Abstract

Portable digital rights for multiple devices is described. In an embodiment, a digital rights management (DRM) system includes a first device with a removable component configured as a token that is associated with a DRM license. The first device also includes a removable memory card that stores protected media content on which the first device can perform actions as permitted by the DRM license. The DRM system also includes a second device that can have the removable component and the removable memory card when removed from the first device and installed in the second device such that the second device can perform the actions on the protected media content as permitted by the DRM license.
