The Galaxy Note 7 and its Gear VR headset are a right step towards personal virtual giant screen movie theater, but at least 4K screen phone is required for a comfortable HD viewing.

The Fourth Phase is the first sports film to be mastered in Dolby Vision and Dolby Atmos……

On a side note to locals….the Dolby Cinema installation at the AMC Orange (across the street from UCI Med Ctr. as I previously posted) remains on schedule.

Deploying Wide Color Gamut and High Dynamic Range in HD and UHD

Charles Poynton, Jeroen Stessen, Rutger Nijland

This is an extended version of the paper with the same title that has been presented at IBC 2014.1Twenty years ago, Poynton presented a paper at IBC 1994 entitled “Wide gamut device-independent color image interchange.” The CCIR 709 standard had just been adopted (in 1990), and, by 1994, sRGB deployment in desktop computing was well under way. That paper anticipated commercial interest in exchange for wide-gamut imagery. As it turned out, wide gamut was not imminent: We’ve had 20 years of very stable color encoding for video in the form of BT.709 for HD (augmented recently by BT.1886, which finally standardizes gamma), and the 709-derivative sRGB that remains ubiquitous in the computer domain. Now, however, dramatic changes are under way. Wide color gamut (WCG), enabled mainly by RGB LED backlights for liquid crystal display (LCD) displays, has already seen initial deployment in consumer television. High dynamic range (HDR) cameras are commercially available; and HDR displays, mainly enabled by spatially modulated LED backlights, are on the verge of commercialization. Many industry experts agree that consumers will experience WCG and HDR as more significant than increasing spatial resolution from HD (“2K”) to “4K.” This paper revisits the topic of the 1994 paper, but now with some urgency, to address the question: How should wide color gamut and high dynamic range video imagery be encoded? The main conclusion is that the Y’CBCR technique and its variants are perfectly adequate for moderate dynamic range, but yield less than optimum performance when combined with HDR. New encoding techniques are needed. We conclude that: ▪A new high dynamic range opto-electronic conversion function (HDR OECF) (perceptual quantizer) should replace the conventional gamma function to enable HDR. ▪HDR should be encoded with at least 10 bits per component, to suppress “banding.” 10 bits Yȁ- ;CBCR 4:2:0 is at this moment the accepted standard for encoding HDR, and Philips will support the developments deriving from that choice. ▪Going to 12 bits Y”CBCR 4:2:0 will bring too little perceived improvement on natural content; further improvement must come from other changes. ▪CBCR (chroma) subsampling performs worse in combination with the HDR OECF; we propose encoding and decoding constant luminance, with modified u'v' chromaticity components instead of CBCR. ▪Therefore, for the future, we propose going to 10 bits Y”u”v” 4:2:0.

Special note as to the recipient of the Progress Medal which is the most prestigious SMPTE award and recognizes outstanding technical contributions to the progress of engineering phases of the motion picture, television, or motion-imaging industries….going to Douglas Trumbull.

I hope his continuing project proves fruitful as I enjoy having options. Any Silicon Valley investment groups interested in funding Magi Pod installations?

Aw man, Penton. I'm already really excited to see Kubo and the Two Strings tonight. This is exacerbating my annoyance that I do not live near a Dolby Cinema. Luckily, we are on the list to get one, hopefully soon. But I don't think soon enough to see Kubo in Dolby Vision.

Prior to the time any other websites were accurately discussing it, I remember some of our earliest discussions in 2015 here on Blu-ray.com as to whether HDR would enhance Animation imagery in which Adrian asked a good question before Inside Out opened…https://forum.blu-ray.com/showthread...r#post10865373

History has proven that ^ prediction correct. In short, simplistic terms, animated movies have the potential to be the sweetest eye candy of the HDR frontier.

I know Inside Out was the first movie to break out of P3 and into full 2020. I would love to see that. Have you heard of any others going beyond P3 yet? If any, I would assume it would be animation.

[Penton-Man]

^ I expect more animated films to explore the frontier of maximum Dolby Cinema luminance in thee aspects of some of their scenes to aid in the storytelling effect.

Although, note…Ultra HD Blu-ray only deals in the non-constant luminance format which is also considered the default by ITU for HDR.

It was incredibly beautiful in more ways than one! And I only saw it in SDR. I can't wait to be able to see it in HDR.

Since by my handing out above accolades specifically to Douglas T. and Charles et al., I should also give a tip of the hat to someone else we’ve referred to in the past here on Blu-ray.com, namely Thomas -

HDR10 vs. Dolby Vision: The new TV format war

...Does that mean Dolby Vision is superior to HDR10? Not exactly. While Dolby's colorists and mastering engineers do, in fact, have a larger artist's palette to work with (given their higher mastering targets compared to HDR10), it's definitely a movie-to-movie basis.

Paul , that title ^ sounds rather provocative. Without reading the entire article, I hope the author(s) realize that in the grand scheme of things, the HDR parameter and how it is used, deployed, etc. is still in its infancy stage. Many things even at the standardization level could be improved upon, e.g. provide a clear definition of the reference level for diffuse white for HDR

[Penton-Man]

And HFR (100/120 Hz)
In the below quote, are thee SAMVIQ (ITU-R BT. 1788) subjective testing method results tallied from 31 observers (pre-screened for normal vision)

This is why next gen leaders like the EBU are also doing HDR and HFR demos at an upcoming professional conference, namely IBC 2016, top bullet point demo -> https://tech.ebu.ch/events/2016/ibc-2016

But it’s coming, e.g. those providers who are already able to manage 4K at traditional broadcast frame rate on the production side, their interfaces can be ready to do HD (rez) HFR without problem as to the data load.

Let’s wait for the Dolby Vision capable Ultra HD Blu-ray player launch in 2017 to see what the bloggers write then.

I just saw this article from the Washington Post raving about the Dolby Cinema presentation of Kubo and the Two Strings:
