Method for transmitting contents for contents management technology interworking, and recording medium for storing program thereof

摘要

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.

1. A method for transmitting data between a first contents management device and a second contents management device, the method comprising:
initiating a negotiation between the first and the second contents management devices to determine a transmission format associated with the second contents management device; canceling a first digital rights management (DRM) applied to data received from the first contents management device, the data including a content packet, right information packet and a metadata packet; converting the data received from the first contents management device into data having the transmission format associated with the second contents management device; transmitting the data having the transmission format associated with the second contents management device to the second contents management device, the transmission format including a resolution, codec, and compression rate for the content packet, a description language of the right information packet, and a description language of the metadata packet; and applying a second digital rights management (DRM) to the data to provide the data to the second contents management device.
