PlayReady Distribution Entities
• Content Packaging – Protect content & Send info to license and distribution servers
• Distribution Servers: Store and distribute content. Microsoft PlayReady technology does not require a specialized Web server for content storage and distribution. For Smooth Streaming it Should be IIS7 with “Media Extensions”

PlayReady Distribution Entities
• License Servers: Store content protection information and rights for using the content. The client must acquire a license before playing protected content (license might be pre-embedded in content file).
• Domain Controllers: determine what the domain represents (a user, a family, or a group of users, for example) and holds a list of entities that are associated with the domain. The Domain Controller also enforces the policy defining how many devices or PCs may join the domain.

PlayReady Distribution Entities
• Metering Servers: With metering, the device maintains a count of how many times a file is played. When the portable device connects to a computer or the Internet, this metering count is uploaded to the content provider. Metering does not alter or affect any behavior on the user’s system and does not identify the user. Metering allows the content provider to accurately assess royalties.

How does it work
• There are 2 key components to FAXS;
A. Packager used in content preparation. Encrypts content with policies such as how long someone can watch offline or have access to content
B. License server grants permissions to consumers. This is where the business logic resides
Note: Requires a “digital certificate set” issued by Adobe to create content that will play back on Flash Player/AIR
