Portable digital rights for multiple devices
First Claim
1. A Digital Rights Management (DRM) system, comprising:
- a first device configured with;
a removable hardware component configured as a token that is associated with a DRM license of a domain, the DRM license cryptographically bound to the token; and
a removable memory card configured to store protected media content on which the first device is configured to perform actions as permitted by the DRM license;
a second device configured with the removable hardware component and the removable memory card when removed from the first device and installed in the second device, the second device configured to perform the actions on the protected media content as permitted by the DRM license; and
a domain controller configured to;
recognize the second device when the removable hardware component is installed in the second device;
detect that the removable hardware component has been registered on the domain;
initiate domain certification of the second device to enable the second device to perform the actions on the protected media content as permitted by the DRM license, the domain certification further enabling the second device to acquire additional protected media content from a content distributor of the domain via a communication network and to playback the additional protected media content at the second device.

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.

6. A computer-implemented method for Digital Rights Management (DRM), comprising:
-
installing, at a computing device, a removable memory card comprising protected media content, the removable memory card previously installed at an additional computing device; installing a removable hardware component at the computing device, the removable hardware component comprising a token that is associated with a DRM license for a domain, the removable hardware component previously installed at the additional computing device, the installing causing the removable hardware component to be detected by a domain controller of the domain as being previously registered on the domain; initiating a domain certification of the computing device by the domain controller responsive to installing the removable hardware component, the domain certification enabling the computing device to perform actions on the protected media content as permitted by the DRM license, the domain certification further enabling the computing device to acquire additional protected media content from a content distributor of the domain via a communication network and to playback the additional protected media content at the computing device. - View Dependent Claims (7, 8, 9, 10)

11. One or more computer-readable storage devices comprising instructions stored thereon that, responsive to execution at a computing device, cause the computing device to perform operations comprising:
-
initiating a domain certification of the computing device by a domain controller responsive to a removable hardware component being installed at the computing device, the removable hardware component comprising a token that is associated with a DRM license for a domain, the removable hardware component previously installed at an additional computing device, the installing causing the removable hardware component to be detected by the domain controller of the domain as being previously registered on the domain, the domain certification enabling the computing device to perform actions on protected media content as permitted by the DRM license and enabling the computing device to acquire additional protected media content from a content distributor of the domain via a communication network and to playback the additional protected media content at the computing device; and performing the actions on the protected media content as permitted by the DRM license. - View Dependent Claims (12, 13, 14, 15)
