I had to look it up. I won't post a link here but the file appears to be 38.06 GiB!
Interestingly, that's less than a 50GB Blu-Ray, so tell me, why did we need a different disc format for UHD Blu-Ray?

> Pirates try to justify their thefts in economic terms but at the end of the day they are no different than someone taking socks from Walmart. I agree that people just want free stuff, but stealing a physical object deprives someone of that object. Copying media is strictly a violation of a business model. There is minimal (if any) marginal cost to the owner. Better analogies include sneaking into a (not full) movie…
To the contrary the analogy is apt because when one takes the socks you are not harming the next consumer (sure the cost of shrinkage is passed on) and there are lots of places to get socks. But the party that is well and truly fucked the most is the producer of the socks who will derive no benefit from work spent, designing, promoting, producing or delivering the socks. Your literal minded response suggests that, a…

Presumably the studio sends a master to Okko and then Okko transcodes it into various formats for streaming. Imagine an insider sets the transcoder to output 4K H.264 and then leaks the resulting file. It sounds like encryption won't help here.
They wouldn't send a DCP stream for transcoding. DCP stream can only be decoded by the media block inside the projector and the output physically goes to the projector chip. The system has safe guards against physical intrusion. If you open the projector, it wipes all the keys. The level of paranoia in that thing is insane. They keys only get programmed by the studios at manufacture time, and there is no servicing of…
What if it has no power?

The point of DRM is to make that time, motivation, and quality equation not make sense. Every day that a new videogame stays off Piratebay is an extra day of full revenue. I'm not defending DRM, but it's important to know one's enemy.
Is that true, though? I'd expect that the people who only download cracked games will wait for the game to be cracked and up for download, no matter how long that takes. The people who download games to trial them and then buy the ones they like will likewise wait until they can give it a shot before potentially wasting money. The last group, those who buy legit copies of games at or near release, are going to buy it…
To clarify for all the other non HD-video nerds, this seems to be regarding DCP: https://en.wikipedia.org/wiki/Digital_Cinema_Package not HDCP: https://en.wikipedia.org/wiki/High-bandwidth_Digital_Content...

The use of DCP seems to be limited to very high resolution releases. The DCP is just a digital print (what movie theaters play for digital releases instead of the reels of film that go with analog releases). It's not really about resolution per se, it's just a term for the whole package that the theater gets.
This all works due to proprietary hardware - the modifications to the 4k cinema projectors that enable decryption almost at the lens/imaging chip can cost as much as the projector itself, doubling the price of the projector (last I heard from around 15k to 30k USD).
With a more sane key distribution (no master keys in equipment, like with dvds) - I don't believe DCP is likely to be cracked in the same sense CSS was: probably the more likely scenario is that some insider leak some of the distributors private keys which would allow certain releases to be cracked - but would likely also trigger key roll over.
Also worth nothing that the DCP format is pretty nice, has optional encryption - and you can make your own. With the right contacts you can view your own footage on on a cinema screen :-)

From what I recall, the security module has it's own battery backup, intrusion detection, etc. If the module detects tampering or it's battery goes flat, the keys are wiped.
There was some talk about that you can't keep "spare" security modules hanging around, they need to be installed in a projector periodically to recharge the onboard battery.

And exactly the time and motivation needed is why DRM can work in the end. Modern DRM schemes like AACS employ methods to change keys for new works. So when crackers find a key that allows them to circumvent the DRM scheme they can't publish it or it would soon get useless and they would have to do the work to extract a key again. This is probably what we're seeing here.
This means that for consumers the DRM stays effective. They can't do copies of things they legally bought.
The "economics" here are interesting. One of the sources attributes the piracy to a "market failure". This is not accurate. As price falls to zero and supply is infinite (piracy) there is nothing to restrain demand. Sure I want all those Tarantino special cuts if they don't cost me anything. Got Tarkovsky in 4K? I'll take that too. Pirates try to justify their thefts in economic terms but at the end of the day they a…

That's it right there. Music piracy took a long time to sort out because it was inaccessible. Now through Spotify/Apple Music/Youtube I struggle to find anyone who pirates music in my peers (it was prolific). It's not perfect yet and I think there's still some change to come but it's certainly ahead of the film industry.

I find it amusing that after all these decades people are still willing to claim some sort of moral high ground in defense of their desire for entertainment.
In the end, copyright is based on laws created by governements as trade agreements, rarely involving the voting public when it's not a dictator or monarch making the rules. In effect copyright is a matter of law, not moral, and sometimed the law is not moral. In this case, I stay my judgement as it can only cloud the real issues.
Personally I think everybody who is not an adult, without a job or a home should by default be allowed free access to anything we call culture. Being part of society is - which everyone should be - is down to having a shared context. The so called entertainment is a major part of this, and without access to it you become an 'other', the outsider.
Moral or not.
