A device for playing digital media comprises a connection for receiving content over a network and a digital rights management (“DRM”) module that identifies rights for the received content by accessing a DRM data structure. The DRM data structure can be a temporal cache. The device receives content and the DRM module identifies identifiers associated with the content and/or the device. The DRM module uses the identifiers to access the DRM data structure and identify rights associated with the content. The identified rights are applied to the content to prevent and/or permit activities with respect to the content. Permitted activities for the content may be presented in a display of the device and can be updated as the content changes and/or as rights associated with content change. Content providers and other authorized entities can change the rights associated with particular content by updating the DRM data structure. |
