ABSTRACT:
An arrangement for managing a media file having an associated DRM license is provided by enabling the copying of the media file stored on a source medium to a target medium only when both the source medium and the target medium are held in custody by a media server. The media server writes a copy of a media file and a copy of the associated DRM license from the source medium to the target medium. Upon confirmation that the copy of the DRM license was successfully written to the target medium, the DRM license and media file on the source medium are overwritten. The result is that the target medium contains both the media files and the DRM licenses which are locked to the target medium.
