Dolby Vision 4K BD discs expected 1st half 2017, players later in the year.

David Katzmaier ‏@dkatzmaier 1h1 hour ago
Giles Baker, SVP @dolby told me Dolby Vision 4K BD discs expected 1st half 2017, players later in the year. Also:


David Katzmaier ‏@dkatzmaier 1h1 hour ago
@web hamm @dolby @linked In Yes, the discs will come before the players. DV discs will also support HDR10, as required by 4K BD spec.


David Katzmaier ‏@dkatzmaier 1h1 hour ago
Baker @dolby also says royalty cost on a DV TV is less than $3 per set, and that hardware cost is “minimal.” Seems right given Vizio’s low $

They are gonna have to bring it next year, since HDR10 is supposed to be updating with dynamic meta-data and other stuff, which will render DV moot. Just another reason to hold off buying any 4K stuff for some time.

Won't the TV have to be Dolby Vision compatible for the DV-enabled UHD Blu-Ray player to work?

The players will do HDR10 and DV. HDR10 is already built-in while DV is add-on. The real question is whether or not any DV players in 2017 will be/can be software updated to bring dynamic meta-data to HDR10. The industry is very hush-hush about what bringing dynamic meta-data will entail. Some display makers have simply said "firmware update" for their TVs, but nobody has spoken about the actual update for players, other than to say "it could happen with firmware updates" if the chipset is programmable enough to do so.

How will dynamic metadata render Dolby Vision moot? Doesn't Dolby Vision add a 1080p layer on top of the HDR10 UHD layer bringing it sort of to 12 bit (apart from the fact the new layer is only 1080p)? How will HDR10 be equivalent to Dolby Vision (for those who want Dolby Vision)?

I'm curious to see whether Chicago and Die Hard will be among the first titles. These are two films Dolby had already remastered in Dolby Vision a while back.

So from my understanding, the disc will have the regular HDR10 movie and the DV add-on meta data. If this is true, that is awesome!

Yes, the UHD BD spec requires an HDR10 base layer when DV is present.

Or they could just increase the video compression. Also the Dolby Vision layer is only 1080p so shouldn't need that much bitrate (not as much as if it was "4K"). Actually I wonder if people have or will notice the lower resolution of the Dolby Vision layer (eg. a starfield or other things where pixel accuracy is important and the DV layer not aligning the brightest portion of the picture accurately because it's just 1080p).

It is for the UHD BD format, where are you getting 1080p from?

One place: From the Blu-ray+UHD Blu-ray specs dated August 2015 (paper actually says July 2015) (part 3, v3, white paper). Talking about Dolby Vision (on page 17), it says: "Enhancement layer video stream: 1920x1080 resolution,".

edit: Here's a link. See page 17 (Dolby Vision section):

Interesting... I'm curious as to how that works. So the resolution of the content in HDR10 is 4k but the overlay or DV layer is 1080p?

This SMPTE paper says, "The Dolby Vision enhancement layer increases the bitrate by only ~20-25% above the backwards-compatible base layer."

Yes, it seems to be (eg. based on the UHD Blu-ray specs) that the Dolby Vision enhancement layer is 1080p. I don't know exactly how it works. You could look at the following link:
https://www.dolby.com/us/en/technolo...hite-paper.pdf

eg. the table on page 11 in the link above might help too (though it's not specific to UHD Blu-ray). But in that diagram it seems to get split into a base layer (full res) and an enhancement layer (quarter res).

I'd like to see more info too though. Maybe the bandwidth for a full res enhancement layer would just be too much (and cause the rest to be overcompressed and give too little noticeable improvement?. eg. if it increased the required bandwidth too much the PQ on UHD BD for non-dolby vision capable TVs could probably get lowered too much? Perhaps Dolby think in real world content you wouldn't notice much difference between a full res enhancement layer vs a quarter res one most of the time?).

I think you are taking it too literally. That would mean two streams on one UHD disc which is hardly efficient.

How else can non-Dolby Vision compliant equipment play/show the HDR10 part of UHD Blu-rays that have Dolby Vision HDR?
It's meant so that those capable of just HDR10 can just interpret the HDR10 part and display that on a HDR10 compatible display (or the HDR10 compatible player can convert it to SDR for those displays),
or if the TV and player are capable of Dolby Vision, it decodes the HDR10 and the (1080p) Dolby Vision enhancement layer.

Dolby Vision can use one or two layers (I suppose it's like two streams?) - and yes the two layer version is less efficient but more compatible. But the UHD Blu-ray version uses the two layer version (and this way content creators etc. aren't forced to use the Dolby Vision version, they can still use the standard 10 bit HDR. DV is optional, but UHD BD players have to be able to play back the HDR10 default HDR standard - if encoded on the disc.

HDR10=mandatory for UHD BD discs that use HDR
Dolby Vision, on UHD BD=an optional enhancement layer (1080p) that takes it to 12 bit (or at least that's what is claimed - how it exactly works if the base layer is the HDR10 (uhd) but the enhancement is only 1080p doesn't really add up).

I would've thought at CES 2017 maybe a few Dolby Vision titles would pop up somewhere in the coverage, but I've seen nothing. Its like Dolby could care less about their own product. Or more likely they have nothing to show because its still vaporware.:roll eyes:

I'm beginning to think "early 2017" is not gonna happen for Dolby Vision titles to show up on store shelves..

The studios announce their own titles. It's not Dolby's announcement to make. Dolby would announce licensing/use of the technology, which they did.

More info is coming...when the time is right.

Dolby Vision and Atmos are big in Asian films, so I'm sure they are getting it earlier/more on UHD-BD than we will.

If one of those 3 studios is Lionsgate I will be EXTREMELY happy. I just hope more studios will get on the DV wagon at some point later this year.

Bill Hunt, from thedigitalbits.com, commented on this during CES week:

"In terms of Dolby Vision, the format did get a boost today in an announcement from Warner, Universal, and Lionsgate, which all committed to adding Dolby Vision HDR to their forthcoming 4K Ultra HD Blu-ray titles. So that’s something. (They should start arriving in stores in late Spring or early Summer)."

HEVC UHD at 24p is not that hard to decode in real time these days, mobile phones can do it easily. They can even do almost 4K x 2K at 60 fps, in stereo (for VR), in other words 4K x 4K (roughly, in practice it's slightly less). I'm 100% sure they could also decode a 1080p stream alongside a 2160p24 in terms of bandwidth, although the interfaces aren't the same. The DV decoder chips probably just added another 1080p HEVC decoder chip in parallel though, those should be dirt cheap these days. As you say, for efficiency (no stream swapping every frame).

In theory to bring up from 10-bit to 12-bit all you need is 2 extra bits per channel, so even if you cut the resolution in half you can still pack in missing pixels in from 8-bit HEVC layer which has in fact 2x as many total bits that it needs to reconstruct a full res 12-bit image. All you need is 4 bits per channel to reconstruct 12-bit 2160p from 8-bit 1080p at full res. You can split low order bytes from high order bytes then unpack it in the Dolby Vision decoding step.

Also, 1080p is not one quarter res, it's half res, but a quarter of the total pixels since it's a rectangular surface hence the ratio is squared. Meaning 1/2 horizontal * 1/2 vertical = 1/4 the amount of pixels and bandwidth.

Since 2160p is 4x the pixels as 1080p, surely you need to store 2 bits (per channel) from each 2x2 block (2 bits x 4=8 bits per channel) to store in an 8 bit 1080p enhancement layer (or above are you basically saying the same thing?).
But in terms of HEVC compression (compressing the 1080p enhancement layer) is that really more efficient than just storing the enhancement layer as a 2160p image instead of a 1080p one (eg. the HEVC compression will be based on blocks moving but in the "1080p enhancement layer really storing 2160p worth of added bits" surely it's going to be more difficult to track the motion/changes to the blocks (since the pixel in it really references 4 different actual pixels)?

Also, in theory, won't a UHD Blu-ray, if encoded like above, and mastered to allow for Dolby Vision mean the players and TVs that can only output the HDR-10 portion are likely get a worse picture (eg. more clipped highlights) than UHD-Blu-rays that were mastered just for HDR-10 (and that's ignoring the Dolby Vision using up extra bandwidth that could have otherwise been used for the HDR-10 encode).

During EDR mastering, dynamic metadata for Dolby Vision is generated to reflect the relationship between the HDR and SDR versions of each video frame. This dynamic metadata is carried in the Dolby Vision enhancement layer.

All Dolby Vision playback devices are compatible with both single-layer and dual-layer profile content. A Dolby Vision dual-layer stream with an SDR baselayer and an enhancement layer can be decoded, combining the SDR stream with the enhancement layer stream and dynamic metadata, to produce Dolby Vision HDR video, with dynamic metadata, to drive a Dolby Vision display. Or, the SDR stream can simply be decoded to produce SDR video to drive an SDR display.

A Dolby Vision dual-layer stream with an HDR10 base-layer and an enhancement layer can be decoded to produce Dolby Vision HDR video, HDR10 video, or SDR video.

In a Dolby Vision EDR decoder, the original mastered 12-bit PQ content is reconstructed by combining the 10-bit SDR or HDR10 stream, the 2-bit enhancement layer stream, and the dynamic metadata to produce 12-bit EDR video at the decoder output, with dynamic metadata. A Dolby Vision display uses the dynamic metadata, along with the display characteristics, to map the EDR video to the capabilities of each particular playback display.
