Support for all HDMI 2.0 specification features, including YCbCr 4:2:0 color space

I'm quite sure that HDMI 2.0 will be able to handle 2160p in RGB/4:4:4 though. It would be pointless if it did not.

2160p RGB/4:4:4 8-bit? Yes
2160p RGB/4:4:4 10-bit? No

Disappointing.

What happens if 4K Blu Ray DOES come out but it supports 10 bit color through hdmi 2.1. Does this mean that HDMI 2.0 will be incapable of playing/displaying this format? will it downscale the color and still play at 3840x2160? Or does this mean that HDMI would be incapable of displaying this signal? All theoretical of course smile.gif

Encoded video formats are all 4:2:0, so that's not a concern. It's actually smart that they now allow the video to be passed unscaled, as it saves on bandwidth.

4:4:4/RGB only applies to video that has either been scaled externally (generally in the player) or sources which are RGB native i.e. games consoles and computers.
It sucks that they only support 8-bit RGB and not 10-bit though. I've been waiting for PCs to move away from 8-bit for years, and this is yet another thing stopping progress.

So is the general consensus on this site that hdmi 2.0 will be able to accept the next disc/video format for 4k movies (if there ever is one)?

Or will I buy an hdmi 2.0 display and find in 2-3 years that when 4k content is available, I won't be able to watch it?

HDMI 1.4 was probably enough. There's not going to suddenly be an influx of 60fps content, films will still be 24p.

All test 4K broadcasts have been at least 50 fps. Once real "4K" broadcasts start there's going to be a lot more 4K at 50/60 fps or more. Films will be different frame rates, including 120 fps smile.gif.

LG will provide UHD sets with built-in HEVC decoder still this year. Thus, with the HDMI 2.0 and HEVC, UHD sets will become technically mature. That will be also be a solution to the chicken and egg problem with the HEVC encoded content:D.

Looks like HEVC chipset have been finalized and ready to ship. We now have HDMI 2.0 and HEVC in place, as well as rapidly falling 4K display prices. Still waiting on the Blu-ray association to announce 4K disc standards or for Sony/LG/Toshiba to do their own.

Another BRCM chip that supported 4k and HEVC was annouced at CES last January. More press the better I guess biggrin.gif

So technically the BDXL drive in the PS4 can read triple layer 100GB and even 128GB quad layer BDXL.So it should be able to read pressed triple layer BD. Most reports from people with Sony Media server are reporting 40-50GB 4K movie files using eyeIO's custom h.264 4K codec. So if they switch over to universal HEVC codec the file sizes and quality may double to near the 100GB capacity.

Agreed, and it is likely that consumer video will continue to be encoded at 4:2:0.

DisplayPort is an option for computers and I think the biggest problem with getting 10/12-bit computer programs is that currently most consumer computer monitors are 6-bit LCD.

If true that would be good news.

I stumbled upon this 4K TV sales forecast which predicts 7.000.000+ worldwide sales by 2016. 4K (Edge Lit LED LCd) is most popular in China which is kind of weird since more than half of the population over there is poor confused.gif

If it was a real prank wouldn't they see that the perspective of the scene outside wasn't changing when they moved? Also the dynamic range of real life would be a lot higher than a TV. And the frame rate too low + it's 2D.

They used actors in their fake elevator prank, http://www.youtube.com/watch?v=NeXMxuNNlE8
haven't they done the same thing in this one?

It's meant to be obviously funny--there aren't many people who would believe this to be possible IRL, or Christ I hope not.  Certainly not anyone with much common sense----any window shows readily obviously different amount of scenery with subtle head motion regardless of how far away the objects outside the window are.  It'd be as convincing as a photograph of the outside----moving objects or not.

 

Perhaps I'm over estimating the public, but I sure hope not.

Anyone else feel that 4K is marching right along at a better pace than we previously thought would happen?  I do.

post #3472 of 3670
So there's been "8K" "broadcasts" to large screens (2012 Olympics), and for 2014 there will be "4K" broadcasts to large screens. Seems like an advance in technology smile.gif.
Unless it's to more screens or actually to consumers using actual "4K" TV channel(s).

There will be the same 8K "test broadcast" by NHK for FIFA in 2014.

The 4K broadcast (the real one) will be in the hands of Sony.

The same, but more advanced work-flow and techniques will happen at the Olympics in Brazil 2016, which is the year NHK has for long said they will start full Live test broadcasts.

NHK have always had in their time-line the year 2020 for starting full 8K channel broadcasts, and guess what.....................Tokyo was just the other day chosen to host the summer Olympics in 2020. wink.gif Which will be broadcasted in 8K, has already NHK and Sony confirmed.

And for those that are occupied by framerates........there was quite a lot of framerate talks and conferences at IBC this weekend....................even demos of the difference between 50fps and 150fps.

Nope. Called it right on schedule. Also, called the inability of OLED to produce a mass produced product and the stillborn death of 2K OLED, as marketing hype forced them to make the switch to 4K OLED earlier than expected. That being said, I think I learned things when I got totally burned backing LCOS a few years ago. Namely, that while you can have a superior product at the time, cost, production problems, quality problems and the rapid improvement of your competition all play factors.

And who knows if it will actually be 1080p. They were one of the first major games that was sub-HD this generation. HDMI 2.0 is not a concern for the consoles - it's really only a PC problem right now, and possibly high framerate video content in the future.

Oh look, another game that's no longer running at 1080p - and it wasn't even 60fps to begin with: http://www.neogaf.com/forum/showthread.php?t=679469
Yep, really seems like the consoles will need HDMI 2.0 for 4K gaming at 60fps...

I don't think anyone is under the impression they are going to be doing any gaming at 4K@60hz. At less not without a total redesign of how they render graphics. However, it is important for people the will be watching pre-rendered movies to have 4K@60hz. Also, the PS4 is the more powerful of the 2 consoles, and should be able to eventually run guns with 60fps or less at 1600p.

Why? The vast majority of video content is 30Hz or less.

Even if that was true, "4K" TV is going to be broadcast at 50/60 fps or higher with TV programmes made in that format. Blu-ray 4K is meant to be the higher quality medium. If TV supports 4K at 50/60/higher but Blu-ray 4K or the devices that play it only support up to 24/30 it's not going to be seen as higher quality.

I would be surprised if that happens. I wouldn't be opposed to it, but I just don't see television moving away from 30Hz, or film moving from 24fps any time soon.
