What is super hi vision? UHD, 4K & 8K TV

Unlike 4K and 8K, which are purely visual standards, the Super Hi-Vision system also has three-dimensional 22.2 surround sound, with three vertical layers of front speakers, two layers of surround speakers, and two subwoofers for bass frequencies.

Conventional home cinema systems are 5.1, with three front and two surround speakers, although we're now seeing 7.1 audio with four surround speakers, and simple three-dimensional speaker options for the home.

Here's how Super Hi-Vision/8K Ultra HD lines up against 4K Ultra HD and Full HD.


CREATOR: gd-jpeg v1.0 (using IJG JPEG v80), default quality

That "8K capable camera" seriously looks like it has a Tokina 11-16 on the front.

24 Gigabits/second. Dear friggin'... I want to see the color grading setup for that.

Holy moly...

There is always a limit on usage. You can make a phone size of TV, but no one will use it. And what is 22.2 audio channels? This should be build on 7.1 system than, no way I will put more than 7 speakers.

That's equivalent to 3 gigaBYTES per second. You'd need at least six 1TB Crucial M500's in RAID0 to support those writes. And they'd fill up in about a half hour.

This is so you can sit with your eyes exactly 3 inches from the screen and still have a quality experience.

Titles available include "Frog Blinking Eyes," "Flying Above Arboreal Region," "Random Athletic Endeavor," and the classic "Time-Lapse Flower Blooming."

I actually got to see Sharp's 8k display at CES 2012. It was absolutely amazing. By far it was the coolest piece of technology I have ever seen to this day. So I really can't wait until this becomes mainstream.

What, about 2030?

I would say a lot earlier than that! Probably like late 2018 - 2020, somewhere in there. Look how fast we upgraded tablet screens to "retina", or how fast we went from 1080p to 4k. 8k isn't really an insane concept considering they can make several 4k monitors in the 20-30" range for under $1000. Last year when a 30" 4k was over $5000 I wondered when we would see an affordable price.

Since they have already had a working 8k for over 2 years, it's only a matter of time before it becomes affordable especially in the next 4-6 years.

I mean seriously. Do the manufacturers know something we don't?

Nooooo way lol. 8k is like playing on 16 1080p monitors, so no. They have done gaming on 3 4k monitors (75% of 8k) like in this video from CES this week:

Still a while off from that kind of computing power, but hopefully all this new emergence of 4k will spark some innovation at Nvidia and AMD.

Or four PCI-E lanes and a decent RAID controller connected to four M2 NGFF SSD's...... this is about to land on the market as consumer/enthusiast product this year.

dunx

8K is cool and all, but we are still 5-6 years away from such thing coming to the mainstream. First we need to solve SSD read and write speed problem, we should get at least 5x faster and 3-4x the capacity for this type of video and game resolution. Then we also need to drop down to around 10-14nm in size for GPUs so that we can fit enough render pipelines and shader processors to actually ruun 8K at 30fps minimum on a single card. And dont forget ratifying PCI-E 5.0 or whyatever tech replaces PCI-E, and the CPUs to support that kind of graphics slot bandwidth. So 5-6 years is a pretty quick estimate in my opinion. it will seems funny to us now thinking of a single GPU with 20GB of vram and 256 ROPs, but that will probably be what is required to run an 8K resolution game on a single card.

Yes, this is only ideal for large displays.

5-6 years its not going to happen. 4K will be in 5-6 year. Even though people will start to buy 4K screen now you will not be able to get 4K contented for some time. 4K movies ~ 100GB.

1080P is just making it's way to the desktop and appearing more and more in living rooms but don't fool yourself 2 years ago most of the people still had 1600*1200 or 1080i or FHD ready tv's or just HD tv's to make a long story short adoption took a long long time.
Only if it is cheap people will adopt it so I think it'll be till 2020 for 4K UHD to become really mainstream and after that we can start shifting to 8K.

So a lot of people on here always says moar pixels are better, but at some point soon the human eye will reach a limit. I'd argue that you only notice half the improvement each time you double pixel density.
So jumping up from 2k to 4k gives you twice as much percieved improvement compared to 4k to 8k assuming an similar area. Same thing for 16k or 32k.

1080p on my desktop already makes movies and games look real basically and although absurb amounts of resolution is cool for novelty, it doesnt really offer substantial aesthetic or pratcical benefits . it simply requires more processing power, which needs more electricity, etc. My point is that it isn't worth the electricity increase. I'd rather just have higher power saving than moar pixel density beyond 1080p.

You missed my post. It's so you can sit closer to the screen, providing the illusion of optical immersion that is only achieved by much more practical and less expensive means, while simultaneously activating the brain's photosensitivity receptors for maximum subliminal marketing capabilities.

you clearly have never had a 1440p or higher monitor before. On paper you can say it wont make that big of a difference, but in person it makes a world of a difference. Anyone who multitasks be it video/music/photo editing, coding, massive spreadsheets and data entry, or just watching a video while browsing a few websites will be able to appreciate the extra real estate.
