Many of you have been asking me in emails lately: “What is the difference between Silverlight DRM and Smoooth DRM?” The answer is quite simple.

Silverlight DRM is a DRM schema based on PlayReady DRM that supports encryption of Windows Media Content for decryption and playback via the Silverlight Player. Content can be delivered from any HTTP or Windows Media Services source. This technology is available today from BuyDRM.

Smooth DRM is a DRM schema based on PlayReady DRM that supports encryption of Smooth Streaming Content for decryption and playback via the Silverlight Player. Content must be delivered using Microsoft’s IIS7 webserver which offers Smooth Streaming support. This technology will be available in the next 30 days from BuyDRM.
