Abstract

In a system of a communication network service, a content providing service apparatus has a storage for storing a plurality of pieces of protected contents, a transfer request accepting section for accepting a transfer request from a user for a particular piece of content, and a content transfer section for transferring the particular piece of content to a relay service apparatus. The relay service apparatus has a content holding section operative when the particular piece of content is transferred from the content providing service apparatus for temporarily holding the particular piece of content in a secured area allocated to the user, a delivery request accepting section for accepting a delivery request for the particular piece of content from the user through a terminal apparatus, and a content delivery section for retrieving the particular piece of content requested for delivery from the secured area and for delivering the retrieved particular piece of content to the terminal apparatus of the user through the communication network service. The terminal apparatus reserves the delivered particular piece of content.

3. The system according to claim 1, wherein said transfer request accepting section of said content providing service apparatus accepts said terminal identification information of said terminal apparatus of said user;

said content transfer section of said content providing service apparatus transfers said terminal identification information of said terminal apparatus of said user along with said particular piece of content to said relay service apparatus;

said content holding section of said relay service apparatus operates when said terminal identification information of said terminal apparatus of said user has been transferred along with said particular piece of content for holding said particular piece of content in said storage area allocated in correspondence with said terminal identification information of said terminal apparatus of said user; and

said content delivery section of said relay service apparatus operates upon acceptance of said delivery request for said particular piece of content from said user through said terminal apparatus for retrieving said particular piece of content from said storage area corresponding to said terminal identification information of said terminal apparatus of said user.

4. The system according to claim 1, wherein said content transfer section of said content providing service apparatus has a copyright processing section operative if said copyright protection specification information is attached to said particular piece of content for processing copyright royalty payment when transferring said particular piece of content.

5. The system according to claim 1, wherein said content holding section of said relay service apparatus comprises a deleting section operative if said copyright protection specification information is attached to said particular piece of content which is a music piece reproducible on said terminal apparatus for deleting said particular piece of content from said storage area of said relay service apparatus after said content delivery section transmits said particular piece of content to said terminal apparatus;

and

said content storing section of said terminal apparatus operates if said copyright protection specification information is attached to said particular piece of content for deleting said particular piece of content after reproduction of the music piece by a predetermined number of times.

6. The system according to claim 1, wherein said content providing service apparatus comprises a direct delivery request accepting section operative for accepting a direct delivery request for said particular piece of content from said user through a given communication apparatus only if said copyright protection specification information is not attached to said particular piece of content;

and

a content direct delivery section that retrieves said particular piece of content for which said direct delivery request has been accepted from said storage section and delivers said particular piece of content to said given communication apparatus of said user.

7. A content providing service apparatus for performing a communication network service in combination with a plurality of terminal apparatuses subscribing content of said communication network service and a relay service apparatus for temporarily holding a particular piece of content in a storage area and retrieving said particular piece of content from said storage area to transmit said particular piece of content to one of said plurality of terminal apparatuses, said content providing service apparatus comprising:

a storage section that is provided for storing a plurality of pieces of content, each of which is attached with copyright protection specification information if said piece of content requires copyright protection;

a transfer request accepting section that is provided for accepting a transfer request from a user for said particular piece of content selected from among said plurality of pieces of content stored in said storage section; and

a content transfer section that is provided for transferring said particular piece of content for which said transfer request has been accepted, to said storage area of said relay service apparatus so as to temporarily hold said particular piece of content therein before delivery of said particular piece of content to said terminal apparatus of said user.

8. A relay service apparatus having a storage area and relaying a communication network service in combination with a plurality of terminal apparatuses subscribing content of said communication network service with unique terminal identification information allocated to the respective terminal apparatuses and a content providing service apparatus for accepting a transfer request from a user for a particular piece of content selected from among a plurality pieces of content each of which is attached with copyright protection specification information if said piece of content requires copyright protection, said relay service apparatus comprising:
