Primetime Cloud DRM supports nearly all of the features currently available with Primetime DRM. However, due to some of the DRM features requiring communication with a customer’s back-end business rules subsystem, some features are not available with Primetime Cloud DRM.
The features currently not supported by Primetime Cloud DRM are:
Content packaged with an External CEK (where the license server requests the content’s CEK from an external key management system)
Device Domains
Advanced License Chaining
License Return/Revocation
PHLS/PHDS. These are protection schemes that do not make use of a License Server
