Each playback device comes with a binary tree of secret device and processing keys.The processing key in this tree, a requirement to play the AACS encrypted discs, is selected based on the device key and the information on the disc to be played.In a response to the events occurring on Digg and the call to "Spread this number", the key was rapidly posted to thousands of pages, blogs and wikis across the Internet. My legally purchased copy of Power DVD is refusing to play Bluray discs made after a certain date: Astonishingly, this is "standard practice" for all versions of Power DVD.Internet users began circulating versions of this image, calling it the Free Speech Flag, in blog posts on dozens of websites and as user avatars on forums such as Digg.The first fifteen bytes of the 09 F9 key are contained in the RGB encoding of the five colors, with each color providing three bytes of the key.The compromised players can still be used to view old discs, but not newer releases without encryption keys for the compromised players.
