The Microsoft Windows Media Digital Rights Management (DRM) is an end-to-end DRM system that offers content providers and retailers a flexible platform for the secure distribution of digital media files. The following video demonstrations show the process of protecting and delivering valuable content using the Windows Media Rights Manager Software Development Kit (SDK).
The content packaging, distribution, and licensing process begins with a piece of encoded content. The content packager packages the content as an encrypted Windows Media file and then shares the secrets for decrypting and licensing the file with the license issuer. The encrypted content is distributed to consumers through the Internet, CD, or other conventional means. Consumers are then issued a license to play the file, and use it according to the business rules defined for it.
You can learn about this process by watching these four demonstration videos.
