发明名称 Rights request method
摘要 Method for management of digital rights, wherein digital media content is provided from a content provider (1) in a protected format to a user client (2), such as a mobile phone. The client initiates execution of an operation associated with said digital media content, but finds out that the client lacks the appropriate digital rights for performing said operation. The client automatically transmits a rights request signal (5), requesting digital rights for said operation, to a rights issuer device (3). The rights issuer device creates a new rights object related to said operation, and transmits it to said client. The client downloads the rights object and then reinitiates the operation. <IMAGE>
