ITU lays out recommendations on 3DTV, Ultra High Definition TV standards (video)

Posted on 01/06/2012 by Richard Lawler

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.

ITU meets to define 4K and 8K UHDTV parameters

Posted on 24/05/2012 by Richard Lawler

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 makes first successful Super Hi-Vision OTA broadcast, man cave owners giggle with glee

Posted on 17/05/2012 by Jason Hidalgo

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

Posted on 11/05/2012 by Richard Lawler

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)

Posted on 27/04/2012 by Richard Lawler

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.

Update: Now with video from DigInfo.tv.
