CONSTITUTION: A domain manager generates domain information. The domain manager encodes the generated domain information with a public key. The decoded information is registered in a domain management server. The devices proceeding to the domain are registered in the domain manager. The devices receive the decoded domain information. When the device requests the contents by connecting a contents server, the contents server transmits the contents.
