CSS isn't patented. It's a very simple 56-bit encryption that can be brute forced in realtime on an embedded system using 3 lines of perl code conveniently available off of numerous T-Shirts (thus making the code protected speech under the 1st Ammendment in the US and therefore not subject to the DMCA).
The protection on CSS was entirely by way of only letting license holders see the code. It was so weak that it was first cracked by a 15 year old kid (and brute-forced shortly afterwards). I'm surprised the big Studios haven't sued the DVD consortium into the ground over how weak the 'unbreakable' DVD encryption turned out to be. -Adam drew wrote: > As i understand it the part of the player that is protected is the CSS > (Content Scrambling System), this is patented technology of which the > region coding system is part.
