Windows Vista, HDCP and Digital Rights Management

Microsoft, as you might imagine, intends to support HD DVD and video on all its current operating systems, especially the upcoming Windows Vista. To this end, the company is building support for HDCP into the operating system as part of its suite of DRM (Digital Rights Management) abilities called Output Content Protection Management (OCPM).

Hmm, I wonder how long it will take for someone to "break" the OCPM.

Default Microsoft end-run

For years, the hardware guys and the content guys have sparred over DRM. The content guys whine "Help us" and the hardware guys go "helping you costs money - go away".

But as the hardware gets more computer-based anyway and most of the hardware makers license the op-sys piece from Microsoft, it behooves Microsoft to take up the DRM challenge.

Face it - Microsoft wants to be the gatekeeper for all digital content. If you want to play digital media at home, be it on XBox, cable set-top box, PC, or DVD, then Microsoft wants you to have paid them. If Microsoft offers *successful* DRM, eventually Microsoft can instruct the Universals and the Viacoms to alter their content so that IT WON'T RUN AT ALL unless it detects a Microsoft DRM solution protecting the content.

And Bill will own the world. Viva Gates.

Talking A better way

[Change in topic sorry for the double-postie]

So then the Universals and the Viacoms - because they were stupid - end up being pwned by Bill. They have the choice of distributing content that people can copy or doing as Bill says. And Bill says "Give me more money!"

But there is another way. More secure. Dollar-stable.

The reason the hardware guys won't implement DRM is cost. An additional nickel for a part in a mass-produced DVD is gonna get you fired and yelled at.

But what if we made one of your parts, the D/A chip, cheaper? Well the hardware companies would eat it up. And suppose this D/A chip had DRM you HAD to implement? The hardware companies would say sure!

So Universal and the other big players ...

A] Form a chip consortium
B] Buy a small fab
C] Design a D/A converter that employs DRM AT THE CHIP LEVEL..
D] Design an advanced media [EVD - encrypted video disc] that's paired with the new D/A.
E] Sell it at cost to the hardware makers. Hell sell it at a loss if necessary. But it must be cheaper that current D/A to be adopted.

Then the hardware makers conform out of economic necessity, everyone switches to the EVD format, and the content makers control their destiny because they own hardware production.

Just a thought

Bill Gates already owns the world, which is precisely why Nintendo is dying.

Do then what your saying is, WHat ever OS you run, you still wont be able to open media.

Imposible. BS. Hardware Communicates with software, and vise versa. The software could defeat the hardware.

Default Uhhhh

I suppose - I haven't worked thru all the scenarios and lord knows the guys who hack have alot more experience than I do.

But if the digital information comes off the EVD encrypted and the "new D/A" does the decrypting and conversion inside one chip then where do you ever get the chance to exploit an unencrypted digital stream?

BTW this scheme won't support high-end digital output. But the content mongers don't care about your SPDIF anyway.

Did I just say SPDIF?

And I suppose the truly clever will figure out substitute hardware - a small daughterboard that can replace the ED/A [I oughta spend five minutes with a patent atty.; I need a piece of this]. But how many average Joes are gonna open up a DVD, resolder 50 connections, and risk jail under DCMA?

Hardware encrypt/decrypt is hard to break. How many people you know stealing satetilite TV? The signal is free, grab it with any dish .... but the signal is useless w/o the descrambler box.

Well, you can buy the reciver, but all you need is this flash drive thing (Mine has a SD card it in..I could probably read from it and other stuff If I could get it out..)
