License management system and method for playing contents on home network

摘要

A system and a method for allowing a plurality of devices interconnected for home networking to use the contents only by a single license without acquiring separate licenses for the devices. A transceiver module transmits/receives data to/from various devices. A license search module receives a request to issue a license from a home device through the transceiver module, searches for a corresponding formal license in a license storing module, and transmits the search result to both a license request module and a temporary license issuing module. The license request module requests the license server to issue the corresponding formal license when the formal license does not exist in the license storing module, and stores the license downloaded from the license server. The temporary license issuing module issues a temporary license to the corresponding home device through the transceiver module, based on the formal license stored in the license storing module.
