Data transferring method and content transferring method

An exporter for transferring data in a Digital Rights Management (DRM) interoperable environment, the exporter comprising:

• an interface configured to:
• receive a capability request message from a control entity that receives a data transmission request message from a client, the data transmission request message requesting a data transmission,
• transmit data describing a capability requested by the capability request message to the control entity, wherein the transmitted data describing the capability is used to determine whether a transformation associated with the requested data transmission is possible and to form a chain for the data transmission,
• establish a secure authenticated channel with a receiving entity identified in receiver information included in an export request received from the control entity, wherein the export request message includes the receiver information identifying the receiving entity, a transfer session identifier identifying a transfer session, and a data identifier identifying a plurality of data,
• transmit, in a single transfer session identified by the transfer session identifier, the plurality of data to the receiving entity using the established secure authenticated channel, wherein the data is any one of content or license, and at least one of the content or license is DRM-interoperable, and
• transmit, to the control entity, an event message that indicates a transmission status of the data and includes the transfer session identifier identifying the transfer session;
• and
• a processor and memory, the processor configured to:
• export the plurality of data identified by the data identifier from a first DRM system.

A system for transferring data in a Digital Rights Management (DRM) interoperable environment, the system comprising:

• one or more computers;
• a computer-readable medium coupled to the one or more computers having instructions stored thereon which, when executed by the one or more computers, causes the one or more computers to perform operations comprising:
• receiving a capability request message from a control entity that receives a data transmission request message from a client, the data transmission request message requesting a data transmission;
• transmitting data describing a capability requested by the capability request message to the control entity, wherein the transmitted data describing the capability is used to determine whether a transformation associated with the requested data transmission is possible and to form a chain for the data transmission;
• establishing a secure authenticated channel with a receiving entity identified in receiver information included in an export request message received from the control entity, wherein the export request message includes the receiver information identifying the receiving entity, a transfer session identifier, and data identifiers identifying a plurality of data,
• exporting the plurality of data identified by the data identifier from a first DRM system;
• transmitting, in a single transfer session identified by the transfer session identifier, the exported plurality of data to the receiving entity using the established secure authenticated channel, wherein the data is any one of content or license, and at least one of the content or license is DRM-interoperable, and
• transmitting, to the control entity, an event message that indicates a transmission status of the data and includes the transfer session identifier identifying the transfer session.
