PlayReady is a media file copy prevention technology from Microsoft that includes encryption, output prevention and digital rights management (DRM).
[1][2] The main differences relative to previous DRM schemes from Microsoft are: PlayReady competes with other proprietary DRM schemes and even more with DRM-free software, most notably Apple's FairPlay introduced in iTunes and QuickTime.
Microsoft released the first version of the PlayReady suite (Porting Kit for devices, PC SDK and runtime, Server SDK) in June 2008.
Silverlight 2.0, released in October 2008, supports content restricted with PlayReady.
