BBC shows off 33-megapixel Super Hi-Vision Olympic footage, we ask: why?
The first live Super Hi-Vision broadcast for public consumption was of the Olympic opening ceremony in London last week. We didn't get to see that premiere, or the second or third screenings either -- but the fourth? Oh yes. We grabbed a seat right up front of a small theater inside BBC Broadcasting House, watched a live 33-megapixel feed from the Aquatics Center and absorbed some very fond memories in the process. At the same time, a question hung over the footage like a watermark: why bother? The world is barely getting to grips with the notion of 4K, which already solves pixelation at regular viewing distances, so why did the BBC and Japanese broadcaster NHK go to the expense of sending a dedicated SHV video truck, a SHV audio truck rigged for 22.2 channel sound, and the world's only three 8K Ultra HDTV cameras to London? Fortunately, we caught up with someone in charge who was able to respond to that question. Read on for what they said, plus a slightly fuller sense of what the footage was like to watch.
UK 2012 Olympics Super Hi-Vision tickets are available, grab a seat for some Ultra HDTV
If you're a UK resident, missed out a ticket to the London 2012 Olympics and find the extensive home and mobile coverage to be lacking in pixels have no fear -- free tickets are available for Super Hi-Vision screenings at three locations. While certain days and times are already fully booked, you can still get one of the first public glimpses of NHK's 8K Ultra HDTV technology at the BBC Radio Theatre, BBC Scotland (Glasgow) and the National Media Museum in Bradford (other viewing locations are in Japan and Washington D.C.) Before the games get started, the Radio Theater is screening a London Prepares promo from July 23rd to the 28th. During the games (July 28th - August 12th) all will have highlights of the previous day's action from the Aquatic Centre, Olympic Stadium, Velodrome, and Basketball Arena plus clips of the Opening Ceremony. The lone live feed is scheduled for Sunday July 29th, from the Aquatics Centre. Sure, you could be paying a fortune for scalped passes to be in the house when Usain Bolt, Ryan Lochte or Michael Phelps are doing their thing, or you could be enjoying 33MP video and 22.2 channel surround sound in one of the custom setups TechRadar previewed in March. Your choice.
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.
NHK working on Hybridcast interactive TV platform (video)
NHK is working on Hybridcast (an entirely different system to the Hybridcast 3D-delivery setup it demonstrated last year), a system that uses the internet to make vanilla TV broadcasts interactive. It works by pushing HTML5 overlays to your tablet and TV, so you can play along with quiz shows or follow a travelogue from the comfort of your couch. The company is planning to build a set-top-box with the technology ready for sale next year, with integrated TVs hoped to arrive from Sony, Toshiba, Panasonic, Sharp and Mitsubishi shortly afterward. You can see what the residents of Japan can expect by watching the video after the break.
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.
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.
Toyota breaks compressed air speed record, hits 80.3MPH with Ku:Rin
Thankfully styled like the more dashing cousin in the typically awkward-looking compressed air car family, Toyota's Ku:Rin (meaning Air-Wheel) has smashed the speed record for cars powered by (not necessarily hot) air. Sure, measuring a svelte 0.8m across, there's certainly no space for the kids or the groceries, but it can reach a maximum speed of 80.3MPH. All that driving force is generated from compressed air which acts as the fuel, expanding and powering the single motor. Don't expect air compressors to replace those petrol pumps just yet -- the range for this streamlined beauty is a meager two miles. Take a look at NHK's report in More Coverage for redefining of "blown away."
NHK's automated, animated sign language translator adds gestures to subtitles (video)
We've seen quite a few devices designed to help hearing impaired users communicate via phone or computer, but Japan's NHK Science & Technology Research Laboratories has just announced a new animated translation system to help get important news to deaf viewers . While televised subtitles may work for those who understand the language, people who were born deaf and learned sign language from an early age can have significantly more difficulty. NHK's system, unveiled at Technology Open House 2011, bypasses this problem by automatically comparing Japanese text to sign language, converting equivalent words into animated onscreen gestures, and replacing differing words with appropriate synonyms. There are, however, a few kinks to work out. While comprehensible, the translations aren't exactly fluent and researchers have been forced to manually adjust some awkward transitions between words. The ultimate goal is to create a system that could be used during emergencies or natural disasters, allowing deaf citizens to receive urgent broadcasts as instantly as their hearing compatriots. You can see it in action, after the break.
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.
NHK demos Hybridcast streaming, teams up internet and cable TV for superior 3D delivery
With all the hubbub surrounding competing 3DTV technology, it's easy to forget the all important delivery process: how is your TV getting its content, and what does it mean for the viewer? It may seem trivial, but the answer is all-too important to the folks at NHK, who are hoping to facilitate Full HD delivery for 3D content using a new hybrid broadcast system. Think you already have Full HD 3D? Think again: most broadcast 3D content is delivered via side by side transmission, forcing two images (one for each eye) into a single 1080p frame. This allows 3D content to pipe through existing HD channels, but when the separate images are reconstituted and upscaled, resolution and picture quality suffer. NHK hopes to resolve this by fusing broadcast transmission with broadband streaming, what it calls Hybridcast. In a recent dual-stream demo, NHK sent the image for one eye over standard HD TV broadcast pipes, and the other through those wondrous internet tubes, eventually reassembling the two streams into a single, Full HD image, ready for your hungry eyeballs. This prototype delivery system is little more than a demo right now, but with any luck, it'll be giving us a whole new reason to freak out about broadband bandwidth caps in the near future.
NHK's flexible OLED is both literally and figuratively green (video)
When it's not pushing Super Hi-Vision, the hopeful 7,680 x 4,320 successor to HD, NHK also dabbles in small, flexible OLED panels. The Japanese public broadcaster recently showed off a 5-inch prototype display that, while bearing a heavy green tint and very noticeable rows of dead pixels, was still a significant improvement over a similar screen it demoed in 2009. Sure, it's not quite as flexible or vibrant as Sony's rollable OLED from last year, but it does seem to suffer from fewer bad pixels -- an important step towards maturation. Don't miss the video after the break which offers some pretty nifty glimpses at a number of bendable OLEDs. It's clear the tech is still a little wet behind the ears, but we're definitely getting closer to a future populated with TVs that roll up for storage and e-readers that fold like a paperback.
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.
NHK shows off new wireless HDTV broadcast camera
Taking time off of its always-impressive Super Hi-Vision program, Japan's NHK took the wraps off its latest development, a wireless broadcast camera capable of less than 33ms delay per frame. Apparently current tech has about a .5 second lag time, but this one updates microwave tech to millimeter waveband, letting it switch between wired and wireless cameramen with no interruption. The cameras already got put to use in the 59th NHK Kohaku Utagassen music show, don't be surprised to see a lot more freely moving camera jockeys at live broadcasts in the U.S. very soon.
