  • Patent number: 8205001
    Abstract: The present disclosure provides a system for accessing content secured according to differing digital rights management protocols. The system comprises a device that presents the content and a client component loaded on the device that uses and requests content according to a first digital rights management protocol. The system includes a first content server that receives a request for and provides content according to the first digital rights management protocol and a second content server that receives a request for and provides content according to a second digital rights management protocol. A mediation component maps requests and responses between the client component and the second content server, mediating between the first and second digital rights management protocols. The disclosure contemplates mediating between open digital rights language (ODRL) and extensible right markup language (XRML) digital rights management protocols as well as other digital rights management protocols.
