Abstract

A sending unit obtains data designated by a user from a plurality of data stored in a database. Then, the sending unit sends the obtained data through a communication line to a delivery center at which the user is to receive the data. When doing so, the sending unit sees to it that sending of the data designated by the user will be completed by a date designated by the user. An accumulator is installed at the delivery center, and accumulates data sent by the sending unit. A providing unit, which is also installed at the delivery center, obtains the data designated by the user from the accumulator, records the data in a recording medium, and provides it to the user.

Claims

1. A data providing system comprising:

a storage which stores a plurality of data;

a sending unit which obtains data designated by a user from said storage and sends the obtained data to a delivery center at which the user receives the obtained data; and

a providing unit which is installed at said delivery center and provides the data sent from said sending unit to the user,

wherein said sending unit completes sending all or a part of the data designated by the user, by a date designated by the user.

2. The data providing system according to claim 1, further comprising a scheduler which plans in accordance with a predetermined condition a schedule for completing sending all or a part of the data designated by the user by the date designated by the user,

wherein said sending unit sends all or a part of the data designated by the user to said delivery center in accordance with the schedule planned by said scheduler.

3. The data providing system according to claim 2, wherein:

said providing unit comprises a recorder which records data in a recording medium and thus provides the data to a user; and

said sending unit completes sending a part of the data designated by the user by the date designated by the user, and sends the rest of the data while said recorder records the part of the data in a recording medium.

4. The data providing system according to claim 2, further comprising an accumulator which is installed at said delivery center and accumulates data sent from said sending unit,

wherein said providing unit obtains all or a part of the data designated by the user from said accumulator and then provides it to the user.

5. The data providing system according to claim 4, further comprising a determiner which determines whether or not all or a part of the data designated by the user is accumulated in said accumulator,

wherein said scheduler plans the schedule in a case where said determiner determines that all or a part of the data designated by the user is not accumulated in said accumulator.

6. The data providing system according to claim 2, wherein the predetermined condition includes at least one of the date designated by the user, a data amount of the data designated by the user, a traffic amount of a communication line between said sending unit and said delivery center, and a capacity of said communication line.

7. The data providing system according to claim 4, wherein said accumulator deletes data accumulated therein in accordance with a predetermined rule.

8. The data providing system according to claim 7, wherein said accumulator sets a term in which data accumulated therein remains valid, and in a case where the user does not receive the data before the set validity term expires, deletes the data.

9. The data providing system according to claim 1, wherein:

said providing unit comprises a recorder which records data in a recording medium and thus provides the data to a user; and

said sending unit sends all of the data designated by the user so that said recorder can complete recording all of the data designated by the user by the date designated by the user.

10. The data providing system according to claim 9, further comprising a scheduler which plans in accordance with a predetermined condition a schedule for said recorder to complete recording all of the data designated by the user by the date designated by the user,

wherein said sending unit sends all of the data designated by the user in accordance with the schedule planned by said scheduler.

11. The data providing system according to claim 10, further comprising an accumulator which is installed at said delivery center, and accumulates data sent from said sending unit,

wherein said providing unit obtains all of the data designated by the user from said accumulator and then provides it to the user.

12. The data providing system according to claim 11, further comprising a determiner which determines whether or not all of the data designated by the user is accumulated in said accumulator,

wherein said scheduler plans the schedule in a case where said determiner determines that all of the data designated by the user is not accumulated in said accumulator.

13. The data providing system according to claim 10, wherein the predetermined condition includes at least one of the date designated by the user, a data amount of the data designated by the user, a traffic amount of a communication line between said sending unit and said delivery center, a capacity of said communication line, and a recording speed of said recorder.

14. The data providing system according to claim 11, wherein said accumulator deletes data accumulated therein in accordance with a predetermined rule.

15. The data providing system according to claim 14, wherein said accumulator sets a term in which data accumulated therein remains valid, and in a case wherein the user does not receive the data before the set validity term expires, deletes the data.

16. A data providing method comprising:

an obtaining step of obtaining data designated by a user from a plurality of data stored in a database;

a sending step of sending the data obtained in said obtaining step to a delivery center at which the user receives the data through a communication line; and

a providing step of providing at said delivery center the data sent in said sending step to the user,

wherein said sending step includes a step of completing sending all or a part of the data designated by the user by a date designated by the user.
