An information processing apparatus is provided including a memory
configured to store content data and corresponding content management
information. The content management information defines a rule set
relative to reproduction of the content data. The content data and
management data are embodied in a first format. A processor is configured
to convert the first format of the content management information into a
second format, different from the first format. A transmitter is provided
to transmit the second format of the content management information to
another information processing apparatus.
