Informationsaufzeichnungsvorrichtung und Informationswiedergabevorrichtung mit Lizenzverwaltung

摘要

The information reproduction device for reproducing the contents information based on the license information added to the contents information and required for reproducing the contents information, includes a determining section (1) for determining whether the encrypted contents information is the officially copied contents information or privately copied contents information based on the contents of the license information, and a reproduction section (4,5,6) configured to reproduce the contents information determined as the privately copied contents information by the determining section under more severe restrictions than the officially copied contents information. Thus, the contents copied by the proper route (officially copied contents) can be distributed in a more advantageous form than the contents copied without proper authorization.
