4K Blu-ray Confirmed, Coming in

The last feature on this list will be news to most, since Digital Bridge has been under wraps until today’s announcement. This feature could be described as “ripping gone legit”, the idea being that users will be able to purchase a Ultra HD Blu-ray Disc and make legal copies of the content onto portable devices – from the disc itself. Currently, studios have had success by bundling a separate “Digital Copy” DVD-ROM disc as a pack-in with flagship Blu-ray titles, but the introduction of Digital Bridge offers a more elegant solution.

How this will be facilitated, we’re not yet sure (the BDA were not available for comment at the time of going live). Perhaps the idea is that users will be able to hook their tablet, smartphone or laptop up to their UHD BD player, and the player will transcode the content onto the target device. We’re wondering how much adding encoding (rather than just decoding) features to players would up the price, but it seems like the only way of getting the job done that we can think of – doing the same via a computer would need a new UHD BD-ROM drive." [Guess he didn't know about the prospect of exporting content to a flash drive for use on mobile devices]

While it sounds like a good idea for those consumers who want to enjoy movies on a very small screen, it remains to be seen how well manufacturers, and most importantly of all, content owners, will treat this feature and its users: it’s the sort of feature that could have its usefulness squashed by Hollywood digital rights paranoia. Here’s hoping that studios won’t find ways to make it too annoying or limiting."

Rather than a reporter per se, David M. (lyris), of whom I’ve spoken to both on and offline, is known more for being a BD compressionist, author and consumer TV calibrator…the later for which I recently posed a question to him here – https://forum.blu-ray.com/showthread...d#post10794555...and reached out by offering my own information in a follow-up post below it.

I can't imagine what the backlash will be if DVD's were not allowed to be played in them. It could be another way of killing the format altogether.

Right. Given the 70/30 split in revenue DVD/BD it is a no brainer to include that compatibility. That will be up to the player manufacturers. Backward compatibility to DVD would not be covered by the BDA license, only backward compatibility to BD.

I know he is a respected calibrator. My comment wasn't meant as a criticism, just an observation. Did not know he was a BD compressionist.

I watched the video in the link you posted a couple of days ago.

No problem.

Not sure if this was covered, but a reliable source told me the UHD BD discs will be manufactured in dual layer 66gb and triple layer 99gb based on what the movie needs to encode the best quality without compression artifacts.

From business wire
Additionally, with the optional digital bridge feature, the specification enhances the value of content ownership by embracing the notion that a content purchase can enable the consumer to view their content across the range of in-home and mobile devices.

I remember that AACS managed copy was mandatory and yet it somehow never got released so I am skeptical of digital bridge which is optional. The studios may talk about it now but sadly a combination of paranoia and wanting to promote their own systems will likely doom it.

I can see it either working like BD live where if you provide the HDD it will become a digital bridge ready player, either that or the feature will be reserved for PVR type players that allow you to record live TV.

Apparently Samsung has a player ready for a release later this year from engadget

According to the association licensing is expected to start this summer, and Samsung already announced it plans to release a player later this year.

Guaranteed dead within 10 months. The UV cards are simple.

I want to know if the 'Digital Bridge' will be used as a sneaky-sneaky way of authenticating/activating the Blu-ray disc itself as this thread was talking about for awhile....or if that is confirmed gone.

Notice the BDA ain't talkin' about those "features."

We just don't know yet and there aren't that many A/V journalists willing to rock the boat and get the BDA to come clean on their DRM plans. They mostly vomit back PR release statements... just like most "regular" journalists these days.

Now that things are locked down I wonder if we will see any new logos that will be displayed on televisions, I have just been checking the digital Europe's Ultra HD logo, we knew all along that it didn't meet the minimum spec for Ultra HD Blu-ray which got me wondering when we will see the Full Ultra HD logo

More details on the Ultra HD logo here:
http://www.digitaleurope.org/Service...Technical.aspx

Can anybody remember how long it was between the HD Ready and Full HD logo's?

The current Ultra HD logo requires the following:
Video Interfaces
◾The display device accepts UHD input via HDMI. It shall support HDCP 2.2 Copy Protection.
◾ UHD capable inputs accept UHD video signals: ◾ with a resolution of 3840 x 2160 pixels
◾ at frame rates 24p / 25p / 30p / 50p / 60p
◾ with a minimum supported bit depth of 8 Bit
◾ at a chroma sub-sampling rate of 4:2:0 for 50p/60p and 4:2:2 for 24p/25p/30p
◾ with minimum supported colorimetry according to BT.709

It's mainly bit depth which needs to be changed from 8bit to 10bit and colorimetry from BT .709 to BT .2020. What's interesting is the chroma sub sampling 4:2:2 for 24p 25p and 30p but not 50p or 60p it kind of implies that we will see a jump from 4:2:0 to 4:2:2 although still the BDA have not mentioned that aspect of the specification. What do you think?

They do have some good ones to choose from over there. I would especially add this guy to the list….https://forum.blu-ray.com/showthread...d#post10662599

Dual layer HDR (e.g.Dolby Vision movie content) will require more bandwidth/capacity than single layer HDR solutions

Truer words have never been uttered. If they piss off their source(s), they lose access, or at least exclusive access to cutting-edge news, invitations to events, etc. You know the drill….I rub your back, you rub mine.

[MisterXDTV]

I'm not interested in the format as I have "small" screens but one thing that is not clear to me is this...

Is the format itself backwards compatible?

I mean if I buy the UHD Blu-ray player can I play the UHD discs on my current TV downscaled to 1080p?

I know it wouldn't make a lot of sense but I am curious about it...

Yes, absolutely. It will look like the best Blu-ray you've ever seen (barring a crappy transfer).

Plus you'll probably also see more DTS: X and Dolby Atmos immersive surround releases in UHD than 1080p Blu-ray.

From the digital bits:

The video resolution is 3840x2160, with disc capacity at 66GB (dual-layer) and 100GB (triple-layer) – at data rates of 108 mbps and 128 mbps respectively – using the HEVC codec (H.265) via HDMI 1.2 and 2.0, as well as HDCP 1.4 and 2.2. The “digital bridge” system (for Digital Copy) is optional and consists of copy features that enables local playback. What that means for each disc/player is up to the manufacturer and although the Ultra HD Blu-ray spec is complete, the BDA is waiting to hear how manufacturers will implement these features. [Read on here…]

Ultra HD Blu-ray players will be backwards compatible with existing Blu-ray media (also up to the specific manufacturers is the issue of backwards compatibility with DVD, CD, SACD, DVD-Audio, etc). The HDR component is open system (mandatory 2084/2086). As far as optional HDR, Dolby, Philips, Technicolor (etc) are working with the BDA on a certification program that ensures all HDR meets a specific performance metric. Open system HDR metadata is passed through the 2.0a port and the optional HDR metadata does not have a certain port requirement. So... there’s a little more info for you. We’ll add more as it comes in.

I forgot about VCD. Still, I wonder why DVD didn't come out sooner. I'm sure there are reasons.

10bit, wide color gamut, HDR movie content is being mastered on a smaller monitor than I’d bet what you use at home....and operators can easily appreciate the difference from traditional Blu-ray....depending of course on the principal photography.

So, finally, someone takes a shot at describing the Device Bound digital bridge option:

Not all metadata is equal.
There is static metadata and dynamic metadata (like for color transforms).
