I know that BBC have done additional unpublished subjective tests, with the aid of a studio, on that matter and I hope that by year’s end, perhaps at IBC 2017 or the SMPTE 2017 Annual Technical Conference & Exhibition in Hollywood, both of which I plan on attending, that the OOTF for any given surround light environment be further addressed and although this timeline may be pushing it for their math wizards, that the results of this new testing yield a precise formula presented in a paper at either of these two upcoming events for public analysis.

Plus……however…..don’t get thee impression that Dolby Labs isn’t also concerned about ambient lighting adaptation and the smart people haven’t been working on their own display management process, behind the scenes.

Au contraire mon ami ……” Since many viewers watch content in a non-reference viewing environment, as appreciated by the inventors, it would be desirable to adjust the display management process according to changes in the viewing conditions.”

But how to get it done?…..
“In an embodiment, display controller (130) may receive information (106) about the viewing environment, such as the intensity of the ambient light. This information can be derived from measurements from one or more sensors attached to the device, user input, location data, default values, or other data.

For example, even without a sensor, a user could select a viewing environment from a menu, such as “Dark”, “Normal”, “Bright,” and “Very bright,” where each entry in the menu is associated with a predefined luminance value selected by the device manufacturer.”

My question is “Will dynamic metadata benefit a high nit display by enabling it to show more detail in a dark scene”?

Thanks for the explanation as I found the horse metaphor somewhat confusing . I hope that the VP from DMS lab of Samsung Research addresses that.

I think something to that effect regarding the value of dynamic metadata for showing shadow detail on consumer displays of varying peak luminances (without having to produce multiple masters at various nits levels) in conjunction with the ability to best demonstrate the highlights of bright scenes (with proper color) was also somewhat addressed by Raymond (the document editor for the SMPTE 2094 suite) from Dolby Labs when he presented at a past SMPTE get together.

I’m not that brave -
https://www.youtube.com/watch?v=l3HZIV56z8A#t=1m52s ; however for the English-speaking Brits, I believe the following is exclusive information as I don’t think that films@59 (http://www.filmsat59.com/work/planet-earth-ii-bbc-1/ ) ever reported the precise post production materials and methods online, so specifically, Planet Earth II was graded in Baselight on a Dolby PRM 4220 monitor which had an internal 3D LUT which allowed it to handle an HLG signal. Learn more about the HLG to PQ transcode on July 12th at this afternoon session ->

Different HDR formats using dynamic metadata for color volume transforms (DMCVT): format war or coexistence?



""Q: HDR10 is established in hardware and software. In terms of Dynamic HDR, on the other hand, there seems to be a format war, face-to-face with various solutions, including HDR10+ from Samsung. Was this foreseen? And how is Dolby positioned?

A [Roland Vlaicu, Dolby VP]: The standardization of Dynamic HDR metadata in SMPTE has been running for several years. Dolby's standard was adopted some time ago. Other approaches are also underway. Samsung's HDR10+ format finally confirms our basic decision that dynamic metadata is essential for a high-quality HDR experience. This is definitely a good sign. Time will tell what will happen with the coexistence of several such formats.
However, I look calmly at such a scenario. Dolby Vision has been available in the market for several years, with over 100 partners in production, distribution and playback. Dolby Vision is far more than just a format. Dolby Vision is an entertainment experience that starts with Dolby Cinema...
We have mastered classics from the '40s in Dolby Vision, and the results are breathtaking…""

Format war or not: it is up to you, consumers.
HDR TV shall support all operational HDR formats, which should be IMHO obvious to the masses of consumers, and therefore to the TV makers:
. a format war brings no benefit for consumers
. it is content that matters most, not content format; any HDR content shall be able to play on any universal HDR TV
. like NTSC/PAL/SECAM or Dolby Digital/DTS/…, HDR formats can coexist; from the TV point of view, different HDR formats are just different TV software.

For precision, I posted this comment several days ago on another thread….

ST 2094-10 Application #1 (Dolby’s dynamic range approach) had just recently passed FCD ballot and was in the process of comment resolution (keeping in mind when all comments are resolved the Technology Committee shall conduct a Consensus Vote to elevate the document to Draft Publication). So, I think It’s more accurate to say that Dolby’s dynamic range approach has been adopted by SMPTE for more like very close to one year.

Yes , and I'm a big advocate of dynamic metadata for movies, but something to also keep in mind is that at the current time and arguably even into the near future, how often do dynamic metadata approaches translate into a noticeably superior viewing experience? - https://forum.blu-ray.com/showthread...e#post13712531 especially for those actively involved in watching the movie and not pixel peeping or playing mastering technicians at home.

What I’m getting at is that I don’t think recent purchasers of non-Dolby Vision capable TVs and players should be crying in their soup with buyer’s remorse and feeling unfulfilled. If anyone feels that way, watch some Ultra HD Blu-ray movie like John Wick Chapter 2.

Also consider the fact that despite the new Panasonic OLED (EZ 1000 series) not having Dolby Vision support, it has been approved as a reference/client monitor (for editing, Q/C, etc.) by Deluxe, Company 3, eFilm and Encore. That combination of facilities represents a boatload of post production work.
