Default 4k BD Disc Specs

Hey guys,

Reading around, I learned that there aren't currently any computer programs that can play 4k Blu-rays.

But my drive won't even *read* them, the disc spins and eventually it acts as if there's no disc in the drive.

Do 4k discs use BDXL? Or is it some odd form of DRM where the computer will just act as if there's no disc in the drive (sorta like PS3 and Wii U discs)?

I wasn't expecting to be able to play them yet, but I just picked up a 4k copy of The Revenant and was interested in seeing how big the disc was. The 1080p disc is a whole 43GB, just barely under the size limit!

My drives only read dual layer, not BDXL, which is why I'm wondering.

43gb is not almost whole disc, 49.4gb is max

Is it? I thought Blu-rays, like any other type of storage, used "salesman's bytes"

Which would mean 50GB is more like 46.6GB in actual computer (base 1024) gigabytes.

Or when they say 50GB for dual layer, do they actually mean 50GB as measured by a computer?

Now that I think of it, optical media seems to be a mixed bag... CDs said 700MB and they actually held 700MB (though in reality they could hold more like 800 and the 700 was just a conservative estimate), but on the other hand DVD said 4.7GB where it was actually ~4.35GB due to the 1000/1024 effect.

4K Blu Ray uses 66 gig and 100 gig disks.

Ah, OK. So they're basically BDXLs? If I get a BDXL-reading drive, would I be able to at least see the disc contents (even if encrypted)?

I said 4k, not 3D. I can read 3D discs just fine.

You might want to update your original post then to say what you thought you said.

BDXL is a write technology. The 4K Ultra HD Blu-ray discs are not BDXL discs, but instead stamped in a optical factory.

My BDXL Blu-ray drive does not work with 4K Ultra HD Blu-ray discs. Some computer manufactory needs to come out with a certified 4K Ultra HD BD-ROM drive that reads the 4K discs.


This entire issue is a big mess with no software or hardware to play the new 4K discs on a dektop or Laptop computer.

It might be because of two things, first the industry doesn't want a rehash of BD ripping and stripping HDCP that typically happens with HTPC's. Second it might not be cheap enough/marketable to make for the PC community. Everything UHD is so dedicated (separates), when you can get a Nvidia Shield for not much, why would you want this built in to a PC?

Also note this not really the right forum for this question OP. There is a Ultra HD Blu-ray and 4K forum here.

If the consumer electronics industry and the movie studios decide that they do not want computers and future videogame systems like the PlayStation 5 or XBOX 3 playing 4K Ultra HD Blu-ray discs, then this will be a very small niche market. 3-D Blu-ray discs are more popular then 4K Ultra HD Blu-ray discs. At least consumers can play 3-D Blu-ray discs on the Playstation 4 and windows based computers.

HDCP 2.2 and other advanced encryption security are keeping the 4K Ultra HD Blu-ray discs 100% secure from pirates attempting to copy the discs. I have not read stories about the new encryption technology being broken by hackers JohnAV.

There is only one standalone Blu-ray player on the market that can play these 4K Ultra HD Blu-ray discs. Possible late 2016 Panasonic, Sony, and OPPO might join Samsung with a launch of a native 4K Ultra HD Blu-ray player.

In regards to price, the first generation Samsung 4K Ultra HD Blu-ray player is selling for around $400. A 4K Ultra HD BD-ROM drive in theory would sell for under $100. Maybe $200 for the first generation model. PowerDVD 16 Ultra sells for around $100. We are only talking about $100-$300 to upgrade ones PC to play 4K Ultra HD Blu-ray’s if they already have the 4K graphics card and 4K monitor (that is if someone would design the hardware and software to play the discs).

The Panasonic DMP-UB900 is already available in Europe, and should be here in the states June. Philips BDP7501 is expected around May as a FYI.

Thanks for the information. Glad to hear Europe has the Panasonic model. I would be interested in the Panasonic model when it arrives in the United States around June. Sony and OPPO native 4K players most likely will be late 2016 or early 2017.

43GB is within the safe zone. Most publishers never use more than 44-ish gigs, because the error rate is much higher when you use the last five gigs on a disc.

Where did you read that? Not disputing it, because the outer edge of the disc is indeed where most of the read errors occur - just curious as to the source. Having said that, I routinely fill discs up to the brim and we've never had any reports (actually there was one, but the replicator who pressed the disc is no longer in business).

We're fortunate though in that for the European markets, almost everything is manufactured by Sony DADC and Technicolor, both of whom have exceptional manufacturing quality.

When I first started as DVD author one really small distributor had some discs manufactured in China, and my own personal copy came with a dead insect squashed between the two layers of the D9 disc. The replication got moved to Hong Kong after that.

Anime section of this site. Blu-rays have safe zones the same way DVDs did. Disc replication companies charge more if you want to use the safe zone because they get more duds.
