4K Blu-ray Confirmed, Coming in

[bailey1987]

According to advanced television.com the bda has finalised the HDR technology that will be used apparently there going for all three.

The Blu-ray Disc Association (BDA) has agreed a batch of standards for ‘next generation’ Ultra-HD Blu-ray discs. The news, reported by trade magazine Large Display Monitor, says that the BDA will support three High Dynamic Range (HDR) technologies, including Dolby Vision, and the HDR on offer from Philips and a joint-suggestion from Technicolor that’s part of the MPEG/SMPTE proposals.

Didn't want to piss any one member on the BDA off, so now the TV's will have to support all of them. According to Joe Kane the HDR proposals were not created equally.

Now that's just great. A format war reminiscent of DTS-HD-MA vs Dolby TRUEHD.

What's the worst that could happen? What's the maximum number of nits we can look forward to? I can remember reading a Dolby Vision article I'm sure it said 10,000 nit brightness. Anyone know for sure.

I'm guessing by this that TV' will only be able to support one of the three.

The link http://advanced-television.com/2015/...andard-agreed/

Maybe displays capable of showing all three with decoders that handle the 3 formats with an option to switch among the three or like your AVR automatically switching between DTS-HD-MA, TRUEHD, etc ?

Does anyone know if Large Display Monitor trade magazine has a web page?

Exactly why hdr will not effect my 4k set purchase

There will probably be a lot of receivers/TV's with support for all three later. Or firmware updates to allow them. This is somewhat strange sounding, though.

When I do get a 4K HDTV I am not really sure what would be best given some of these issues. I guess this is another good reason to wait for the full retail specs to be available and actual product for people to check out. Hopefully almost all HDTV's will have full support.

b.t.w., bailey, since you made that post, I’ve noticed today that there has already been at least one editing (without public notification of such) of that original article from advanced-television.com. in regards to the nature of the HDR offerings.

However, it’s still in need of further editing further on down the piece in order to be accurate. On the other hand, what else is new in the world of A/V reporting .

So what's the edit?

i hope they will put real 24fps and not 23,976fps on future uhd-bd releases. any chance this will happen? this is an outdated standard and practice.

Original version, shortly after published is posted at the top of the page by bailey and, for that matter, a little earlier by the satellite guys - http://www.satelliteguys.us/xen/thre...agreed.347353/

Which I wouldn’t be surprised, knowing the internet, other A/V sites simply copied and pasted the original version to their *breaking news* sections and the clueless masses accepted everything as gospel.

Revision …”players will support an open standard High Dynamic Range (HDR) technology, using 10 bit HEVC MPEG video encoding and based on SMPTE HDR signalling. The format will allow for optional layered solutions including Dolby Vision, and the HDR on offer from Philips.
However, a 4K proposal from Technicolor was not set into the new proposals.” http://advanced-television.com/2015/...andard-agreed/

As to what else remains inaccurate, well, for one thing, the author should investigate who all the members were (and what organizations they represented) in Study Group 6 and Working Party 6C with regards to his “EBU’s Recommendation 2020”.

24 fps is in the proposed frame rate standards. The DCI-P3 graded cinema masters from whence the UHD disc versions will probably be sourced from are 24 fps and not 23.976.

Some Blu-ray's are in 'real' 24fps. But yes, the majority are 23.976fps.

Most of the current (2014-2015) productions I've seen using digital cameras capture at 23.976 so I doubt that's going away any time soon. So I don't see what's outdated.

[hajiketobu]

I find the anything but the use of full-frame frame rates problematic for 2015 and beyond. It's an old standard from the times of tube tv
s, of course it's outdated. And it can cause problems too! Plus it's an unneeded nuisance to adjust 24fps to 23,976fps back and forth during mastering.

The only reason this still exists imo, is for old NTSC tube TV's to ensure playblack. And for TV shows and productions of course, which are also shown on tube tvs.
But let's be honest, everyone who will buy a movie on UHD-BD will have an UHD- or HDTV and non tube TV's are not exactly a fan of framerates like 23,976 or 59,94!

I think this should have already been done in times of the Blu-Ray, but I can understand that it was a time of change and transition to the new equipment, so it's okay. But I don't see any reason to keep this going. Same goes for HFR; full 60fps, not 59,94!

Probably a typo, but just for the record in case new members are reading….it’s SMPTE and there are student chapters (Baylor U., etc.) for those young turks out there having interest but not quite yet the technical wherewithal to serve on Standards Study Groups…https://www.smpte.org/membership/student/chapters . Also for new readers, it’s pronounced Sim-TEE….

^ Postscript. The 60-day crowdfunding campaign for the MOVING IMAGES documentary raised a total of $66,382 before ending.

As an aside, when I’m alerted to outside links sent by other members via PM, I am amused by the Monday morning armchair quarterbacks from outside websites and home theater/movie forums who’ve suddenly (since CES 2015) become pontificating experts on ST 2084/2086 as it relates to color gamut and dynamic range of Ultra HD Blu-ray when they had no freakin idea of what projects we were discussing here in the Tech Forum of Blu-ray.com back in Dec. of 2013…
