generating, by a media player, a rights object request message for requesting a rights object corresponding to first content stored in the media player and transmitting the rights object request message; receiving a rights object response message including at least one of the rights object and a uniform resource identifier (URI) of the rights object; and obtaining a rights object using the rights object response message, wherein the first content comprises metadata, which is a content identifier (ID) given by a DRM system or a rights object identifier (ID) provided by a media server, wherein the media server searches the rights object corresponding to the first content by referring to at least one of the content ID and the rights object ID of metadata, and wherein the generating and transmitting of the rights object request message comprises: searching for the media server, which has the rights object corresponding to the rights object request message, using a universal plug and play (UPnP) content directory service (CDS)-based action included in the rights object request message by the media player; and transmitting the rights object request message from the media player to the media server.
