Abstract:
In a protected media path for delivering content from a source to a sink, a source authority (SOTA) on behalf of the source decides with regard to a policy corresponding to the content that a particular type of action with the content is to be refused, and provides a particular enabler to an application. The provided enabler includes information and methods necessary for the application to obtain data necessary to respond to the refusal. The application receives the enabler at an interface thereof and the interface applies a common interaction procedure to run the enabler to obtain the data necessary to respond to the refusal.
