A contents distribution system uses a copyright rental use scheme in which the
economical burden on the users at a time of utilizing contents can be reduced to
a reasonable level, and appropriate fees can be collected for the copyrights of
the contents created and provided at each stage by the raw material creators and
the secondary product creators. In this system, the secondary product creator can
create the secondary product contents by incorporating the raw material contents
for free, and sell the secondary product contents. The end-user pays respective
utilization fees to the secondary product creator and each raw material provider
at a time of the purchasing the secondary product contents.
