Abstract
A system, device and method for allowing protected content to be transferred to end user communication devices that support different digital rights management (DRM) formats or schemes than the DRM format of the content provider. The method includes providing a Limited Rights Issuer (LRI) that issues content and associated digital rights to one or more of the end user devices within a domain defined by a Domain Authority with which the LRI has registered. The Limited Rights Issuer also translates content and associated digital rights information from the DRM format of an upstream DRM system to the DRM format of a downstream DRM system, which includes the end user devices within the defined domain. The system allows select end user devices to enjoy interoperability of content protected under different DRM schemes, while allowing content providers to still maintain a suitable level of DRM protection for their content.
