JAPAN NEWS: JVC develops Super Hi-Vision projector chip – 17x Full HD resolution!

Jvc 8K4K D-Ila It's just under a year since we brought you news of the work being done by Japanese broadcaster NHK to prepare for Super Hi-Vision TV, offering many times the resolution of current HD TV systems.

Now JVC has announced the development of its latest projector chip, offering more than 17 times the resolution of current Full HD systems, and forming the final link in the Super Hi-Vision broadcast/viewing chain.

The 1.75in 8K4K D-ILA chip is claimed to be the world's first single display device able to handle Super Hi-Vision. It offers a resolution of 35 megapixels – 8192x4320 pixels, against 1920x1080 for current HD TV systems – meaning the 7680x4320-pixel resolution of Super Hi-Vision is well within its capabilities.

As well as being used for Super Hi-Vision, JVC says the chip will play a part in the development of what the company calls "the ultimate in imaging technology: ultra-realistic 3D displays."

And this amazing picture quality is going to need a sound system to match. NHK is currently considering 22.2-channel capability.

If full hd needs at least a 40" screen to notice a difference. So in theory you would need a 640" screen for super HV ( 40x16) ?

Yup, something like that. NHK has been showing demonstrations on a 10mx5m screen, which would suggest a diagonal of about 11.2m, or 441in.

Let's face it, 26in Super Hi-Vision sets are going to be a bit thin on the ground.

I suppose cinemas could invest in these then!Just out of curiosity what resolution do cinmas use? and does this mean that 1920 x 1080 is not full hd compared to this or is it just relative to the current full hd?

The current digital cinema standard is 4K2K, as mentioned in the article.

And yes Full HD is only Full HD until fuller HD comes along. In other words, Full HD is just a marketing term, not any kind of standard.

I don't get this super hi-vision, going by your graphic all you need is 16 hd tv's arranged as super hi to get the same result, i though you achieved better images by getting more lines on a screen not by the size of the viewing area, or i'm i missing something?

There are more lines - four times more pixels on each axis

Sorry andrew i missed that bit.what is the maximum resolution you could go to or at what point can you not notice a difference the human eye can only see so much or does it turn into something else completely,will it go as far as holograms or similar?and what is the point of developing something hardly noone can afford or use?

I guess resolution is only limted by the size of picture elements that can be crammed onto an image sensor chip, and the pitch - ie the spacing between them.

So I guess we'll see resolutions continually increasing over time - after all, who would have guessed a few years back when we all had 640x480 resolution digital cameras - ie 0.3megapixels - that it wouldn't be long before we had easily affordable models offering 10megapixels or more?
