[edit] Patent term circumvention?

Is ROM-Mark intended as a way to extend the BDA's exclusive rights to BD-ROM past the expiry date of the essential Blu-ray Disc patents, in order to avoid the loss of royalties that happened once the CD-ROM patents expired? --Damian Yerrick (talk | stalk) 02:24, 24 April 2007 (UTC)

The issue of the use of drm to implement controls that ride roughshod over the final user's legal rights is really a separate issue. In any event, ROM-Mark is not really designed with that sort of purpose in mind. 82.29.215.250 (talk) 11:47, 5 April 2008 (UTC)

[edit] The Actual Purpose of ROM-Mark

I think the article might be misleading. ROM-Mark, as I understand it, is a mechanism whereby data is hidden on the disk which describes attributes of the machine on which the disk was pressed. A player can check the data and compare it with an assessment of the disk itself to see if what is there is a genuine authorised disk. That sort of protection is aimed at fakers who press bit-copies of genuine disks. It might also have applications in preventing games machines from playing games which are on recordable media rather than genuine pressed disks. It also has applications in proving that fake disks are fake, or in tracing their source if they are unauthorised production from authorised sources.

My understanding is that it does not address the issue of those who crack and decrypt the content and then burn it in an unprotected form to recordable media. That sort of of copy is usually treated by players in the same way as a home made movie. 82.29.215.250 (talk) 11:54, 5 April 2008 (UTC)
