world's first self-illuminating Super Hi-Vision TV, it features every pixel of its expected 8K resolution -- 7,680 x 4,320. After working for months on smaller (only 85- or 103-inch) 4K plasmas, the two companies had to come up with an entirely new drive method for the display that works by scanning the pixels vertically to achieve a uniform picture quality. The NHK plans to show off the new display at its open house in May, although we're a bit more interested to see if we can watch the Olympics on it this summer. Check the gallery below for a few more pictures from DigInfo.TV's Ryo Osuga, or hit the more coverage link for a breakdown of the difficulties encountered in building a high resolution display that's this massive.

NHK's new Super Hi-Vision sensor captures 8K at 120fps, fast enough for Usain Bolt?
As amazing as Super Hi-Vision televisions are, most of the footage we've seen is of slow-moving cityscapes, nature and portraits. We may get more action sequences soon, thanks to a new CMOS sensor capable of picking up 8K (33MP) footage at 120 frames per second. The joint project between NHK, Shizuoka University and the Research Institute of Electronics is being shown off on the 27th at the International Solid-State Circuits Conference The chip is developed on a .18 micrometer process, with an enhanced analog to digital converter that enables the faster frame rates. That cut down data processing time and power consumption, all key to getting some sweet super high res televisions (16x more pixels than your current HDTV) in our living room sooner rather than later. Our only question? If they can build a new camera around it in time to catch the world's fastest human being do his thing at the 2012 London Olympics.
CES 2012: HDTV and connected devices round-up
The Consumer Electronics Show is always a big deal for HDTVs and the devices that plug into them, and the 2012 edition was no different. With the majority of households already owning an HDTV, manufacturers are pressed to convince you to upgrade, and are pulling out all the stops. We've got new display technologies like OLED, 4K and Super Hi-Vision, plus more 3D and internet connected features than ever. DVRs and media streamers haven't slowed down either, so while some services focused on eliminating the set-top box, those that remained either shrunk (Roku) or added features (Boxee, TiVo, Ceton -- pictured above). The pace of the announcements made it nearly impossible to keep up with everything going on last week, so we've wrapped everything up in one neat summary available after the break.
Sharp 8K Super Hi-Vision LCD, 4K TV and Freestyle wireless LCD HDTV hands-on
We got a hint of Sharp's plans during its CES 2012 press conference two days ago, but really nothing can prepare you for the sight of the company's 7,680x4,320 resolution 85-inch Super Hi-Vision 8K LCD. No matter how close we got, we still couldn't see the pixels, and the video reels being demonstrated showed an almost unimaginable level of detail. The worst part of it was, seeing that first almost ruined the experience of checking out the ICC 4K demo at the other end of the booth. We can say this -- after seeing Super Hi-Vision there's really no going back. Make an appointment to see those 33MP broadcasts from the London Olympics now. Also a concept, but packed in a more conventional design, were Sharp's Aquos Freestyle LCDs. These featherweight flat-screens were also featured in the press conference, and pack wireless HD streaming inside capable of extending up to 98 feet. The 20-incher in the video above even has a battery good enough for two hours of completely wireless 1080p viewing. While Sharp called them concepts, the displays seemed incredibly polished, so check them out in the gallery below because you may see them on shelves someday.
2012 London Olympics Super Hi-Vision broadcast coming to select US, Japan, UK locations
While Super Hi-Vision isn't expected to bring its 7,680 x 4,320 resolution (16x more detail than your 1080p display, for those keeping count) home for several years, the NHK and BBC have confirmed it will be available for public screenings next year during the 2012 London Olympics. Screening dates have been arranged for three countries (Japan, UK, and US), and it appears domestic viewers will want to plan on visiting the Washington D.C. area next July / August to get a taste of the 33 megapixel video and 22.2 channel surround sound for themselves. Next year's Games have already put extensive 3D coverage on the schedule and NBC has promised every event will be available for viewing live as it happens for the first time, so there's plenty for everyone to look forward to. The only question now? Whether or not that silly false start rule can be changed so we don't face the prospect of a men's 100m dash final without Usain Bolt in it.
NHK develops ultra high-def camcorder with single 33 megapixel sensor (video)
As still cameras go, a 33MP sensor is rather insignificant, considering you may already be walking around with 200 megapixels on your shoulder. When it comes to camcorders, however, this is the real deal, especially when each and every one of those 33 million pixels is captured by a single, ultra high-def sensor. NHK's research arm, which developed the cam, unveiled it at the company's technology open house in Tokyo. This seems like the perfect imaging device to show off Sharp's 33MP Super Hi-Vision TV, but that display must have been on duty at another booth. Also, the Sigma DSLR lens was focused on a still life, without any mention of frame rate, so we're a bit skeptical as to whether this thing is fully functional at this point. Either way, it's still just a prototype, so you won't be shooting your home videos in quasi-IMAX resolution just yet. In the mean time, jump past the break for that motionless video demo.
Sharp shows off the world's first Super Hi-Vision 85-inch LCD with 16x more detail than 1080p
While Japan's NHK has been working on the successor to HDTV, Super Hi-Vision, for years, there haven't been any direct-view HDTVs capable of showing its full 7,680 x 4,320 pixel resolution until this prototype unveiled today by Sharp. Its 103 pixels per inch may be just a fraction of those found in some of the pocket displays we've seen at SID this week, but that's still far more than the 36ppi of a 60-inch 1080p HDTV. If estimates are correct, we'll still be waiting until around 2020 for that 33MP video and 22.2 channel sound to actually be broadcast, although there's a possibility of some demonstrations happening during the 2012 Olympics. Skip past the break for the available specs and a video demonstration, or just head over to the NHK's Science & Technology Research Laboratories in Tokyo between the 26th and 29th of this month.
First Super Hi-Vision broadcast from UK to Japan is one for the geeklopedia
Super Hi-Vision is still very experimental, but the BBC and NHK's first UK-to-Tokyo SHV broadcast trial of a live musical set by the The Charlatans hints it is inching closer to commercial viability. A NHK-developed camera -- one of three in existence -- made it all possible, and featured a specialized lens and optical data transmitter to handle the retina-confounding 7680 x 4320 pixel signal. This SHV trial was also the first to use a blazingly fast 24Gb/s internet connection to broadcast in lieu of more expensive satellite transmissions used in previous tests. As if the brouhaha wasn't bleeding-edge enough, a lucky few at the BBC could even view the show on a prototype 103-inch plasma television developed by NHK to see a mere quarter of the signal's massive resolution. Sure, this may not be the kind of event kids will learn about in class someday, but it certainly makes us feel like giddy little school boys. To learn more, watch a behind the scenes BBC video on the event embedded after the break. [Thanks, Matt]
NHK prototypes one-fourth of a 116-inch, 8K plasma set (video)
NHK has been working on 33 megapixel, 8K Super Hi-Vision displays for quite some time now. As the story goes, in 2005 the group's Science and Technology Labs estimated a necessary 0.3mm dot pitch for plasma screens in the 100-inch category to achieve the necessary 7,680 x 4,320 pixels for display. At the time, the best plasma could muster was 0.9mm, but now the researchers have created a prototype 58-inch screen with 0.33mm pixel pitch. Ergo, four such prototypes stacked together should create a 116-inch window to the world that just about displays 8K video. It's still a ways off from market, but be honest, are you really already griping about the visible pixels on your 1080p set? Totally inadequate web video version after the break.
Forget HDTV and 3D, when is Ultra HDTV / Super Hi-vision coming home?
Not willing to make predictions about the future of HDTV with all the other analysts, In-Stat has jumped ahead with its latest report, a peek at the future of Ultra High Definition (though the kids are calling it Super Hi-Vision these days.) We'd heard the 8K / 4K broadcasts could flip on as early as 2015, but this report pegs 2017 - 2022 as a more likely time period, with the expectation that 28.2% of European households will be sporting the 22.2-channel audio spec by 2025. Of course, if you must be first on the block with it, there's always JVC's $175k DLA-RS4000 available right now.
MPEG group working on AVC replacement for Ultra High Definition video of the future
The tech around Super Hi-Vision technology may not be completely worked out yet, but with that on the way, plus HD for mobile devices and even more streaming, the 88th meeting of the MPEG/ISO standards group in Maui was apparently a busy one as attendees voted to work on a new, better form of compression to replace MPEG-4 AVC. "High Performance Video Coding" (HVC) is just a dream at the moment, but be sure to pencil that in as one more spec to look out for in the future. Of course, they didn't mention a delivery system for 22.2 channel audio, but we'll just assume that's being handled as well.[Via EE Times UK]
Samsung SDI shows off 63-inch 4k x 2k plasma
There's a slight possibility that you haven't noticed, but Samsung SDI is on fire. Like, seriously burning down FPD International 2008. After treating onlookers to a flexible OLED, a 40-inch Full HD OLED display and an assortment of other eye-enticing panels, the outfit has one-upped itself once more with a 63-inch 4k x 2k plasma. Sure, actually finding 4k x 2k content will be a challenge, but who wouldn't want to be ready for the inevitable worldwide domination of Super Hi-Vision? Most of the other specs (contrast ratio, luminance, where it's being stored with loose security, etc.) were sadly absent, but with a native resolution like this, the rest takes a back seat anyway.
Super Hi-Vision demo seen in totally inadequate web video player
By now, you're completely familiar with what Super Hi-Vision is looking to do. You know, revolutionize HDTV programming as we know it. Provide an intense amount of detail good for filing up hundred-foot screens. That type stuff. If you've been eager to actually see what SHV can do, but you weren't able to make the trip to Amsterdam for IBC2008, fret not -- Auntie Beeb has hosted up a video of the demonstration in a wee web video player. Nah, it's no 7,680 x 4,320, but at least you'll get the idea. (Psst... it's in the read link.)
NHK demonstrates 8K display: 16x more detail than 1080p
Looks like NHK brought a prototype 33 megapixel, 8K Super Hi-Vision projection system to the auditoriums of CommunicASIA. Using a pair of LCoS projectors, NHK threw 7,680 x 4,320 pixels illuminated at 8,000 lumens onto a screen measuring 6.6 x 3.7 meters. The images were recorded from a prototype 8K studio camera -- as good as it gets until the first live SHV television broadcasts are demonstrated in September.
BBC teaming with NHK for Super Hi-Vision trials
Talk about getting around. Auntie Beeb has jumped from Freeview to FreeSat to Sky HD to iPlayer to who knows where else in no particular order, and while the vast majority of Europe is still struggling to adopt vanilla HD, the network is already dipping its toes in the next best thing. Reportedly, the BBC is all set to participate in a transmission trial using the Super Hi-Vision (SHV) system developed by Japan's NHK. The series of demonstrations will combine content from Japan and London, and the actual screenings are supposed to take place in the NHK Theater using an 8k x 4k projector. We'll admit, this isn't the very first time we've heard that The Beeb may be interested in this stuff, but with the UK-based 2012 Olympics growing ever closer, it looks like the dedication may be ratcheting up.[Via TechRadar, thank L. Rawlins]
Japan's NHK demonstrates 33MP image sensor prototype for SHV
Considering that we just doused you with acronyms in that headline, let us break it down real quick. Japanese public broadcaster Nippon Hoso Kyokai has recently demonstrated a prototype 33-megapixel image sensor -- which enables engineers "to use one chip per color" -- for its baffling Super Hi-Vision technology. With this device, each color sensor can operate in full resolution, whereas previous iterations relied on a foursome of 8.3-megapixel sensors (two green, one red, one blue) in order to reach 7,680 x 4,320 pixels. No worries if all these huge numbers are blowing your lid -- this stuff is still years away from being away close to mainstream.
