HDR Discussion Thread

[Geoff D]

Sony TV's have had internal processing at 14-bit for quite some time IIRC (and their Blu-ray players have a 14-bit option too, I know the S790 did anyway) it's only recently that they've added the processing horsepower to apply things like Super Bit Mapping and their excellent Smooth Gradation feature to 4K signals.

That said, I'm already very impressed with how my 2014 Sony TV handles the 12-bit 4:2:2 2020 signal coming out of my Panasonic player.

Dolby Vision being 12-bit but no 12-bit panels existing yet is just another example of how in flux this all is. No matter what you buy today it's outdated next CES.

yes pretty ridiculous as dolby vision is native 12 bit yet no 12 bit panels announced this year

i read it works very well with 10 bit so its all good

best to follow the Blu-ray.com threads (moments ago I just edited out the eye catching Marilyn Monroe YouTube clip in that old 2014 post, so as not to distract from the major technical point, being....

when ST 2084 (the PQ HDR EOTF) arrived on public scene and who (meaning us at Blu-ray.com) was waiting for it),

rather than Johnny-come-lately reporters/bloggers posing as longtime experts on whatever advanced video topic. I also expect the detail specific postings in this thread and the 4K Movies Releases thread describing HFR testing and proof of concept to precede the internet discourse herd if not by months, then over a year.

Shows it’s an advantage to consult in person with people in the know.

With regards to completing the entire ST 2094 document suite (what hobbyists essentially know as the dynamic metadata suite), although not mentioned in the latest progress note update here -> https://kws.smpte.org/kws/public/pro...project_id=294 , thee Encoding and MXF Mapping document of the ST 2094 document suite proceeded into the Draft Publication status (Audit then actual publication) at last month’s meeting.

For those who celebrated a little too robustly on New Year’s Eve and lost some neurons in the process , reminder from Jan. 2 - https://forum.blu-ray.com/showthread...h#post13057638 , mark your calendars accordingly for the Jan. 19th HLG discussion.

I’m hosting a Golden Globes ( http://www.nytimes.com/2016/12/12/mo...e=article&_r=5) watching party soon where I’ll probably lose more (neurons).

It looks like Advanced HDR, SL-HDR1, and Technicolor HDR are the same HDR format. Advanced HDR can either use automated HDR/WCG upconversion on a SDR video signal or use proprietary metadata to add HDR/WCG to a SDR video signal. Personally I am skeptical that a small amount of proprietary metadata can change a SDR video signal into a HDR video signal. It is one thing to reduce the amount of information you have in a video signal (resolution, color space, dynamic range, etc...) but another thing to increase the amount of information.

That does help explain the business appeal of it since it ensures that the SDR video signal will reach the consumer.

[Zhorik]

Is there any way to find out TV gamut volume with and without HDR or gamut area at different luminance values?

LG OLED TV will support all major HDR formats.

Apparently, all 2017 LG OLED TV will be compatible with HEVC HDR10, HEVC Dolby Vision, HEVC HLG HDR, VP9-HLG YouTube HDR, VP9-PQ YouTube HDR and Technicolor HDR.

At the end of the day, it is content that matters most, not content format.
A consumer-driven HDR TV shall be able to play any HDR content.

So far, Life's Good!

[Robert Zohn]

Thanks ^^ for confirming and happy to see LG included all possible HDR formats.

Advanced HDR format is a group proposal from Philips and Technicolor but it only supports some of the features from the Philips proposal. The original Philips proposal did allow for the encoding of a HDR video signal. Advanced HDR is EOTF agnostic because it always uses a SDR video signal.

My bad! I used the unrelated figure of the Philips white paper.

The right one:

Last night I had a dream; that exact same dream.

To be fair I think that Philips/Technicolor has just as good of a reason to make a HDR format as Dolby. The problem is that the increasing number of proprietary HDR formats is better for companies than consumers. It is like a race where as fast as you run towards the goal the goal runs away from you. HDR needs a fixed goal in order to be completed.

Not noted above ^, but planned, is for the Charles P. (to whom the Peter C. is addressing within the first minute or so of this presentation -> https://forum.blu-ray.com/showthread...e#post12883491 ) to speak about HDR and WCG.

Be there, or be square…he’s top drawer.
