Abstract
A rights management system is described in which, subsequent to recording a media resource, client-side equipment receives and stores recording definition information (RDI). The RDI provides information that can be used to recover the keys used to decrypt the media resource. When a client device subsequently wishes to consume the media resource, it can forward the RDI to an operations center. At the operations center, a transcription module validates the client device's rights and converts the RDI into client targeted information (CTI) by recovering the keys used to decrypt the media resource. The client device receives the CTI from the transcription module and uses it to consume the media resource. The CTI has an expiration date, after which it can no longer be used.
