And a YIFY 1080p release is less than a 4.5GB DVD, why did we need a different disc format for regular Blu-Ray? A VCD release fits on a 700MB CD, why did we need a different disc format for DVD? You can make video files come out any size you like - even 1 MB - if you're willing to make the tradeoffs (on both quality and time-to-encode dimensions). There's also a limited amount of hardware you can put into a set-top p…

You could still sell the set-top player (which aren't really at a "low" price point) with H.265 as the codec on the current-gen Blu-Ray disc - reducing manufacturing costs.

Normally those kind of decisions are optimized by free market competition. It doesn't seem to have kicked-in in this case, probably due to the elephants in the room (piracy and streaming) having zero capex cost.

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... (which is already broken, and was itself the industry response to the breaking of DVD CSS: https://en.wikipedia.org/wiki/Content_Scramble_System ). The use of DCP seems to be limited to very high resolution relea…

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.

I agree in principle, but I think the adage that "Every day that a new videogame stays off Piratebay is an extra day of full revenue" is a bit of a false equivalency.

All I know is that the music industry learned a long time ago DRM didn't work and wasn't worth it, and I can now buy MP3 files on any service, and play them on any device. And while I don't engage in movie piracy myself, I hope these pirates are successful in driving studios to that same point, where I can happily shell over $30 for a 4K file and use it how I want to.

There's a difference though. DRM music files are sold directly to consumers. These consumers have to be able to decrypt the files on their own computers / devices which makes DRM useless. The movie files in this case are not meant for consumers. They're only decrypted on specialised equipment not accessible to the general public. If you manage to get your hands on a DCP file there's nothing you can do to decrypt it w…

Yeah, but let's be honest, if I had a job as a manager at a theater and a moderate amount of reverse engineering skill or a small team of friends with those, well, time, access and tools combine quite well...

Sure, they make it look all secure, pass it through all that crypto and stuff but ultimately it has to be passed to the projector chip in some form which is unencumbered to be turned into light. At which point it's fairly trivial to dump. Anti-tampers on the case are probably fairly limited.

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…

> 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 product with a low incremental cost is a valid measure of of the total cost of production, which it is not. The cost is writers, actors, foley artists, costumers, grips etc. All of whom lose money when someone decides it's okay to steal a copy. That is a thief who will never pay a legitimate fee for what they have taken.

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…

Insane, the levels we'll go to in order to secure content from hitting someone's eyeballs and ears before ensuring money changed hands in the vague direction of the content creators at some point.

Interestingly, that's less than a 50GB Blu-Ray, so tell me, why did we need a different disc format for UHD Blu-Ray?

Because Hollywood has higher quality standards than pirates?

Tell that to the pirate encoders who had to deband movies because the official releases were so bad.

When you say "projector," do you mean a projector like in a movie theater (shooting rays of light out at a screen, etc.) or something else?

Wow. That's truly insane.

However I guess anyone who values something so much would also go to great lengths to protect it.

Still... wow. I mean, how much does it cost to design and implement that system alone? tens of millions of usd at least?
