Always have? Even in the pre-digital era? Excluding Super-35 and Super-16 formats (where they would transfer to another film anyway) in the pre-digital era they'd have had to rephotograph the film and losing a generation as well as the PQ loss due to the zoom. Or do you just mean in the days since digital intermediates/digitally shot film/TV?

Not necessarily. eg. if NHK broadcast 2 hours of 7.68K at 100Mb/s (ie. compressed) it would only be around 87.89GB.

Well they're going to have 7.68K TV on a regular basis in Japan (maybe other places too?) in about 5 years.

Joe, can we set aside the pedantry? We are talking about the digital domain.

Using Artificial Life algorithms, I created a bunch of creatures and let them evolve on my system. Over the years they gained intelligence, a society, and quite a few interesting abilities. However, using the rules from their world, they concluded that I did not exist. So I created a special creature meant to spread the Word about Me with amazing magical abilities that only He had. Went well, until they decided to nail the poor Guy to a tree.

Yes. On a broader note, one of the things people seem to have the hardest time with is in accepting that existing bottlenecks (storage size, bandwidth, cpu speed, etc., etc.) do always loosen over time. I even see this within myself when helping someone manage a functional spec. I routinely catch my knee-jerk reaction when reacting to "terabytes" as some kind of "OMG, NO!" limiter, but in reality, terabytes just are not that big of a deal these days.

Wait a second. With deference to the Thread title, are people using SUHD to describe 8K?

Samsung has that as a trademark now for 4K.

Technicaly it's not "Octo HD" either.

Technically their 4K isn't 4K so they're wrong doing that too, since it's 3840x2160.

They talk about "Samsung 4K SUHD TVs". I'm not sure why later they couldn't talk about "Samsung 8K SUHD TVs" (well apart from the fact that their 4K is 3840 and 8K would be 7680 - at lot less than 8000).

Unless it's something to do with "Mark Drawing 4000 - Standard character mark Typeset" in the trademark. Would that limit it to "4K" or does the 4000 mean something else here? Is that what makes you think the SUHD trademark is limited to "4K"? Isn't that just a code - and the trademark is probably just for "SUHD" not also the letters "4K" - so it could be used for 7.68k too?

It's just a term. UHD became generally understood as 3840x2160, and it was in this thread that I first saw the term SUHD used as a synonym for 4 times that. So I have to wonder where common usage is falling with respect to this.

3480 vs 4096 and 7680 vs 8192 are non-issues to me. We're talking about what terms mean, and if 4K colloquially means 3840, then I'm fine with that, even though it causes confusion with the Red camera guys. What I'm not fine with is having SUHD mean both 4K and 8K.

I didn't think this was really a problem. Super Ultra HD is the stupidest sounding marketing term I've heard in a long time, and wouldn't be caught dead uttering it aloud. I will continue to call 3840x2160 by "4K UHD" and 7680x4320 as "8K UHD", no confusion at all if you do that The other resolution known as 4K (4096x2160), I prefer to call "Cinema 4K". Those may not be official names, but everyone knows what you're talking about.

If the Koreans decided to add the word Super to a resolution specification for marketing, that's on them. Just like they created the awful phrase "LED TV" to mean the successor to CCFL backlit LCD. They seem great at creating marketing designed to confuse the average consumer.

I think you're making too much of an acronym expanded meaning. HDMI means "High Definition Multimedia Interface". No one says that out loud, they say "HDMI".

That's even worse, though. "SUHD" sounds obscene to me Something like "SVHS" rolls off the tongue, but "SUHD" doesn't feel right at all.

To me it sounds like a mix of Super-Hivision (NHK's original name for UHD / 7680x4320) and UHD.

Quote:

For a long time there's been 2 different ones. UHD-1=3840x2160 and UHD-2=7680x4320 (UHD-2 based on original Super-Hivision display res). For a while, other than Japan, it seemed UHD-2 was more going for cinemas, but for a while now has been intended for consumers. So UHD means both of those, though it may be currently understood as 3840x2160 just because there are very few available displays that are 7680x4320 (if any). But whoever went to see the demos of 7680x4320 would have understood it as being UHD (unless they were still calling it Super Hi-Vision then).

2K,4K, 8K. That's all you need. Pretty easy to understand and more importantly reasonably easy to explain in a basic way. Lets face it, if you're trying to give a quick explication to somebody that only wants a quick explication then 2K,4K,8K should suffice. Anything beyond that and you'll be watching their eyes glaze over.

Well again, I'm fine with 8K, but that's not my question.

Is there an accepted acronym for 7680x4320 other than "8K UHD", or "8K"? (Again, let's ignore the 8192 argument for now...it's pointless).

The "8K super hi-vision" isn't generally used outside of NHK, even though they're the pioneering force in whatever adoption has happened thus far (almost nothing).

Netflix calls 1080p "Super HD", so I'm sure this is what's tripping some people up. They probably see that and assume that the convention is going to apply to UHD as well. But in the end, "super" this and "super" that is always extraordinarily vague. Super VGA implies next to nothing other than it's higher resolution than VGA.

HD, on the other hand has adopted a somewhat sensible naming convetion based on quarter/nominal/Full/Quad. 8K UHD will be marketed as Full UHD or simply 8K whenever it hits American shores.

My guess would be 4320p.

'“The 8K TV’s appropriate size is bigger than HD TVs of course, more than 4K TVs,” said Hamaguchi. “For home use, 70-inch or 85-inch is an appropriate size.” But NHK’s assumptions will seem peculiar to most consumers. According to Hamaguchi, NHK feels the appropriate viewing distance is 3/4 of the screen height. In other words, they assume that viewers watching a TV about the size he describes, with a screen about three feet tall, would sit just over two feet away from the screen two feet away from the screen. The typical living room viewing distance in the U.S. is about nine feet, and most viewers watch TVs much smaller than he describes.'

I don't know about the rest of you, but with the flexible OLED technology, I would prefer to be wrapped up in an OLED like a burrito for all my video viewing. Curved screens? Pfft! I want to live INSIDE the screen!

I didn't read through that link, but I want to caution that when I've seen similar 3rd-hand claims elsewhere, what they were doing was errantly looking at the NHK charts for where the drop-off distances were, taking THAT information and assuming that NHK was actively advocating it as a viewing distance.

There is no place that NHK advocates 3/4 screen height for viewing.

Using Artificial Life algorithms, I created a bunch of creatures and let them evolve on my system. Over the years they gained intelligence, a society, and quite a few interesting abilities. However, using the rules from their world, they concluded that I did not exist. So I created a special creature meant to spread the Word about Me with amazing magical abilities that only He had.

I think this sort of misses the point. 3/4 screen height is like the first row of a movie theater. Unless people actually want that kind of extreme immersion, 8K is not needed regardless of screen size.
