Contents distribution system for handling secondary products utilizing raw material contents

摘要

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.
