4. 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”

5. 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.

6. 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.

13. 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
