Sources Say ITU Has Approved Ultra-High Definition TV Standard
Qedward writes with this excerpt from Techworld: "A new television format that has 16 times the resolution of current High Definition TV has been approved by an international standards body, Japanese sources said earlier today. UHDTV, or Ultra High Definition Television, allows for programming and broadcasts at resolutions of up to 7680 by 4320, along with frame refresh rates of up to 120Hz, double that of most current HDTV broadcasts. The format also calls for a broader palette of colours that can be displayed on screen. The video format was approved earlier this month by member nations of the International Telecommunication Union, a standards and regulatory body agency of the United Nations, according to an official at NHK, Japan's public broadcasting station, and another at the Ministry of Internal Affairs and Communications. Both spoke on condition of anonymity."
Same old shit in high resolution! =D
I am going to wait for CSUHDTV
Crazy Super Ultra High Definition TV.
We have Bluray that can pump out 40 Mbps and a new High Efficiency Video Coding (HEVC) standard coming that support 4K/60Hz video at around 40 Mbps
We also have a few 4K displays just starting to appear.
And now a UHDTV 4K video standard (as well as 8K).
So looking good for the new gen with broadcast, storage, encoding and display standards all sorted out .. bring it on !!!

We have a couple of 720p (not 1080p, 720p) TVs in our house, a 32" LCD, and a 50" plasma (hey, 720p plasma's cheap.)
How decent is 720p? Well, both TVs appear to be about the same quality as, or often a little higher than, watching a friggin' movie at the cinema, if the source is decent and relatively free of artifacts.
I think, for the most part, we're talking diminishing returns at this point adding pixels. So I'm a little baffled by this announcement. Is it real? Is there a serious market for TV for people with super exceptional eyesight? Is video compression technology really going to improve so much over the next ten years that this'll be worth using - especially over the Internet, which, let's be honest, is where everything's going at the moment.
I'm glad to see innovation, but I'm just finding it hard to believe that this improvement is significantly useful: arguably, like Blu-ray, it might actually hold back HD, rather than help it.
You are not alone. This is not normal. None of this is normal.
The fact that real work is done with lots of text, and text goes from top to bottom far more frequently then scales off endlessly to the right?
We have these stupidly huge 16:9 monitors today that can't even display one page of a PDF without scrolling and yet 2/3 of the screen is sitting empty. It's a terrible aspect ratio for computers.

Not useless for everyone, just you.
Even so - there are monitors that pivot from portrait to landscape. 16x9 is great for office work if you rotate it 90 degrees.
I think the GP is referring to the fact that once we had a high resolution TV spec, pretty much all panel manufactuers decided that "what's good for TVs is good for computers" and no longer make any higher resolution than 1920x1080 unless you're willing to spend close to $1000 or more.
I see no reason to expect they'll do otherwise in the future, so any future TV resolution spec has immediate implications on future computer monitor resolutions.
What you're talking about is little to do with resolution so much as colour gamut, accurate reproduction and (yes) true 3D.
Also your eye is pretty bad unless it's looking directly as something. Then that thing comes into focus because you focus on it. That can't happen with a screen showing already-chosen focus on something else. So no matter how you squint, your eyes can't get the background trees into focus when they pass over them (and thus it's not "real") - and they probably pass over them several times a second while you're watching content that you've never seen before.
What you're saying is that watching a flat box showing colour reproductions of pre-recorded 2D imagery isn't like "real-life". And it isn't. Because even the best colour elements in a TV can't replicate real-life (and some people can even perceive UV and not know it!), even the best 3D TV can't provide depth to the image sufficiently, even the best camera doesn't record everything in "focus-free" format so that you *CAN* focus on any part of the image you like, etc. etc. etc. In the same way that Stereo, 5.1, 7.2, or anything else you choose cannot accurately reproduce an arbitrary sound in an arbitrary location around your head.
The room for improvement is not in resolution. You honestly *cannot* resolve it at a decent distance with a pure datastream (companies badly compressing video? That's another issue entirely). Even though you *can* see the light of a candle in complete darkness from MILES away, you're not measuring the same things.
The best room for improvement would probably be proper "free-focus" imagery. Where you can put up an image and I can see EVERY pixel in pin-sharp detail whether it was one mile away from the camera or one inch (and not have to refocus my eyes, or to fool them sufficiently that they AUTOMATICALLY refocus themselves). Because that pixel element behind the actor's shoulder ISN'T REALLY six foot behind the one that represents his shoulder when it's displayed, so it will not look "real".
Until you have proper, full, 3D and such free-focus media, you won't get what you want. And we know how well 3D has gone down - just as well as it does every time it's "reinvented" for another generation.
The BBC and NHK collaborated to demonstrate this system during the olympics , broadcasting to 3 sites in UK , 2 in US and 2 in Japan.
Further detail See http://www.bbc.co.uk/blogs/researchanddevelopment/2012/08/the-olympics-in-super-hi-visio.shtml
The opening/closing ceremony were broadcast live whereas during the rest of the week a daily hour long highlights package covering the opening ceremony and specific events package was compiled and broadcast on a daily basis.
I was fortunate enough to experience the system at Bradford Museum of the Moving Image on a 15 metre square screen and a couple of megawatts of sound..
With reputedly only 3 cameras in the world camera angles were somewhat limited, the opening ceremony coverage placed you in the heart of the stadium as if you were an audience member showing off the wide field of vision offered. I found the 22 channels of sound to be somewhat overwhelming in volume which I judged to be a bit of a cheap trick to impress. As with initial experience of Hidef the enhanced resolution can lead one to examine detail towards the edge of the field of vision. I was slightly disappointed that there was some blockiness at the edge. This may be due to focussing issues, focus is performed away from the camera.
All in all I found it quite comparable to the Imax experience excepting lack of 3d.
Ever since TV and computer displays became essentially the same thing, the consumer market has dominated.
Recall, if you will, all the build-up to the "Grand Alliance" that gave us today's ATSC (HDTV) standard. There was politicing on Analog vs. Digital (kind of a no-brainer), on RF modulation (we lost out on that one, here, 8VSB was selected due to Qualcomm lobbying and the fact it interfered less with existing NTSC broadcasts... now that those broadcasts are gone, we still have the problem that the signal isn't worth a damn indoors). And on display resolution.
Hollywood, Inc. wanted a 2:1 aspect ration. The computer industry, savvy enough to understand the impact of millions of consumer displays at higher-than-existing PC resolutions, wanted something more boxy. 16:9 was the compromise widescreen aspect ratio.
The PC industry, naturally, went full steam ahead... at 16:10. Silly PC industry. This lasted for awhile, but ultimately, with all those consumer LCD panels out there, most cried "Uncle" and went 16:9. I have dual 1920x1200 16:10 monitors at home, though I see an upgrade to 2560x1440 in the very near future. At work, they've been 16:9 (dual) for my current and previous job. Hardly useless for real work (and that's more Electronics CAD than video these days, though I did EE-CAD, embedded software, web servers, photography, and video at my last job), and the difference is, if anything, more significant for video work (16:9 monitors don't leave any room for controls on the full-screen video panel, 'cept as an overlay) than "real" work like designing circuitry.
