4. The server computer system for selling digital contents according to claim 2, wherein the server computer system comprises link information storing means for storing, in the rack of the customer who purchased the digital contents, link information including a contents ID identifying the digital contents when the digital contents received from the sales center server are identical with digital contents already stored in the rack.

5. The server computer system for selling digital contents according to claim 4, wherein, when the list sending means receives the request for a list with the user ID and one of the player terminal Ids from the player terminal, the list sending means creates the contents list for the user ID and the player terminal ID and sends it to the player terminal, and when the contents sending means receives the download request for digital contents with information including the user ID and the player terminal ID from the player terminal via the network, the contents sending means downloads contents information including the digital contents, the expiration date, and the maximum number of replays for the user ID and the player terminal ID to the player terminal from the rack.

6. A player terminal for replaying digital contents using a network, wherein the player terminal is connected via the network to user terminals, a server computer, and a sales center server storing the digital contents therein, and

the player terminal comprises:

displaying means for displaying a list of the digital contents stored in the server computer on a screen;

means for requesting download of digital contents selected by a customer from the list displayed by the displaying means; and

storing and replaying means for storing contents information including the downloaded digital contents and replaying the digital contents.

7. The player terminal according to claim 6, wherein the contents information includes the digital contents and information on the expiration date and the maximum number of replays for the player, and the player terminal comprises erasing means for erasing the digital contents stored by the storing and replaying means when the expiration date indicated by the information on the expiration date has been passed or when the digital contents has been replayed maximum times indicated by the information on the maximum number of replays.

8. A system for selling digital contents using a network, wherein user terminals, player terminals for replaying digital contents, a sales center server storing the digital contents therein, and a server computer system are interconnected via the network, and

the system for selling digital contents are constituted by:

the server computer system comprising creating means for creating a rack in a database as a depository for digital contents for each customer in response to a creation request from the user terminal, storing means for storing digital contents received from the sales center server in the rack, list sending means for receiving a request for a list of the digital contents from the player terminal via the network and creating the list from the customer'"'"'s rack to send it to the player terminal, and contents sending means for sending digital contents selected via the network by the customer using the player terminal to the player terminal in response to a download request for the selected digital contents;

the player terminal comprising displaying means for displaying a list of digital contents stored in the server computer on a screen, means for requesting download of the digital contents selected by a customer from the list displayed by the displaying means, and storing and replaying means for storing contents information including the downloaded digital contents and replaying the digital contents;

the sales center server comprising delivering means for accepting the customer'"'"'s purchase request from the user terminal and delivering the digital contents purchased by the customer to the server computer via the network; and

the user terminal comprising requesting means for requesting, via the network, creation of the rack for each customer from the server.

9. The system for selling digital contents using a network according to claim 8, wherein the server computer system comprises:

the creating means for creating a rack for a user ID in the database and registers customer information with the rack as user information on the rack when the creating means receives via the network the rack creation request including the customer information constituted by the user ID, a password, and one or more player terminal IDs that have been input by the user terminal, and for changing the player terminal IDs when the creating means accepts via the network a request for change of the player terminal IDs registered with the rack;

link information storing means for storing, in the rack of the customer who purchased the digital contents, link information including a contents ID identifying the digital contents when the digital contents received from the sales center server are identical with digital contents already stored in the rack;
