A digital rights management (DRM) conversion method and apparatus are provided. The DRM conversion method includes: (a) obtaining a first content key for the first content and a second content key for the second content through reciprocal authentication between a DRM conversion apparatus and a DRM conversion server, the DRM conversion apparatus converting the first content into the second content; and (b) converting the first content into the second content wherein the DRM conversion apparatus is disconnected from the DRM conversion server. Accordingly, it is possible to transmit content between devices using different DRM systems even offline with the use of a conversion manager (CM) that performs authentication and DRM conversion operations.
A digital rights management (DRM) conversion method which converts first content that has been created by a first device using a first DRM system into second content for a device using a second DRM system, the DRM conversion method comprising:
A DRM conversion apparatus which converts first content that has been created by a first device using a first DRM system into second content for a device using a second DRM system, the DRM conversion apparatus comprising:
A computer-readable recording medium storing a program for executing a DRM conversion method which converts first content that has been created by a first device using a first DRM system into second content for a device using a second DRM system, the DRM conversion method comprising:
