ITU approves 8K ultra HDTV specification

The International Telecommunication Union, a standards agency of the UN, has approved a new television format which boasts a resolution of 32 megapixels, which is 16 times bigger than the current HDTV standard. The new ultra HDTV 8K standard, also known as Super Hi-Vision, was partially developed and demonstrated by The Japan Broadcasting Corporation, better known as NHK.

Super Hi-Vision offers a resolution of 7680 by 4320 pixels at 120 frames per second. Smaller frame rates such as 25 fps are also included, but only progressive frame rates are allowed. Just like the current HDTV standard, there's also a smaller format included in the specification which has a 3840 by 2160 resolution. What kind of audio specification will be used together with the ultra high definition material has not been decided yet, but the NHK is supporting 22.2 surround sound. However there is more work to be done on how to transmit and store the 8K video.

According to documents published by the ITU, the standard was made for use at home as in public spaces such as cinemas and big venues. At the 2012 Olympic games, NHK showed off the technology and developed three special cameras to shoot the 8K video. In 2020 NHK plans to begin it's first experimental broadcasts in 8K format.

Several Japanese electronic makers already have some 4K devices on the market. LG will start the sale of a 84 inch television for about $22,000 very soon and Sony and JVC have some 4k projectors on the market, which are used by digital cinema cameras.

Who the hell buys an 84" TV for their lounge shoot I'd have to sit outside to watch the damn thing otherwise I'd be constantly moving my eyes around to see it all and probably miss half of what was going on

I have a home theater projector with a 100" screen. I think our normal viewing distance is about 12ft or so, so its not exactly a huge room. Honestly anything smaller just wouldn't feel right, we use it for watching football and its one of the best buys ive made. It sounds crazy, but that size at the distance we watch it as is perfect.

also, directv has these "mix" channels that shows 8 games on the screen at the same time just like you would do split screen with a video game. On a normal screen something like that is just stupid and you cant watch anything, but on a 100" screen all of the split screens are like 32" so it works really well.

I can't wait for the 3d tvs that support this resolution! /s

Not sure what the sarcasm is about. 3D has improved and it is only going to get better. It still has some faults, but your sarcastic comment really doesn't make any sense.

Its funny how we always went from the vertical side to judge TV resolution, now we suddenly shift to horizontal because it's a bigger number?

How big does a proper hollywood video camera shot?

And how large would one scan negatives before it would be pointless?

Sounds like a 20 year standard to me...then again, you never know. Personally 4k is all I'd ever need, I'm perfectly happy with 1080 most of the time on my 42", but at 55" or more, the extra pixels are appreciated. 8k? That's going to require retooling the industry a bit as well.

"What kind of audio specification will be used together with the ultra high definition material has not been decided yet, but the NHK is supporting 22.2 surround sound"

Well, how about Dolby Atmos?
