Well, the only one I heard about. Either way, I'm sure there is not going to be a 4k projector under $10,000 this year or next that reaches rec 2020. Even the Sony 1100es does not reach rec 2020 and that's almost $30K

That model doesn't meet Rec2020. Even DP's own marketing shows it doesn't meet it. It comes close like all the other LED models. The light source majorly controls if the projector will get to REC2020 or not. The current types of LEDs used just come shy of REC2020.

Here's an image I put together:



As you can see, it misses both blue and green and tapers the triangle on both those sides to miss a lot of other color points.

If they list P3 AND 2020 in the standard there will have to be some meta-data sent with the video information to tell the display to switch over to a different color gamut. Because playing P3 color graded video with a display in it's REC2020 gamut will have incorrect colors which is why they need to be remapped.
Yes, I would suspect (hope!) the meta-data is present for each gamut. Initially, I would suspect just P3 for the first several years. At least 2020 is in the spec for future potential implementation.

Well apparently it was good speculation:

SMPTE 2086:
"Project scope:Develop multi-part standards for specifying the semantics and representation of content-dependent metadata needed for color volume transformation of high dynamic range and wide color gamut imagery to smaller color volumes (e.g. BT.709 or Digital Cinema) in mastering applications."

I think this new UHD standard is seriously pushing the limits of current technology. There will need to be SOOO many work-arounds to get this format to work on legacy and non-compliant UHDTVs and projectors.
It is pushing the limits, but properly handled (ala SMPTE 2086), I think that's a good thing. I mean how many of us wish or thought that Blu-ray should have included support for P3 or 10 bit color. Whatever is in the Ultra HD Blu-ray V1 spec is basically going to be what it's going to be forever. I mean how many studios/content creators will take advantage of Rec2020 in five years it it won't work on all installed Ultra HD Blu-ray players?

Also, don't forget, that the discs themselves aren't required to be Rec 2020, so the studios can just take their DCI masters and they should be able to map them almost directly to Ultra HD Blu-ray.

I'm excited about UHD Blu-ray, I'm glad to see they're creating an ambitious spec, especially after being somewhat underwhelmed with the overly conservative Blu-ray spec (Rec 709, 8-bit, 4:2:0 color, max 1080p30). This Ultra HD Blu-ray spec should be good for quite a while to come, even if it's not all practical for displays today.

The only issue I see with this is that the SMPTE 2086 standard is still in development. What happens when the BDA finalizes the UHD BD spec before SMPTE finalizes this standard and is not included in the BDA's spec?

SMPTE 2086 was officially completed in October of last year and for some money you can even download it. The standard was technically completed about a year ago which is when it was added to the second version of HEVC.

A method for gamut mapping was added to the second version of HEVC last year and my guess is that is what Ultra HD Blu-ray will use. For the next few years I would expect the studios to use DCI P3 since that is the current standard for movie theaters.

Interesting. Thanks for the link. They must have forgotten to update that page. This page says it's estimated for completion in September of this year:

https://kws.smpte.org/kws/public/pro...project_id=294

Is this a different project?

That project is for creating a gamut mapping standard for professional equipment. They could simply use the gamut mapping standard that was added to the second version of HEVC but my guess is that something more complex, and more expensive, will get chosen for professional equipment.

Does anyone know if it's been confirmed if the existing PC drives that support BDXL will natively be able to handle ULTRA HD BLU-RAY? All I see are assumptions, no actual official press release stating that BDXL will be format.

I'd worry about software to actually play them a lot more than if the drives are physically capable of reading the discs.

I believe the format is the same, but the current drives would probably need at least a f/w upgrade to support the new UHD Bluray discs, so I would wait until BDXL drives advertise full UHD Bluray compatibility (or early adopters/existing owners report full compatibility) before buying a specific model. That's unlikely to happen until the first discs are released towards the end of the year.

Then you would obviously need not only software to be updated to play the discs - either licensed like PowerDVD or unlicensed like jRiver, XBMC, MPC-HC etc once/if HDCP 2.2 protection is cracked - but depending on the power of your CPU you might also need a GPU supporting hardware acceleration for HEVC, as well as supporting HDCP 2.2 to be able to use a licensed player.

So I do plan to upgrade my HTPC with a BDXL drive and a GPU supporting HDMI 2.0 level A, HDCP 2.2 and HEVC h/w acceleration, but the products are not there yet.

In theory though, this will be all you need to be able to play UHD BD on a PC.

The big question is whether the BDA would grant a license to an official player like PowerDVD, as if I remember correctly it is licensed players on PC which allowed to crack the last HDCP version. They might have learnt from that...

Yeah I figured on a new video card supporting HDMI 2.0 + HDCP 2.2, along with HEVC decode. Just will suck if the current BDXL (and I've got probably one of the first in another machine I have) drives won't get firmware updates that make them support it.

To be clear HDCP has nothing to do with unlicensed players, AACS/BD+ (or whatever new creative disc-based protection system comes out) needs to be circumvented for unlicensed players to work. But I find myself wondering if there will even be a UHD version of PowerDVD or WinDVD (the only licensed players left). And assuming they don't just use current AACS/BD+ (I can't imagine the paranoid studios giving in and sticking with broken encryption) how long before there's a workaround?

The bigger question is will Cyberlink or Corel even try to get licensed.

I'd be surprised if Cyberlink doesn't at least attempt to get a license. They've been pretty good about making sure that their software is updated with the latest features, so that they can justify a new version every year and charge existing users to upgrade. I don't see how they could continue to make and sell new versions of their software if it never makes the transition to supporting native 4k. They jumped on the 4k upscaling bandwagon a few versions back and have been quick to add HEVC support.

Something else to consider is that playback of the film directly from the physical disc might not be the only source from which you can get the full quality version. If the "digital bridge" copy is a full quality download and it's compatible with PC's using licensed playback software then you wouldn't even need to rip the discs anymore. Supposedly, PowerDVD already supports playback of your Ultraviolet library. So, it's possible that they could end up going the digital download/streaming route and not support playback of the content directly from the physical Ultra HD Blu-Ray. However, I don't know if they can really make money selling software to do that if other providers like Vudu are giving the playback software away for free (as they make their money on content sales). The only thing they would offer at that point that Vudu does not is playback of your existing DVD/Blu-Ray disc collections and any other video content you have on your PC/Server.

Wonder if they'll try to push the interactive online features again. They tried it on a few discs but unless you got the discs at release, a lot of those features weren't available.

Not sure if they are still making discs with online features.

If they want to make the product more attractive, they will get rid of the Java layers that make disc loading such an arduous drawn-out process.

Wow. Since they put in Cinavia and I stopped updating my version of TMT*, I haven't been keeping up with Arcsoft news. I didn't even know they stopped selling it until this post.

*I don't even pirate anything and I use ANYDVD (to skip trailers and such and defeat some region coding for imports. And previously to defeat HDCP for my old monitor that didn't have hdcp), so Cinavia wouldn't even affect me, but on principle alone, I didn't want to update TMT to support Cinavia.

rec 2020

Looking at the "leaked" Panasonic slide from CES on UHD blu-ray, http://www.flatpanelshd.com/news.php...&id=1422517486 , and reading it literally, it looks like the only color space for UHD is rec 2020.

I would interpret that to mean that smaller color spaces (e.g. rec 709, P3) would need to be translated to rec 2020. Then the player would have to convert to the display's color space. Of course, I'm guessing here, but if this is the case, I would think 10 bits is a bit (or 2) shy to represent the rec 2020 color space without banding.

Hopefully the slide is incomplete.

BTW, for those of you concerned about no 48 fps UHD in the spec, there is no 4k 48 fps in DCI (48 fps in DCI is 2k only).

Luma banding or chroma banding? The luma channel isn't any wider with BT.2020 than it is with BT.709 (unless you're using HDR, of course). Only the chroma channels are wider. And the chroma channels are less important. So, IMHO, 10bit is ok for SDR (although I would have loved to get 12bit). I'm worried about HDR bitdepth, though.

When I see banding - it's usually with artificial (computer generated) colored gradients. So slight color changes from one shade to another. It results in the same 8 bit values for an area, then a change of 1 lsb for another area. Your eye easily picks the 1 lsb up and you see bands. This is easily fixed by dithering the lsb (e.g. in such a way that the average over an area of several pixels is the same as the average of the underlying 10 bit desired values - but this is often not done).

Maybe with 10 bits to encode the color dif channels (vs 8), it's enough to not see banding, I don't know.

Don't forget that UHD BD is also supposed to be using the SMPTE ST 2084 Perceptual Quantizer trasnfer function which is much more efficient than just a "straight" gamma curve like Rec709.

I know what you're talking about, but that's usually on a luma gradient, eg light blue to dark blue, can't say I've every noticed banding going from highly saturated blue to less saturated blue. And remember too that 10 bits is four times as many codes available per channel, 64 times the total number of available codes than with 8-bit coding. Combine that with a PQ transfer function and I'm not worried about banding.

It's probably not the color changes your eye picks up, but the brightness changes. With 10bit BT.2020 you have 4x as many brightness steps between black and white compared to 8bit BT.709. So visible (brightness) banding should be much lower. Chroma banding should be higher, because BT.2020 is wider than BT.709, but I'm not sure how visible chroma banding is. I think it's probably much less obvious than brightness banding.

Combine that with a PQ transfer function and I'm not worried about banding.

I think it's probably much less obvious than brightness banding.

Points well taken.
