The U on iTunes - Terms
FairPlay (Apple Store DRM)
FairPlay is a digital rights
management (DRM) technology created by Apple Inc., based on technology
created by the company Veridisc. FairPlay is built into the QuickTime
multimedia software and used by the iPod, iTunes, and iTunes
Store. Every file purchased from the iTunes Store with iTunes
(except songs to be distributed by the EMI Group starting in
May 2007) is encoded with FairPlay. FairPlay digitally encrypts
files and prevents users from playing these files on unauthorized
computers.
Note, iTunes U doesn't support any FairPlay or any other DRM.
In putting recordings on iTunes U a digital format is used and
an analog format can be converted using an analog-to-digital converter.
