HDR Discussion Thread

[James Freeman]

Geoff let me see if understood you correctly;

Sony discs have a Primary and Secondary P3 100% Saturation at 100nit windows in a 2020 ST.2084 container right?
You measure the xyY points of these patterns with your meter and plot these in HCFR (editable data) to see if they inside the reference spots of P3 or 709?

How exactly do you plot in HCFR?

Can you be more specific about the patterns in the Sony disc (saturation, 709 P3 2020)?

[Geoff D]

I thought you were aware of the Sony patterns? They are 100 nit windows for RGBCMY for 2020, P3 and 709, all encoded with the HDR EOTF in the 2020 container. HCFR can measure all three of those colour spaces, so to check 2020 coverage I simply took readings of the 2020 primaries and secondaries with my colorimeter (which has been profiled off a spectro to my specific display) and HCFR does the rest. As I said, the resulting SDR 2020 CIE chart was extremely similar to an actual HDR 2020 reading taken by AVF for one of this year's Sonys.

Thanks Geoff.
This 2016 Sony HDR TV review right?

The windows all 100% saturation right?
Does a Sony UHD disc offer a ST.2084 greyscale tracking windows also?

Close enough, it was the 55XD9305. I posted the result of my gamut comparison here: https://www.avforums.com/threads/son...#post-23578585, the magenta is off a ways and without lower saturations I can't check whether it's being properly mapped to 2020 or not, but as I said in that post: it's a brilliant result for a 2014 TV which I thought would never have a hope in hell of displaying WCG material.

The Sony disc doesn't have greyscale windows, instead it's got a series of ramps going from 0 to 10,000 nits. (I can see down to the 0.005 pattern with the SDR conversion at standard settings, and down to the 0.010 pattern with my personal SDR conversion settings.)

good to see you took the journey (with or without Deci) as advised

[Geoff D]

Are you kidding? That was one of the first things I checked when I got my player, I was itching to know what was on there because no specifics were forthcoming.

The prize is greater, the more difficult the journey.....just posted something in Prem thread you may be interested in.

100% of 4K Ultra HD Blu-ray discs that use HDR only use the HDR10 format. So all 4K Ultra HD Blu-ray players have HDR10. Dolby Vision is only needed if one is interested in getting HDR from 4K VUDU and 4K Netflix streaming.

Therefore it would be ideal for all future 4K Ultra HD Blu-ray players to include Dolby Vision so that consumers can stream 4K Ultra HD movies from Netflix and VUDU with HDR. It sounds like no HDR for streaming from any Blu-ray player that has been released so far. Some consumers own 4K projectors and they need an external device to provide 4K streaming (Sony makes 4K projectors and in theory they might release a 4K Ultra HD Blu-ray player in the future that offers Dolby Vision technology).

“There are two prominent (but not identical) high dynamic range formats now used commercially, Dolby Vision and HDR10. The Samsung player supports only HDR10, the format used in all of the first HDR-enhanced UHD discs. The UBD-K8500 will also play standard Blu-rays, DVDs,and CDs.”

So is the Samsung now supporting Dolby Vision with a firmware update or is Amazon sending HDR using HDR10 technology?

The K8500 only supports static HDR10 as of right now. amazon currently only supports HDR10 but will support dolby vision soon (as they announced). the k8500 will not support dolby vision at any point.

[HDTV1080P]

It looks like some titles from Amazon streaming are HDR10 and some are Dolby Vision.This would mean that only the HDR10 titles from Amazon will playback on the first generation Samsung 4K Ultra HD Blu-ray player.

“Amazon has not confirmed which titles will be available in Dolby Vision. It currently offers Transparent, Mozart in the Jungle, Bosch,The Man in the High Castle, and Red Oaks in HDR10. Future TV series and movies will also be produced in HDR.

If we really are going to start seeing Dolby Vision 4K Ultra HD Blu-ray discs released, then those titles will only playback at 3840 x 2160P with no HDR on the first generation of 4K Ultra HD Blu-ray players.

I am interested in the Panasonic 4K Ultra HD Blu-ray player when it is released in the United States. However I might wait for OPPO or Sony to release a player that supports both Dolby Vision and HDR10.

[HDTV1080P]

Hopefully all second generation 4K Ultra HD Blu-ray players will support both HDR10 and Dolby Vision, especially if Dolby Vision Blu-ray discs are released. Also the display is going to need to support both versions of HDR.

HDR10 as a baselayer is required for all DV discs.

Some 4K Ultra HD Blu-ray discs do not have any HDR at all. Are you saying that any Dolby Vision encoded Blu-ray disc will also be encoded with HDR10 as a base layer?

I'd say that a majority of films on UHD Blu-ray will have some sort of HDR grading since that's a selling point of the format.

12 bit Dolby Vision has an HDR10 (10 bit HDR) core as a requirement for UHD Blu-ray's that may happen to include it. So, any UHD Blu-ray player will give you some sort of HDR output no matter what.
