8,245,312, "Method and apparatus for digital rights management," assigned to Samsung (KR).
A method of managing the digital rights of a remote device is disclosed. The method includes receiving a warrant including information that the use of content is allowed, issued from a main device having the replay right for the content, transmitting the warrant to a service-providing device, and receiving the content provided by the service-providing device.
8,239,962, "Processing rights in DRM systems," assigned to Philips (NL).
This invention relates to a method of processing rights relating to content, that can be communicated between devices. Typically, a Digital Rights Management (DRM) system imposes limitations of use and distribution, imposed by the service provider, content provider or distributor. The method of the invention renders it possible for a user who has received DRM rights to restrict the right further. The invention is more particularly related to the receipt of DRM rights to Authorized Domain Digital Rights Management (AD-DRM) systems and the introduction of user attributed rights in the form of further restrictions introduced to the received DRM rights. The invention further relates to a Rights Program Template (RPT) facilitating the introduction of such further restrictions in a user friendly way. Finally, the invention relates to a system supporting the method of the invention.
