Next-Gen Ultra HD Blu-Ray Discs Probably Won't Be Cracked For A While (arstechnica.co.uk)
DVDFab, a software tool for ripping and decrypting DVDs and Blu-ray discs, will not be upgraded to support newer Ultra HD (4K) Blu-ray discs. Fengtao Software, which makes DVDFab, said in a statement that it "will not decrypt or circumvent AACS 2.0 in the days to come. This is in accordance with AACS-LA, (which has not made public the specifications for AACS 2.0), the Blu-ray Disc Association and the movie studios." AACS-LA is the body that develops and licenses the Blu-ray DRM system. AACS 2.0 has a 'basic' version that sounds quite similar to existing AACS, but also an 'enhanced' version of DRM that requires the playback device to download the decryption key from the internet. There might still be a hole in the AACS 2.0 crypto scheme that allows for UHD discs to be ripped, but presumably it'll be a lot tougher that its predecessors.
I still haven't left DVD, like I needy another type of crappy optical disc.
Yeah, don't use this: https://www.hdfury.com/shop/ot... combined with this: https://www.thestreamingguys.c... Now you know how not to combine a HDCP 2.2 decrypter and a capture card to not record the raw 4k stream.
Correct me if I'm wrong, but so far there have been a total of zero successful attacks against AACS (the Blu-Ray encryption system). Everything so far has been built around using known decryption keys extracted from BluRay players and playback software.
Obviously, that doesn't stop your from emulating an LVDS flat panel and taking your output from after the stage where it has been decrypted and now thinks it's talking to a flat panel display, but is instead talking to your electronics instead.
It's unlikely that a television owner will accept the equivalent of an "error 53" on their very expensive display panel, so third party repairs will most likely remain possible. At which point we can know there is no security association between the flat panel itself and the separate decode hardware stage.
So basically: if people can see it at all, it's possible to get it in cleartext, even if you may eventually have to resort to tempest-level eavesdropping on the flat panel itself.
Now while it's true that these things might be watermarked in the decode process... it's possible to use sampling with multiple sets of hardware, and then use differential analysis on the images to remove, or at least obscure, andy electronic artifacts designed to identify the source of the video. Not that it's not actually going to be the same way most movies get released these days: someone gets a hold of an awards ceremony DVD by doing dumpster diving, or some member of the academy just releases it, or the pressing factory in China just runs a "third shift operation".
Frankly, however, I can't see them being successful in requiring going to the Internet; it's not like the Internet can tell if it's a legitimate disc in the first place, if it's a bit-identical disc that was run off by the factory that ran off the legitimate copies. It's basically a repeat of the DIVX (DIgital Video eXpress) fiasco if they go that route anyway. https://en.wikipedia.org/wiki/... -- nobody wants to rent the videos they buy, and potentially later lose access to them, when you replace a player, or a key that happens to be for your brand of player gets invalidated, or the studio goes out of business, or gets bought by a religious organization that thinks R-rated movies are somehow "Against God".
And if you think that can't happen: It's Chick-fil-A's nationwide policy to be closed on Sunday because of its managements religious beliefs.
Some notes from someone in the industry...
The 'enhanced' version is not yet used, everything out so far is using the basic AACS2, it is unknown exactly when the enhanced will be available for use. Knowing how past AACS requirements have never materialized, I actually wouldn't be surprised if this never really takes off. Also Fox is really the only studio I know of that is interested in this. They are also the only one I can think of that uses BD+ regularly, and are more technically minded than other studios.
Streaming is no where near the quality of these discs. Someone posted that Netflix streams 4k at about 16Mbps, while the video on these discs will be over 100. Also the bigger aspect of video on the UHD discs is bt.2020 HDR color space, which I don't think Netflix does yet. M-go is the only place I know of that has similar quality video, Fox tries to use the same encode on the UHD BD as they do for their "Vidity" downloads on there. Also if sound is important to you, I don't think anyone streams Dolby Atmos or DTS:X audios.
