摘要：
An audio object (AOB) for which corresponding rights management information (RMI) has been generated by a license management apparatus, and an AOB for which RMI does not exist are written into a recording medium for use in an SDMI system which includes the license management apparatus. Each AOB is put in correspondence with a migration permission flag (MPF). When the corresponding AOB is the AOB for which RMI does not exist, the relevant MPF is set to on so as to show that a migration procedure is permitted. When the corresponding AOB is the AOB for which RMI has been generated by the license management apparatus, the relevant MPF is set to off so as to show that a migration procedure is not permitted.
