Abstract
A DRM technique interoperability system includes an exporter and an importer. The exporter cancels the DRM technique from the contents to which the DRM technique of a DRM device is applied to generate a contents stream, generates a plurality of packets from the contents stream, and transmits the packets to the importer. The importer receives a plurality of packets from the exporter, generates a contents stream from the plurality of packets, applies a DRM technique of a second DRM device to the contents stream, and provides it to the second DRM device.
