What are the implications of BluRay three-way DRM choice for high-def DVD

[Biggles]

What are the implications of BluRay three way DRC?

I wonder if this means an end to authoring own dvds, or ripping dvds...

This seems like an appropriate place to put up a link to this:

http://www.aacsla.com/specifications/specifications.htm

... the publicly-released specifications for the AACS to be used in both the next-generation formats. It makes use of AES, about which you can read more here:

It means that the average person won't be able to backup their movies, but pirates will still have no trouble copying the discs. It was the same with DVDs until deCSS came out. These copyprotections NEVER affect pirates, just legitimate users.

I'm sure there will be some DVD authoring tools to remove it. I tend to follow the rule "if it can be encrypted, it can be decrypted it's all a matter of figuring out how"

@ChronoCross,

It's worth reading the first few paragraphs of the 'security' section under my second link...

I remember some NSA papers where they say that 1024bit encryption is no more save enough coz with a budged of 1.000.000 $ you could crack it in "just" 1 year! So they wanna use 2048bit encryption soon... XD

Also look at the fact that the decrypters(aka hardware devices) will have the ability to read these disks so there has to be a pretty standard way of doing it. Or perhaps I'm misunderstanding the actual use behind the security features, it being that it's not used in playback but only in copy protection?

Not certain whether this applies: Microsoft Protection (Longhorn) (http://download.microsoft.com/download/5/D/6/5D6EAF2B-7DDF-476B-93DC-7CF0072878E6/output_protect.doc)

I haven't read the entire doc, but what I understand from it is that HD-DVD requires a "capable" display, ie, one able to communicate with the "output" that it is providing protection. No available video card does this at this time. I'm not sure that any HD-Display does so at this time.

Displays with HDCP will do it.

Even if it's encrypted all the way to the TV, someone will just put their camera in front of the TV and film it like they do movies at the theaters. They aren't going to stop it - all they are doing is pissing off legal customers. "I'm sorry, you have to buy a $3000 TV to watch these programs." All that does is ENCOURAGE people to make and acquire "illegal" copies.

If you think about it, as long as it's an LCD TV, the resulting recording from a camera should be pretty good. I've seen excellent pictures of LCDs where the displayed image is very clear. CRTs are much worse in that respect given the scanned nature of the display.
