摘要:
An apparatus and method for transferring a Rights Object (RO) for a content between devices via a server, wherein a sending device converts a first RO taken by itself to encode into a second RO, and sends an RO move request message including the second RO to the server, whereas the server converts the second RO included in the RO move request message into a third RO and transfers the third RO to a receiving device, whereby the receiving device receives the third RO from the server for installation, wherein the sending device deletes or modifies the first RO at an appropriate time point.

摘要:
A method and system for managing at least one DRM agent intending to join or leave a user domain in a Digital Rights Management (DRM) is provided, in which a Domain Enforcement Agent (DEA) manages the joining and leaving of the DRM agent resident in a home network it manages, and a Domain Authority (DA) provides a domain key to a DRM agent joining the user domain.
摘要:
A method for managing a specific domain (or user domain), for example leaving the domain by a specific device after fully returning a Rights Object (RO) taken by the specific device, instead of deactivating the RO, when leaving the specific domain, the method in which the device desiring to leave the specific domain moves its RO to another device desiring to join the specific domain and thereafter leaves the specific domain under the control of a Domain Authority/Domain Enforcement Agent (DA/DEA).

摘要:
A method for protecting unprotected content in digital rights management (DRM) and a device thereof. When non-protected content stored in a non-DRM device is to be transferred to a DRM device, the non-protected content are converted into protected content and then are transferred to other user's device.
摘要:
A secure transmission of a device management message via a broadcast (BCAST) channel, by which a BCAST server can securely transmit a device management message including an authentication value to a plurality of terminals via a one way BCAST channel, and accordingly the terminals is not required to use a separate channel for authenticating the device management message received from the BCAST server.
摘要:
A method of digital rights management for a broadcast-multicast service, the method comprising receiving a request from a terminal to join a service domain having a common group key; transmitting encryption of one or more service encryption keys using the common group key to the terminal that requested to join; and allowing the terminal to share the same contents and the same services with one or more other devices within the service domain.

摘要:
A Digital Rights Management (DRM), and particularly a method for sharing a Rights Object (RO) of a certain DRM content between devices, wherein a certain device requests a Rights Issuer (RI) to upgrade its existing RO, and moves or copies the upgraded RO by the request to at least one or more other devices via a wired/wireless medium, thereby sharing the RO with the other devices.
