Abstract
A system for protecting contents comprises a first device for storing and reproducing contents purchased by a user; a server for issuing usage rights of contents; and a second device for reproducing contents protection mechanism-applied contents, and if contents to be copied from the first device are not protected by the protection mechanism, obtaining the usage rights from the server and converting the unprotected contents into contents under protection of the protection mechanism. When contents purchased by the user is not protected by the DRM, the DRM-employed reproducing device can obtain usage rights with respect to the corresponding contents from the rights issuer. And then, the purchased contents are converted into the contents that can be protected by the DRM. Accordingly, in the present invention, the contents that is not protected by the DRM can be enjoyed through the DRM-employed reproducing device without causing a problem legally, and thus, user inconvenience of separately and additionally purchasing contents protected by the DRM and a corresponding financial loss can be reduced.

20. A method for protecting digital contents in an apparatus where a digital contents protection mechanism is employed, comprising:
-
when contents are received from a certain device, checking whether the contents are protected by the contents protection mechanism;
if the contents are not protected by the mechanism, rejecting reception of the contents and connecting to a server to obtain usage rights for the contents; and
when usage rights for the contents is obtained, withdrawing the rejection of reception to receive the contents, and converting the received contents into contents which can be protected by the mechanism based on the obtained rights. - View Dependent Claims (21, 22, 23, 24, 25, 26)

27. A method for protecting digital contents of a media reproducing device comprising:
-
attempting transmission of contents by a first device, to which a digital rights management (DRM) is not applied, to a second device to which the DRM is applied;
if the contents are not protected by the DRM, proposing by the second device that the first device convert the contents into DRM contents;
if the first device accepts the proposal, connecting by the second device to a server with reference to URL information contained in the contents and receiving a certain trigger from the server;
when reception of the trigger is checked, transmitting by the second device information required for obtaining contents usage rights to the server;
receiving by the second device information on contents usage rights from the server;
transmitting by the first device the contents to the second device; and
converting by the second device the received contents into DRM contents based on the obtained rights. - View Dependent Claims (28, 29)
