I wonder if they mean encryption till you're blue in the face kind of innovation?
CD's were for a long time only able to be made by large companies in the beginning. When the very people who invented it all decided to release
"burners" onto the market, we had the same old arguments as with the recordable audio cassette and then later, the video recorder. All the while
screaming "Devil!", they still managed to increase profits year after year. Anyway, back to digital...
They tried (I believe) certain proprietary methods to protect the CD content but even that didn't work for long. With the advent of DVD, they built
the encryption into the disc. A bored student (from Finland if memory serves) set about working out how it all worked and after a while discovered
that the key was some huge prime number or something like that. Maths is not my strong point and my brain tends to automatically fuzz over the
incomprehensible stuff (to me).
With Bluray they upped it even more. All the components involved in displaying the contents of the disc need to be "compliant" (hardware chips?)
thereby proving you are only playing it on authorised and legal equipment of their choosing and, again if memory serves, they somehow maintain a right
to revoke your viewing privileges by retro-actively removing a piece of data on one of their servers.
I don't have bluray so don't have hands on experience with discs on a PC but I did read that someone, somewhere, somehow, managed to find "the key" by
luck with a debugger (no, it's not rude!) under Windows and they "went from there" so to speak. Whatever they can make, some clever nerd can
break...eventually. At least, that's how it's gone so far and I have seen plenty of bluray rips on the net. They are way too big for me to download
though and besides, my old PC couldn't play them without stuttering anyway.
