NEW blu-ray protection

[RabidDog]

X-PROTECT blue was announced earlier this week hoping to position itself as an extra layer of copy protection solution for Blu-ray Discs, together with the existing AACS.

Its designed to prevent Illegal Piracy of the discs.. so legal piracy of the disc will still be ok?

Isn't piracy when they come and rob your ship? So this must be some sort of ship Gun-mounting system, with an added air cannon for non-lethal interdiction of said Pirates

I expect fung shao has already by-passed this... ..oooooh suits you Sir!

I am working on a new system that will make the studios very happy. You coat the BluRay discs with a film of cyanide - when any laser touches the disc, it heats it up thereby releasing cyanide gas into the room, effectively killing the alleged pirate :P :P . The only problem that I have not been able to solve is getting the discs to realize when someone is just trying to watch the movie and not copy it .


BluRay already has the best copy protection - Since I will not be buying them, I will not be copying them :P !!

While you are at it, you could design the cyanide layer so that it will only allow the disc to be played once. If someone attempts to play it a second time, the cyanide gas would be released. This way, the studios could force people to buy a new disc every time they want to watch the movie - - - uh, wait a minute; maybe they won't buy it at all! Oh well, since the studios are so snuggled up with their pals in Congress, maybe they could pass a law that requires everyone to buy a movie at least once a month. Then, if the studios get into financial trouble, they could amend the law to require a purchase every two weeks or whatever it takes to take care of the studios. That would also help the studios in another way - They would never have to produce a good movie that would sell on its own; Congress could rescue them whenever they need more money.

And after they are on the store shelves, just walk in with your powerful green laser pointer and scan the shelves.

Then run out.

All those pirates won't be following you.

I should be able to believe it but I cannot...that people still buy this junk. Not only are they making it difficult for their product to work, but people actually buy it fully knowing aware of it. Good luck to this generation, I will be waiting for one where the customer who buys the product receive a convenient perfect product.

The management minions in the studios find this copy protection ruse very useful. First, illegal copying is a useful excuse for not making their revenue and profit numbers. They use it to deflect attention away from the lousy job they are doing. Secondly, when they sign up for some sort of copy protection scheme, it gives them a prop to use to show how wonderful they are at managing because they "took action." It's all a big con job. The companies who develop these copy protection schemes realize the truth but they don't care. They just see it as an opportunity to make money.

!!!!!!!!!! MAJOR BREAKTHROUGH !!!!!!!!!!


Sony has just invented a new manufacturing process that they are so confident will prevent pirating, they are allowing everyone to make unlimited copies of all their movies..................



BUT...................



There is one small catch....................





EVERY copy you get will be...........................

Ok on a serious note for actual Bluray users - how is it going to be backward compatible? I know the ps3 is firmware upgradeable via the system updates. How well are other standalone bluray players upgradeable for new protection schemes?

[jagabo]

how is it going to be backward compatible?

As I understand it BD+ is a virtual machine. So the new protection scheme is just a new program that runs on it.

[yoda313]

I'm sorry but what do you mean by virtual machine in this application? I know a virutal machine in the computer operating world is an emualtion of another operating system without needing a physical seperate computer to run it. How does that apply to security systems on the Bluray discs?

[jagabo]

Yes, it's a virtual machine in the same sense. A virtual machine isn't just for other operating systems but an entirely different CPU can be emulated as well.

The decryption program is loaded from the disc and runs on the virtual machine. Since the VM can run any program written for it, it can use any decryption scheme.

Ok. Thanks. That makes it a little clearer.
