Rebuttal to Alexander Grundner's "Incorrect Corrections" on AACS
Rebuttal to Chris Lanier's "Corrections" on AACS | Alexander is questioning some of the information I provided him with after he made some incorrect assumptions on AACS. While I can’t give any other information than what’s below currently, I can say that I have a good track record of knowing a thing or two about AACS. Here’s an article published by TG Daily/Toms Hardware that quotes me based on comments I made on your site, Alex. The same post where you said I was “entitled to my opinion. However, statements like the one below from Josh Peterson, the director of strategic alliances for the Optical Storage Solutions group of HP, lead readers to believe otherwise.” That believing otherwise changed once HP learned the correct information on the technologies in question.
Quote: “AACS is being used in next-gen DVDs and will be supported in Windows Vista, but that DOES NOT mean that AACS defines the usage of the content, only the Content Publisher can (referring to points 2 & 3 in his remarks).”
AACS will be used in both HD DVD and Blu-ray (collectively “next-gen DVDs”), and support will be built into Vista, this is all correct. However AACS will also define the minimum right to always copy, the content owners are free to extend the base terms set by the AACS, however they have no obligation too.
Quote: “Bottom line: "Managed copies" is a feature, not a guaranteed right.”
Sort of. Managed Copies will be a guaranteed right for all HD DVD’s released. You will have the ability to make at least a single Managed Copy. As of this moment, you can consider Managed Copies with Blu-ray a feature, and not a guaranteed right until the BDA releases information on their policy (mainly pertaining too BD+ and ROM Mark)
Quote: “Plus, we don't have control over how much flexibility the Content Publishers want to give PC users. If they want to limit the playback to one PC, they can; or, if they want to do what's theoretically possible, and that's being able to stream the video to other protected devices, they can as well (which I'm all for).”
This will be defined in the AACS. The content owners can add additional copies and much, but there will be a base defined within the AACS. This includes making a single Managed Copy (HD DVD), and being able to move the Managed Copy to “AACS Certified” devices. Note that moving a copy around to devices requires the use of technologies approved by the AACS LA, however not from any content owners (other than those who sit on the AACS LA/Founders)
Quote: “And his last point, is half right. If a Content Publisher allows PC users to make a managed copy and allows Windows Media Player to transcode the copy as a secured Windows media file for use on other compatible devices, then he's right... that is "flow."”
Take out Windows Media Player from the statement and this quote would be perfect. J Anything defined in the AACS isn’t limited to Microsoft technologies.
Quote: “But if users will be limited to one format, which is a different scenario than we have today, where we can take any digital media and convert it to a variety of third party formats, then he's not telling the whole story.”
I have said in all my quotes that the guaranteed right (etc) is set-in-stone for HD DVD. It isn’t for Blu-ray, because the BDA hasn’t released information about where BD+ and ROM Mark play into AACS.
Update: Windows Vista will not include AACS bits anymore. You will need a third party application to enable that playback currently.
