Jvc 4k/8k

[Craig Ryan]

Bring on the 8k projector! The more options theater's have to choose from the better.

I've heard one rumor that this JVC camera is just borrowing the RGB striped sensor from the F35/Genesis (which has 4MP each of red, green, and blue filtered photosites, 12MP total, one 2MP set per color for normal response and a second 2MP set for bright highlight information) and rather than using its secondary rows of stripes for improved highlight information to create 1080P with better dynamic range, they are using the secondary row to help create the 4K image, I guess somehow boosting the luminence of the darkened row to match that of the normal row. So rather than combining and downsampling this info to 1080P RGB with better dynamic range, it's converting it to 4K with less dynamic range.

This is also why it is a live 60P image, since the F35 can handle 60P.

I also think it's perhaps naturally "3.8K 4:2:2" due to the number of HD-SDI outputs its running to the projector, but I could be wrong in that.

Any news on Reds live output/real-time? This function @ least for 1080P 60P would be the clincher for broadcasters, if Red were to do it.

 

[Cory Schulthies]

here is my question, couldnt Epic do the same thing (output 4k in realtime) if red added a module designed to do that to the camera. And I bet the camera and module would be less that $200K.

Not as good as red, but still i welcome more players into the 4k+ space. Competition pushes technological advances.

I wonder what Jim would have to say about these developments. But i bet JVC is the furthest thing from his mind right now.

 

[David Mullen ASC]

I don't see much need for 4K RGB live monitoring with full quality debayering. It's such a niche application. 1080P would be fine in most cases for live outputting.

I seem to recall that Jim said they could put an uncompressed data output on their cameras but they'd charge something insanely high to do that, like making it a $100,000 option. In other words, don't ask.

But maybe they'll change their minds. However, I see the usefulness of an uncompressed RAW output not really for the purposes of generating a live 4K image.

I guess engadget got their “panties in a twist” in pure excitement and the announcement should have been more like this; http://www.electronista.com/articles/09/05/12/jvc.8k.projector.4k.cam/


JVC have been "blasting their horns" about this camera and 4K & 8/4K projector every 6 months for some years.

Till now I never seen a report on the performance of the 4K projector nor if it really is possible to buy yet.
Can it project movies as good as the Sony 4K? Which has not impressed the "high end HT boys". The 2K JVC HT projector has its fanboys, but is not deemed good enough for high end due to uneven light uniformity.

The camera is due "next year", which they said last year too.

Like mr. Mullen explained, the 8K projector is "8K ish";

The prototype projector is mounted with four microdisplays, which are three 3,840 × 2,160 pixel microdisplays and one 8,192 × 4,320 pixel microdisplay, developed by JVC as display devices.

To display an image, a full-color image is made by using the three 3,840 × 2,160 pixel display devices, and an 8,192 × 4,320 pixel monochrome image is made based on the luminance component of input signals. Then, those two images are combined to produce an image. The contrast ratio of 1.1 million to one is the product of the contrast ratios of the two images.

The good thing with these 4K announcements; like Sony and Warner announcing that all their new movies will be released in 4K and the $315mill deal Sony struck with AMC Entertainment theaters group is that it will hopefully force Texas Instruments to reveal what their plans are for 4K DLP rather sooner than later.

By the way, when we are about projectors;

And yet I still cannot find a single low serial number USED Red One Body for sale at a reasonable premium over original retail price.

This JVC 8K projector is in fact a new version of the one they promoted last year.

Primary features

1. The projector is fully compatible with the Super Hi-Vision standard (7,680 x 4,320) being promoted by NHK.
Conventional Super Hi-Vision projectors render images with 4,000 TV lines using an 8.29-megapixel (3,840 x 2,160) single display device and leveraging adaptive pixel correlation technique to adjust the RGB green component; this means that the red and blue components are not fully covered.

The new projector, however, uses a 35-megapixel (8,192 x 4,320) D-ILA single display panel that provides full coverage of each RGB component to 4,000TV lines.

2. The new projector generates a high light output of 10,000 lumens - or one-and-a-half times greater than two conventional DLA-SH4K models - and provides sufficient brightness fordisplays as wide as 400 to 600 inches, each pixel approximately 1 sq. mm in size.

Development Background
In 1996, JVC embarked on the development of Ultra High Definition image systems as the successor to High-Vision Definition.

The company developed the first 7.86-megapixel (3,840 X 2,048 pixels) 4K2K D-ILA device in fall 2000 and began supplying projectors containing this device for research applications in March 2001. In June 2007, JVC developed a 1.27-inch 4K2K D-ILA device having a 6.8μm pixel pitch and resolution of 4,096 x 2,400 pixels, and in February 2008 it began marketing a newly commercialized professional D-ILA projector - the DLA-SH4K - incorporating that device.
JVC has also been contributing to research and development of Ultra High Definition image systems at home and abroad by cooperating in the standardization of Digital Cinema Initiative (DCI) 4K2K specifications and by providing projectors for the Super Hi-Vision 8K4K system currently being developed by NHK.
Although the use of Full HD continues to spread among households worldwide, research and development into new television broadcasting standards that go beyond HD is gathering steam, and significant efforts are being made to satisfy growing demand for next-generation highdefinition imaging solutions for applications ranging from digital cinema and presentations to monitoring/control and health care.

JVC's new full-coverage, high-resolution Super Hi-Vision D-ILA Projector satisfies this growing demand for ultra-high-definition imaging by providing the world's highest resolution. In addition to the contribution that the projector will make to the advance of Japan’s broadcast television industry, JVC is certain that this new product can also contribute to the commercialization of Super Hi-Vision.
