Abstract
Systems, apparatuses, and methods are described for converting digital rights management (DRM) data in a specific protocol to standardized DRM data. The standardized DRM data may be used to secure content delivered to user devices through a content delivery network. If a user device decides to record a content item, a request for authenticating entitlement to the content item may be sent to a network device and the network device may reply with an authentication receipt if appropriate. If the user device later decides to access the content item, the user device may send the authentication receipt back to the network server so that the network server may reply with a decryption key for decrypting the content item.
