| Abstract: |
A contents management system provides a user who already downloaded valid contents with a mechanism capable of downloading the same contents in a duplication manner. A system for delivering contents checks whether contents which are about to be purchased by the user are the same as contents which are in a validity term and which are already downloaded by the user. If so, the system prepares a new contents ID, DL information and meta information for duplicated buying, and makes duplicated buying of the same contents possible. |
