Abstract

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.

Claims

1. A method for transferring resources, performed by a handler in a DRM interoperable system, the method comprising:

receiving an operation request message from a controller, which receives a resource transmission request message from a client, the resource transmission request message including a transport session identifier identifying a transport session and resource chain information identifying multiple resources, and the operation request message including the transport session identifier identifying the transport session and the resource chain information identifying the multiple resources,

wherein the controller is configured to determine whether a transformation of a resource format is to be performed, the determination being made based on destination information included in the resource transmission request message, and

if the transformation is to be performed, the operation request message includes an identification of a resource transformer that supports the transformation;

transmitting, based on the received operation request message, the multiple resources in the transport session identified by the transport session identifier based on a transmission protocol that supports transmitting the multiple resources in a single transport session; and

transmitting an event message to the controller, the event message including information indicating transfer status of the multiple resources and the transport session identifier,

wherein the information indicating transfer status of the multiple resources includes a resource index identifying each of the resources which is transmitted in the transport session and transfer status information indicating transfer status of the resource corresponding to the resource index.

2. The method of claim 1,

wherein the transmission protocol supports variable frame sizes, each of the resources is divided into multiple frames, each of the frames has a header that indicates a size of a payload of the respective frame, and the resource index identifying each of resources is inserted before the header of the first frame of each of the resources.

3. The method of claim 1, wherein transfer status information indicating transfer status of the resource corresponding to the resource index includes at least one of:

a start element indicating the transmission of a the resource corresponding to the resource index has started, a completion element indicating the transmission of a the resource corresponding to the resource index has been successfully completed, a progress-done element indicating progress of the transmission of a the resource corresponding to the resource index, or an error element indicating the transmission of a the resource corresponding to the resource index has resulted in an error.

4. The method of claim 3,

wherein the transmission protocol supports variable frame sizes, each of the resources is divided into multiple frames, each of the frames has a header that indicates a size of a payload of the respective frame, and the resource index identifying each of resources is inserted before the header of the first frame of each of the resources.

5. A system for transferring resource, in a DRM interoperable system, 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 an operation request message from a controller, which receives a resource transmission request message from a client, the resource transmission request message including a transport session identifier identifying a transport session and resource chain information identifying multiple resources, and the operation request message including the transport session identifier identifying the transport session and the resource chain information identifying the multiple resources

wherein the controller is configured to determine whether a transformation of a resource format is to be performed, the determination being made based on destination information included in the resource transmission request message, and

if the transformation is to be performed, the operation request message includes an identification of a resource transformer that supports the transformation;

transmitting, based on the received operation request message, multiple resources in the transport session identified by the transport session identifier based on a transmission protocol that supports transmitting the multiple resources in a single transport session; and

transmitting an event message to the controller, the event message including information indicating transfer status of the multiple resources and the transport session identifier,

wherein the information indicating transfer status of the multiple resources includes a resource index identifying each of the resources which is transmitted in the transport session and transfer status information indicating transfer status of the resource corresponding to the resource index.

6. The system of claim 5,

wherein the transmission protocol supports variable frame sizes, each of the resources is divided into multiple frames, each of the frames has a header that indicates a size of a payload of the respective frame, and the resource index identifying each of resources is inserted before the header of the first frame of each of the resources.

7. The system of claim 5, wherein transfer status information indicating transfer status of the resource corresponding to the resource index includes at least one of:

a start element indicating the transmission of a the resource corresponding to the resource index has started, a completion element indicating the transmission of a the resource corresponding to the resource index has been successfully completed, a progress-done element indicating progress of the transmission of a the resource corresponding to the resource index, or an error element indicating the transmission of a the resource corresponding to the resource index has resulted in an error.

8. The system of claim 7,

wherein the transmission protocol supports variable frame sizes, each of the resources is divided into multiple frames, each of the frames has a header that indicates a size of a payload of the respective frame, and the resource index identifying each of resources is inserted before the header of the first frame of each of the resources.
