A method of registering a legacy device, a method of transferring data, and a method of authenticating a legacy device are provided. The method of registering a legacy device by using a virtual client, which allows the legacy device to access a domain, includes: receiving unique information on the legacy device from the legacy device which requests the domain to register the legacy device; searching a registrable legacy device list including the unique information on the legacy device which can be registered in the domain for the unique information on the legacy device; and requesting a domain manager, which manages the domain, to register the legacy device, when the unique information on the legacy device is included in the registrable legacy device list, and not allowing the legacy device to be registered in the domain when the unique information on the legacy device is not included in the registrable legacy device list.

Legacy device registering method, data transferring method and legacy device authenticating method

Transmitting a resource and providing information in a resource in a Digital Rights Management (DRM) interoperable system includes: transmitting the resource in a transport session by using at least two handlers; and receiving from the handlers an event message including identification information of the transport session and information which indicates a transfer status of the resource. In addition, the information which indicates the transfer status of the resource may include: a resource index capable of identifying the resource; and information on a transfer status of a resource corresponding to the resource index. Accordingly, information related to transmission of resources can be easily provided in an event form.

Method for transferring resource and method for providing information

A method of managing a domain, a method of extending a domain, and a method of selecting a reference point controller are provided. The method of operating the domain includes: receiving a request for authenticating a reference point controller from a reference point controller candidate; invalidating a membership of the stored reference point controller; generating a unique reference point controller membership for verifying that the reference point controller candidate is a new reference point controller; and transmitting the generated reference point controller membership to the reference point controller candidate. Accordingly, even when an error occurs in the reference point controller, the function of the reference point controller can be rapidly replaced by using the reference point controller candidate.

Domain managing method, domain extending method and reference point controller electing method

The present invention relates to a method of managing a domain employing a multi-domain manager and a domain system. The method of managing a domain employing a multi-domain manager includes designating a primary domain manager, configuring the domain by registering a domain device with the primary domain manager, designating at least one secondary domain manager of the domain devices, and managing the domain through conjunction of the primary domain manager and the secondary domain manager. Thus, domain management can be performed efficiently by employing a multi-domain manager.

Method for managing domain using multi domain manager and domain system

A method of controlling data transfer, a method of controlling content transfer, a method of obtaining content processing information, and a system for transferring content are provided. The method of controlling data transfer in a data interoperable environment includes: receiving a request for transmitting data from a client; gathering information on entities which are to participate in transmitting data; forming a chain including at least two entities by using the gathered information on the entities; transmitting a plurality of data through the chain; and receiving an event message for representing a transmission status of the data transmitted from at least one of the entities included in the chain. Accordingly, it is possible to control a transmission of the data so that the plurality of data can be transmitted through a single session and to receive the transmission status of the data as an event message.

Data transfer controlling method, content transfer controlling method, content processing information acquisition method and content transfer system

A method of transferring data in which a secure authenticated channel is established with a receiving entity corresponding to receiver information included in a received control message, when receiving the control message from a control entity, a format of received plurality of data is transformed according to content format transformation information included in the control message, when receiving the plurality of data from a predetermined transmission entity in a chain constructed by a control of the control entity, the transformed plurality of data is transmitted to the receiving entity through the established secure authenticated channel, and an event message for representing a transmission status of the data is transmitted to the control entity. Accordingly, it is possible to transmit the plurality of data through a single transmission session and provide a transmission status of each data through an event.

Data transferring method

In a method of transferring data in a data interoperable environment, a secure authenticated channel is established with a receiving entity corresponding to receiver information included in a received control message, when the control message is received form a control entity, a plurality of data designated by the control entity are transmitted to the receiving entity through the established secure authenticated channel, and an event message for representing a transmission status of the transmitted data is transmitted to the control entity. Accordingly, it is possible to transmit the plurality of data through a single transmission session and provide a transmission status of each data through an event.

Data transferring method and content transferring method

In a method of transferring data in a data interoperable environment, a secure authenticated channel is established with a receiving entity corresponding to receiver information included in a received control message, when the control message is received from a control entity, a plurality of data designated by the control entity are transmitted to the receiving entity through the established secure authenticated channel, and an event message for representing a transmission status of the transmitted data is transmitted to the control entity. Accordingly, it is possible to transmit the plurality of data through a single transmission session and provide a transmission status of each data through an event.

A method and system for processing content are provided. The method of processing content includes: receiving source data from a first system; interoperable-processing the source data and generating a target data; and transmitting the target data to a second system, the first system or the second system include at least one of access control system, copy protection system and use control system. Accordingly, it is possible to easily process non-compliant content in the DRM interoperable system.

Method and system for processing content

A DRM interoperable system is provided. The DRM interoperable system includes: a domain manager which manages a domain; first and second devices which are authenticated by the domain manager and registered in the domain; and a control unit which gathers information on entities that are to participate in transmission of data when the first device requests the second device to transmit the data, controls at least two entities so that a chain including the at least two entities is constructed by using the gathered information on the entities, and controls the at least two entities so that a plurality of data is transmitted to the second device through the chain. Accordingly, it is possible to provide a DRM interoperable environment in which data can be effectively transmitted.
