摘要:
A memory card (110) stores access restriction information (AC1) to a license information hold unit (1440) arranged in a TRM area. Access restriction information (AC1) has information for example of a frequency of reproduction allowed and a number of licenses owned. A controller (1420) in reproducing and transferring content initially confirms access restriction information (AC1) and thereafter effects reproduction and transfer and after the reproduction and transfer are effected updates access restriction information (AC1), as required, for storage in a license information hold unit (1440).
