Mitsubishi Demonstrates 4K2K Upscaling Tech

[exfileme]

On Tuesday Mitsubishi revealed its 4K2K upscaling technology to the press, closing the bridge between HD and the higher resolution.

Just a bunch of marketing BS, even the best algorithms cant "create" detail that is not there in the original. In the upscaling world, there is variations of spline, lanczos and a few exotic neural network algorithms (NEEDI2) that do very good interpolation.

With a ratio of 4.2667:1 the interpolation will not be super straight forward between current Full HD and this new Extreme HD. For video there had better be some serious hardware acceleration applied to this upconverting, I'm thinking CUDA or OpenCL with Nvidia or ATI hardware, maybe Toshiba's Spurs engine?

no, they can't add extra pixels. But, there is some very good hardware that is able to upgrade a signal to make it look better. Just like there are some TVs and receivers that can upgrade regular def TV to a 1080P signal and look good. It's not ever going to look as good as a proper resolution signal, but better than no algorithm at all.

If you could make an algorithm that works like a human brain, you could upscale without problems. If you take a frame, upscale it raw and then fix it manually, you can near perfection. Software just needs to get up to AI level in order to do this as it's more a decision process.

@mac_angel: thats my point, their marketing team is trying to create the illusion that they have invented some new super algorithm. This is not the case, and its EXTREMELY likely that its just a variation of spline or lanczos algorithm.

@climber: No need for cuda or opencl, they have a custom hardware chip that does the upscaling. Cheaper, easier, and uses less power.

@eyemaster thats what "neural network"s try to accomplish 😉

upscaling, pffft...

It has an HDMI port... no I just need a video card that can handle that resolution.

 

[nukem950]

I honestly want to know why they can not upscale it. I will be very upset if it is due to the DRM junk in it.
Please someone who knows why, please comment.

I am allso interested in why BD-content can not be upscaled?
With really big white screen it could be usefull before real 4K2K.

At 4K resolution, would even GF100 in quad-SLI be enough to run Crysis at max details with 16xAA/AF?

They really don't need an algorithm to upscale, they just need to partner with Rockwell and use a Retro Encabulator:

no because i bet crysis does not even support that resolution 😛 😛 😛

 

[coldmast]

will it also up-convert a 60Hz video signal to 480Hz

Silly willy, it's the HD5890 quad-crossfire.

[citation][nom]Rab1d-BDGR[/nom]Clearly they need to implement the algorithm used by the police and the CIA/FBI in bad movies: "Zoom in on that pixel... Digitally enhance. Look! In the reflection, apply a filter... Okay zoom in again on that licence-plate - enhance.... I can see a reflection of a face there - it must be the killer! Hey, I know that face..."[/citation]

Sadly, this is so true that it makes my head hurt. This the main reason i hate shows like CSI

Isn't this higher defined than some peoples own eyesight?

"Some" people - very broad statement. So people like Ray Charles?

 

[WyomingKnott]

That's a strange aspect ratio. Why on earth did they pick it? Does it match anything currently in use?

I like big TVs, but how big must your TV be to really notice the higher resolution. 1080p is still enogh for big screens. isnt it? perhaps 4k2k is nice for a privat home cinema. ok. but for an plasma or lcd screen?! hmm..
Does more pixels mean more energie also?!

I wrote a an article about this post in german..
