A method of managing access to protected content is disclosed, the method being carried out by a content consumption device including a digital rights management engine (1000; 1220). The method comprises receiving a request to access a piece of protected content, and using the digital rights management engine to evaluate digital rights management objects that make up a licence to determine whether permission to access the protected content should be granted, wherein some of the information needed by the digital rights management engine to access the content needs to be obtained through external digital rights management services. The method further comprises dispatching a service discovery request to locate a node that provides a desired service, and finding candidate service providing nodes, sending a request corresponding to a desired service to a service providing node, receiving a response message from the service providing node, and, if permission to access the protected content is granted, using a media rendering engine to render the content. |
