Well said. Thanks. As antiRepublicrat said, it is about control. Any time you hear RIAA/MPAA or their enablers like Sony, Intel, Microsoft or Apple talk about "trust" or "security", when speaking of media, you can be assured one thing; it is not you who is trusted, nor is the security for your benefit..

Sony lost a court case that went all the way to the Supreme Court many years ago concerning your right to have the ability to tape things. I believe the case in question was the recording of Television content to videotape, though the ruling has since been applied to casettes and other similar media. Now, they want to implement the restrictions they could not win in court by technology that you will not be allowed to circumvent even if you previously had the rights to do so. For instance, if you buy a CD, they don't want you to be able to cut a disk for use in your car. They also don't want you to be able to use it in your mp3 player, or anything else. They've already purchased enough congresscritters to make copyright perpetual and now they want the ability to dictate how you can use items you purchase into perpetuity. Nice huh?

It all sounds insane.

The communication schema is the following: the OS COPP Driver (Certified Output Protection Protocol) verifies with the graphic card bios to check if it is legitimate or not. Once this verification is done, the card then goes to the monitor KSV, a unique 40 bit key, which will authorize (or not) the reading and displaying of the movie after comparison with a data base provided by the HDCP consortium.

For example, here are all the steps of HDCP certification when a Silicon Image chip is involved:

Ain't it all ironic, for those of us old enough to remember the Betamax versus Disney/Universal case?
