NHK Projector Features Insane 7680 x 4320 (8K) Resolution

Sean Fallon — Fri, 20 Jun 2008 15:55:00 EDT

Japanese TV broadcaster NHK has demonstrated Super Hi-Vision, their whopping 32 megapixel, 8K (7680 x 4320) ultra-high definition projector technology using two LCoS projectors with a combined 8,000 lumens brightness and a towering 6.6m x 3.7m 300-inch projection screen. For those of you who are counting, that absolutely obliterates the 4K (3840 x 2,160) full-HD standard. They have even developed a matching 8K studio camera. Once again this raises the question: is there such a thing as too much HD? [CNET]

Super Hi-Vision Gets 33-Megapixel Sensor for Full-Color Video

Remember NHK's Super Hi-Vision, the 7680x4320 format that looks so good viewers throw up? The research group finally prototyped up a 33-megapixel video sensor that could take in the whole picture at once.

Before, according to IDG, they were using four 8.3 megapixel sensors—two for green and one each for red and blue. But that data only yielded only a black-and-white image at full resolution. Now they can shoot in full color and reproduce the picture in color too.

Needless to say, a special lens was required, as was a new cable system: instead of 16 separate coax cables, they've narrowed it down to a "single" 12-core line. One step closer to that TV wall in Total Recall, baby. [IDG]

Next-Gen HDTV is So Clear It'll Make You Throw Up; I See No Problems With This

You may recall that last May I told you about Super Hi-Vision, the next-generation in high def that promises an insane resolution of 7680x4320, or 16 times the resolution of HDTV. It turns out that it much be a little too high-def; it's so realistic it might just make you sick.

Yes, fast moving images at that resolution will probably cause motion sickness according to the eggheads at Japan's NHK who are developing the technology. Adding to the practical issues the format will face is that there's no real way to cram that many lines of resolution into a display any smaller than 60 inches, and even if you could cram them into a smaller screen there'd be no point to it. You wouldn't be able to tell the difference anyways at that point.

Despite the fact that the format isn't expected to be broadcast until 2025, NHK has built what's probably the sweetest home theatre setup in the world to play around with it: a 500 inch Super Hi-Vision screen hooked up to the world's only 22.2 multi-channel surround sound system. Take that, Panasonic. [BBC]

Super Hi-Vision Makes Your HDTV Obsolete Already

Adam Frucci — Tue, 29 May 2007 09:26:51 EDT

You think your HDTV is impressive? Your HDTV sucks. Sorry, I don't mean to be a jerk, but it's no longer cutting edge. 1920x1080? Please. Japanese broadcaster NHK has come up with what they call Super Hi-Vision, and it puts HD to shame with an insane resolution of 7680x4320. Yeah, that's the equivalent of 16 HDTVs crammed into one. Like I said, your HDTV sucks.

That's not all: The viewing distance can be four times as close as HDTV (.75 times the screen height versus 3 times the screen height for HDTV). Fortunately (or unfortunately, depending), you won't need to toss your HDTV for a SHV set anytime soon. That humungous resolution requires an insane 24Gbps stream for broadcast, which is nowhere near what we're currently capable of. Furthermore, they just developed the first sensor for cameras so they can actually, you know, shoot video at that resolution, but there's still a lot of work to be done. Seeing that NHK are the dudes who developed HDTV in 1969, it might be a while before these things start ending up in living rooms. –Adam Frucci

LG Sticking to "Full HD" at CES

Louis Ramirez — Tue, 02 Jan 2007 15:54:23 EST

Walk the floor of any tech trade show and chances are you'll be bombarded with booth babes and HDTVs. Not much can be done to improve the former, but LG is hoping it can do something about the latter so they've teamed up with Japanese broadcaster NHK and Sega in an effort to demo 1080p programming only throughout their booth at CES. Most of the content will come from NHK, who will provide LG with experimental 1080p broadcasts they've filmed using high-speed motion cameras. It'll be interesting to see what NHK can come up with and it'll definitely beat watching the same generic movie loop everyone else will be showing. – Louis Ramirez
