NHK and JVC develop 120fps Super Hi-Vision projector

Posted on 18/05/2012 by James Trew

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

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.
