Abstract
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.
