发明名称 METHOD AND SYSTEM FOR ALLOWING CONTENT PROTECTED BY A FIRST DRM SYSTEM TO BE ACCESSED BY A SECOND DRM SYSTEM
摘要 A method, system, and computer-readable media storing operational instructions for allowing content protected by a first DRM system to be accessed by a second DRM system are disclosed. In one embodiment, a request is received from a host application for a license for content protected by a first DRM system, the first DRM system being different from the host application's DRM system. A license supported by the host application's DRM system is then generated from a license supported by the first DRM system. In another embodiment, a request is received to store content protected by a first DRM system. In response to the request, a portable license for the content is generated from a license supported by the first DRM system. Alternatively or additionally, a portable file format for the content is generated from a file format supported by the first DRM system. The request can come from a first computing platform, and the portable license and/or file format can be generated by a second computing platform. Other embodiments are disclosed, and each of the embodiments can be used alone or together in combination.
