8K by 4K or Octo HD - the real SUHDTV technology

8K for the consumers will not happen for a long, long time. 2025 at the earliest. Absolutely no infrastructure in place to make it happen. 4K will be hard enough to make happen, but at least there is already infrastructure in place. I.E 4K cameras, blu-ray manufacting, ultra high speed internet, Movie Studio masters in 4K. There are exactly 3 full rez 8K cameras in the world right now all own by NHK in Japan.

Actually, I think you will find that 8K is 16× HD (I am unsure on the correct prefix) with its 7680×4320 resolution.
Any Sytech is absolutely correct with his post. 8K is not happening any time soon, let’s wait until 4K OLEDs are beginning to materialise and then be made available at affordable prices first.

It’s probably like the other demos Panasonic have done in the past where it’s really four 4K panels put together in one display rather than a single 8K panel. Whether it is or not, it doesn’t change the fact that it is not happening any time soon.

They could team up with Sharp (who probably has a lot of solar panels they can't sell right now due to the high yen) and claim it's "green" by offering it with 1 kw of solar.

1920×1080 =   2,073,600 (1×)
3840×2160 =   8,294,400 (4×)
7680×4320 = 33,177,600 (16×)

Irkuck continues to confound me by starting new threads that he is totally cynical of.

As a pro-4k guy, I have to say 8k is an overkill, simply because of the size and viewing distance required which is likely to be beyond the normal city dwellings.

I think the point is that 8K should look good at any size or viewing distance. At larger screen sizes, 4K is not going to look any better than current sub-60″ 1080p displays. Having more resolution than you need is never a bad thing, and I am definitely looking forward to 8K displays. I can’t imagine them being released any time in the near future though.

LOL - how about just 2K OLED large panels. You have to crawl before you walk.

The proper moniker for NHK's 8K is Super Hi-Vision BTW.

City dwelling helps. Smaller apartments mean sitting closer to the display. That is crutcial for both 4K and 8K:

Do you have any evidence that NHK plans to release it's Super Hi-Vision format earlier than 2020? There is plenty of evidence for that date

irkurk, in case you weren't joking I would point out that there is no such thing as "Super Ultra HDTV". There is simply 4K UHDTV and 8K UHDTV. Also 120 fps is supported at both 4K and 8K as seen in the official UHDTV standard. Are you trying to argue against the idea of 4K TVs by stating that there will eventually be 8K TVs? That doesn't seem logical since there is a huge TV size range where 4K would make more sense than either 2K or 8K.

The NHK is promoting "Super Hi-Vision", which is 8K UHDTV with 22.2 channel audio, but from the various articles I have read I think most of the world will move towards 4K UHDTV.

The people at the ITU who made the UHDTV standard use the term "8K UHDTV".

Super Hi-Vision: the future of TV that's 16x HD

http://www.techradar.com/us/news/television/tv/super-hi-vision-the-future-of-tv-thats-16x-hd-1091821

Sharp has already shown an 85" Super Hi-Vision display:

http://www.engadget.com/2012/01/11/sharp-8k-super-hi-vision-lcd-4k-tv-and-freestyle-wireless-lcd-h/

We have already discussed this at length in the 4k thread. But just even looking at your picture... how big do you think the wall has to be?

LOl - I think you realize that the sizes of the images in that photo have been . . . exaggerated a bit.

"a bit" is right... nonetheless it is representative. The Digital Cinema picture looks roughly like 100" screen with respect to the humanoid. Again, how large do you think an 8k screen will require for say 1-0.75X picture height?

8k for movies and conventions may make sense. Not for mere mortals in city dwellings.

That DC image is 200+", not 100". I know - I used to have a 16x9 144" screen and it was WAY smaller than that DC image.

So you thnk an 84" display is too big? That's what the CEMs are showing for 4K and again Sharp showed an 85" 8K display.

Remember, people are going to be sitting 6 feet away from those kinds of displays.

I don't think 84" is too big. In fact for the past 2 years I have been saying optimal size for city dwellers is roughly 80" and I am a proponent for huge TV.

But I am not unrealistic. 8k TV require much larger TV size and uncomfortable seating distance to be perceivable. Heuristically, if you get any layman to place a sofa vs the TV, it would likely be about 10-12' away.

The market is strongly ignoring even 70" TV at this point; I'm not clear why people are again bullish on even bigger screens. Sharp's 70" sets are even cheaper in year 2 but are poised to manage <0.2% of the global TV market in 2012. Obviously, this could grow over time. But it's not like some sort of technical revolution change the equation. I mean it's simply bigger TV. And buyers are staying away in droves.

They used to say the same thing about HDTV . . . you need a BIG display. Yet the most common size sold is 36/42"

Then you have the differences in the amount of pixels in each display:

HD: 2MP
4K: 8MP
8K 32MP

Where many are saying that sitting 10 feet away from an 84" 4K TV doesn't look much different than a compatiably sized HDTV, those that have seen 8K don't say that.

According to the last NPD numbers I saw, the 50" and above size HDTVs now represent 1 out of every 6 sales.

Everything I have read says 8k is the holy grail of high resolution displays. The human eye cannot perceive any higher rez.

I think over the next 5-10 years the trend will be to up to 70-90" screens so the higher Rez will illustrate itself in most homes. In the 6-10 years before 8k is available for home consumption, most folks will have evolved to their second gen hd set, and they won't be staying at 36-48" screens but will be looking to double that.

If it were me, I'd pass on this new consumer versions of 4k, unless you're a 3 d fan, and hold out for oled (first), and then 8k (next)

So what you are saying is that 8K looks indistinguishable from real life?

How much are those 70+" HDTVs going to cost? What's the cheapest price for a 65" HDTV today?

Consumers are having issues spending $100 for a BD player and paying the upcharge over what a DVD costs today. What is going to motivate them to start spending thousands of dollars for an HDTV when most today look to spend less than $1000? Do you see the economy maiking a huge improvement in the next 5 years? I don't.

So, what will be available in 2025?

HDTV and 4KTV.

SD is still with us right? It's over 60 years old. LOL - it will probably be around in 2025 too.

So, for the next 13 years, the only improvement will be a technology that will be available for sale by this christmas?
In a year or so when everyone is making OLED and/or 4K TVs until 2025, there will be no new technological advances in Televisions.

OLED is a technological advancement. Could easily replace LCD and PDP in the not too distant future.

Autostereoscopic 3DTVs (no glasses) will be coming in the next few years - definitely a technological advancement.

Sony's Crystal LED would be a technological advancement.

4K LCD TVs are an evolutionary change (IMO)
