DVD-Audio's CPPM Circumvented

Posted by timothy on from the everything-that-rises-must-converge dept.

Bodysurf writes "After DVD-Video's CSS encryption was broken in 1999, the music industry chose a much more secure copy-protection method for DVD-Audio called Copy Protection for PreRecorded Media (CPPM). This protection scheme has remained publicly uncracked, but it was circumvented recently, providing the ability to save the unencrypted digital audio data. CDFreaks has the details."

    Probably nobody uses DVD-Audio. The effort spent cracking the copy protection will be proportional to the popularity of the medium. When the DVD Audio section at your local record store is as large as the CD section, we may see some more time being spent on such things.
