The device which receives manner and the aforementioned license which transfer the digital contents license

摘要

A method of transferring a content license (L2) to a first device (10) from a second device (20). The second device (20) renders (202) the license (L2) unusable to itself and sends (208) this license ([L2]) to the first device (10) that verifies (214) that it may import the license ([L2]) which is the case if it has rendered one of its own licenses ([L1],) unusable to it, but has not exported this license ([L1],). If so, it updates (216) its license information (F1) so that it may import one license less and makes (218) the received license usable. The first device (10) also receives a content file (S2) that corresponds to the received license. The invention enables flexible transfer of licenses, as e.g. the second device (20) may export the license to the first device (10) without receiving anything in return, but the exportation does provide it with the right to import a further license. Also provided is a device.
