Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a technology that can manage illegal use of contents and a program rating of the contents or the like. SOLUTION: A database describing a list of people permitted for utilizing contents in advance is generated. Furthermore, copyright information is encoded to the contents. In the case that a receiver side receives transmitted contents and decodes the encoded copyright information and detects the copyright information, the copyright information and information to specify a transmission destination are recorded as a log. Then the recorded log is compared with the contents of the database and transmission destinations not described in the database are excluded.
