Abstract:
1. A DRM (digital right management) interoperable system comprising: content handlers; a client configured to: transmit a request message, wherein the request message requests to transmit multiple contents from a source to a destination and includes a session identifier identifying a session for transmitting the multiple contents; a domain manager configured to: authenticate the client, associate the client with a domain, and manage the domain; and a controller configured to: receive the request message from the client, form a chain that includes the content handlers, and control the content handlers to transmit the content from the source to the destination through the chain, wherein each pair of the content handlers included in the chain supports a transmission protocol supporting transmission of multiple contents in a single session, and transmits the multiple contents, based on the transmission protocol, wherein each of the contents is divided into multiple frames, each of the frames has a header that indicates how long the payload of the each of the frames is, and a content index identifying each of the contents is inserted before the header of the first frame of each of the contents, based on the transmission protocol in the session that is identified by the session identifier, and wherein each of the content handlers transmits an event message to the controller, the event message describing the actual status of the transmission of each content at the moment of the transmitting of the event message, and the event message includes at least one of a start element indicating a content transmission has started, a completion element indicating the content transmission has been successfully completed, a progress-done element indicating progress of the content transmission, and an error element indicating the content transmission has resulted in an error.
