"The horse has really bolted with respect to DVDs. They're out there, people cannibalise them all the time with DVD decrypters and people can get movies off them like there's no tomorrow.
"The industry needed something much better to deal with the piracy problem. Studios said in a high-def world, we're going to have to have a very different way of viewing content.
"In Longhorn, the computer determines that a video card is not faked or being intercepted, so there's a lot of onus on the writers of the drivers. It also checks If there are digital or analogue drivers. If only digital outputs are in use, it will then check a display has HDCP capability high bandwidth digital content protection. The communication between the video card and the device is encrypted and only decrypted by the display device itself. If all that is true, the operating system says, "ok, gotcha, we are running on a protected video path which is OK for premium content HD-DVDs, BluRay, or a video file that someone has marked."
"If you don't comply with PVP, we're going to downscale the quality upon playback you're going to get a lower quality version; you're not going to get the high def content the way it was intended to be viewed. You'll find that most plasma displays have HDCP already. But this isn't available in computer monitors. I have not been able to find a single monitor that supports it. We are going to see a lot of change in this space.
"We have more information at Output Content Protection and Windows Longhorn
"The hardware vendors all know about it but aren't yet making monitors with it built in, so now it's up to you [the users] to say, "where's my HDCP?"
"There's a LOT of encryption and decryption going on. We communicate on the PCI Express bus in a fully encrypted format because it is considered a public bus.
"The downside is that all your existing flat panel monitors and projectors aren't going to work with high-def videos in Vista. Bad news."
How about "Buy me a new Display or Fuck your HDCP"....
