HDR Discussion Thread

[DanBa]

Thanks!

As far as I understand, Dolby Vision for cinema and Dolby Vision for home use the same SMPTE ST 2084 PQ.

Dolby Vision for cinema doesn’t have dynamic metadata because the projector for the theatrical grade and the projector in a Dolby Cinema theater are the same type: no need to carry out the color volume mapping.

I will add EclairColor and IMAX Laser HDR as soon as they are using for home.

They use the same basic system but they are of course NOT the same grade, with theatrical DV @ 108 nits whilst the home iteration can hit 10000 nits (though 4000 is what's indicated above).

It'll come by way of firmware update to the affected TVs.

This explains, too, why I and other 4K Blu-ray fans have also sometimes seen the same sort of raised black level issues when watching Dolby Vision 4K Blu-ray titles.

Hahaha the only hdr10+ content in the world isn't even hdr10+..... i almost wish heat hadnt been banned now, just to see him spend a dozen posts and Antonio banderas memes trying to downplay it.

I think you are right.

Yes, give me a few moments to check out the rest of the posts on the page and I’ll write up a short spiel on what fancied our interest.

I'm genuinely curious to know what he means by this.

Since Amazon isn't using the "final" version, is Samsung/Panasonic/Fox planning to update the format in some way?

Also, and maybe 2themax can shed some light on this, is the version of the format that was accepted by the BDA the "finalized and fully signed off" format?

Or did he have some hot roulette numbers to stake out?

I think this booth really attracted those CES regulars still suffering from withdrawal since 2012 due to the absence of the coexistent AVN Expo (https://www.cnet.com/news/how-will-c...ut-porn-stars/). Plenty of folks ventured in to see what it was all about (including me , for that matter, though I was never motivated to visit the AVN Expo back in the day).






Any guesses as to what they were promoting inside?

Mind you, as a stakeholder.

Seen an article about this supposed controversial demo yesterday on the daily mail UK website.

I was hoping it would be Mr. And Mrs. Bixby by Samsung

Fox told John Archer that the earlier possible time they could have hdr10+ disc's is March. And they are supposedly way ahead of Warner Brothers.

After I flew cargo*, my wife joined me at CES just a few hours later and most enjoyed the LG rollable -

LG Rollable OLED TV Display - Hands On at CES 2018 - YouTube

This ^ tech should be scalable to even LARGER sizes, e.g. 100” with time.

Taking a leadership role into thee most significant parameter of Ultra HD Phase 2, I really liked LG bringing more awareness to the assembled press as to the value of native 120/100 fps input and rendering out . Which means that 2018 LG tv owners should, until more content becomes publicly available, at least be able to properly view this demo - https://forum.blu-ray.com/showthread...e#post14556365 in order to gain some insight into the clarity gained with increased temporal resolution.


As to Sony and the futuristic X1 Ultimate processor, it can also handle native HFR as well as boasting other qualities as mentioned…..

Fundamental question (this should be simple for the gadget dudes, but at CES they were clueless) -

What natural occurrence is close to 10,000 nits?
(the original developers of HDR(EDR) on the tech staff at Dolby Labs liked to make reference to this back in the day to professional working groups, but I’m not sure if it ever made it into the plethora of marketing info about HDR on the internet)

I wouldn't get too concerned because the earliest runs of x format are often done using a jury-rigged system to replicate the effects of x format rather than actually being the final product, and streaming has that advantage over a physical disc format in that they can alter their streams and masters as they see fit.

But the BDA won't have approved a half-finished edition (though is that actually official yet?), it needs to be set in stone so that the relevant formulae and whatever can be laid down into the authoring spec. I'd look to Amazon for answers as to what their "version" entails rather than ask questions of Samsung/Panasonic/Fox.

NBC Olympics will distribute the 4K HDR coverage, provided by Olympic Broadcasting Services (OBS) and Japan’s NHK, to U.S. distribution partners who will individually choose how they will make the content available to their customers."

The sun's direct light on a metallic surface is around 10,000 nits.
