摘要： Provided is a system for removing digital rights management (DRM) resources from digital content playback devices. Materials protected by DRM are stored on the playback devices and a separate device is provided for access to the materials. The system may be inserted into multiple devices and provides the resources necessary for accessing the DRM protected material on each device when inserted. The DRMP is coupled either wirelessly or through available connections to the playback device to provide DRM resources. Multiple playback devices are able to operate independently while maintaining the portability of the protected materials.
