Interfaces for Secure Content Providers

A secure content provider (SCP) is a plug-in component that enables Windows Media Device Manager to transfer and request rights information from DRM-protected content. Microsoft provides an SCP component that can handle DRM-protected WMA and WMV files. If your device or application will use DRM-protected content of other formats, it should create an SCP component by implementing all of these interfaces. Otherwise, you will not need to use these interfaces.
