holding content identification information which has been added to identify the content to be processed by said transaction, in association with said state information.

12. The processing state management method according to claim 10 , further comprising:

generating a request signal to request said distribution server to carry out a transaction to register said content in a content database of said distribution server; and

storing said state information as representing registration in progress after said request signal has been sent to said distribution server until notification of completion of said transaction is received from said distribution server.

13. The processing state management method according to claim 10 , further comprising:

generating a request signal to request said distribution server to carry out a transaction to delete said content from a content database of said distribution server, and

storing said state information as representing deletion in progress after said request signal has been sent to said distribution server until a notification of completion of said transaction is received from said distribution server.

14. The processing state management method according to claim 11 , further comprising:

holding a predetermined flag in association with said content identification information after said request signal has been sent to said distribution server until the notification of completion of said transaction is received from said distribution server.

15. The processing state management method according to claim 11 , further comprising:

retrieving the held state information based on a state information confirmation signal to request a confirmation of said state information when the state information confirmation signal is received from a user device which is owned by a user;

generating a state response signal to send the retrieved state information to said user device; and
