“stunned the world” is Larry putting it kindly, more precisely, looking back at the ITU meeting in spring of 2012, the submission was met with much skepticism and initially rejected - https://forum.blu-ray.com/showthread...m#post12602993
but later accepted https://www.itu.int/md/R12-WP6C.AR-C-0052/en

look long term

True the HDR10+ production is a relative no-brainer as compared to DV, but with more experience, the DV work it’s not quite as intimidating (PITA) as Tom implies. A Dolby Vision training class was just given about a month ago at the Dolby Labs in New York City and are commonly available in the Burbank office.

For small shops or independents, the major stumbling block remains their initial investment/outlay cost for the complete Dolby Vision workflow pipeline installation (including hardware and software) and the yearly Dolby Vision mastering and playback service agreement.

In case inquiring minds were wondering what that content was on the screen behind the panelists, but were too shy to ask, it was from this - https://www.imdb.com/title/tt5290382/

later, duty calls.

Last month the EBU Videos Systems group organized an HDR monitors testing event.....
The result will be summarized in a report this summer and used to update EBU Tech 3325 and to create new test patterns.

Testing included measuring the monitors’ luminance ranges, uniformity, black level, color gamut, contrast ratio, transfer function, grey scale reproduction, delay time, and more. Pixel defects, image sticking, treatment of illegal signals, etc. were verified subjectively.

Until this summer’s report comes out, it can be revealed that it was interesting to see that the tests revealed a new type of effect, which may be called ‘dynamic burn-in’. It turned out that some monitors still show parts of (repetitive) moving images long after the signal has been removed. As with static burn-in, cleaning signals may be used to remove the effect, but they may be very screen-specific.

Of course, as I explained to folks on the last page, the USA did’nt qualify . The reasons? well, don’t blame Jurgen (https://www.si.com/soccer/2018/05/16...orld-cup-usmnt) nor Bruce (https://www.amazon.com/Coaching-Amer.../dp/0062803948....

which makes the intro pic to this article even the more painful/ironic as a reminder - https://www.tvtechnology.com/news/fo...rld-cup-russia

Until this summer’s report comes out, it can be revealed that -

amongst the tested monitors, the measured video delay varied between roughly 20 and 60 ms which is obviously more critical and significant for certain use cases rather than others.

nobody found that vimeo clip at all humorous ^ ?

It was quite the comedy relief hit as an ‘educational’ trailer among a room full of professionals (paid geeks) during a technical presentation. Oh well, I guess hobbyists are a more discerning lot with regards to such things.

So, if I am understanding this correctly, there are two DoVi improvements that are not being implemented on current DoVi discs. One is ICtCp and apparently the other is frame by frame adjustments. Our future panels will be able to take advantage of the 12 bit encode being done now, so that's a good thing.

I am all for the best picture I can afford, but it would have to be a special movie for me to double dip a DoVi title (or am I just kidding myself ).

Anyway, the future is looking bright for DoVi.

I missed it the first time around - I watched it a few minutes ago and really loved it! Particularly the Christopher Walken line calling back to a certain Saturday Night Live skit. Pretty decent impressions, too. Thanks for the link!

D-Nice baby! Man, that’s a blast from the past. Last I remember of him was from years ago when he gave a presentation at one of Robert’s old Value Electronics shootouts in the past (live streamed) and kept mentioning how he loved D-Kuros and how many D-Kuros he personally owned. What’s the fine guy up to these days, is he still active?

Anyway, give me a few moments to find a reference link in order to fully reply to your post.

Frame by frame dynamic metadata is a relatively unused feature of Dolby Vision. That said, is has been utilized for deliverables. Ask ‘em – http://www.kmppost.com/#/work

As to ICtCp and my interest (the ITU in particular), a high performing standardized method of evaluating color fidelity is critical to evaluation of systems and equipment in this new age of WCG/HDR and the initiative is endorsed by many, e.g. http://nabanet.com/wp-content/upload...-0300MSW-E.pdf .

A color difference based upon the ICtCp signal format I’d say most in the international standards community feel is the best scheme.

D-Nice is still very active and I follow him in the OLED calibration threads. Thanks for your reply and links.

I see he is active (over at AVS at least)…. http://www.avsforum.com/forum/465-hi...l#post56305128

Too funny , what with the PLETHORA of people all over the internet linking that HDTVtest video and using it as a gold standard by well respected calibrator Vincent, here we see well respected calibrator D-Nice completely disagreeing with the material/method root basis of the comparison……and crickets as to a reply by the masses.

Robert Z., it’s up to you to employ well respected calibrator Tyler P. or David Mackenzie (if he’s learned to pronounce ‘temporal’ correctly ) to be the ultimate arbitrator of these divergent assertions.

Can HLG do ICtCp????

That may be the 64 billion dollar question in the long run.

Thank you, Tyler Pruitt and David Mackenzie will be co-staring (along w/several other video experts) at our 2018 TV Shootout.

So who to listen to, Vincent or D-Nice?

Excellent question.

I'll take a stab at it and say from what I know ICtCp is limited to HDR that follow the PQ curve and can go beyond the HLG 1,000 nit peak luminance tone mapping.

Lately, that sort of thing seems to be a common conundrum recently, because for instance I, being an Oppo 203 player and cat owner (as an aside, a cat that’s curious to play with all sorts of strings, like the dvhe.stn.uhd30 string), just a couple days back I travelled to the Oppo 203 thread as directed by my friend gkolb - https://forum.blu-ray.com/showthread...g#post15140263

and I red that well respected reporter John Archer claimed that according to his Oppo source, the Dolby Vision update was set to roll out in a day or two….. then, several posts later on the next page in clarification of his chicken metaphor, well respected Beta Tester JohnAV in response (a post which has since been deleted) was being totally dismissive of the Forbes news, implying it was incorrect.

What’s a man to do?
