the server includes a delivering unit delivering content data to the client apparatus through a network; and

the client apparatus includes;

a receiving unit receiving the content data; and

an accumulation permitting unit permitting accumulation of the content data received from the server in a case where information indicating permission for accumulation is present.

2. A system according to claim 1, wherein:

the content data delivered from the server is encrypted; and

the client apparatus includes;

a referring unit referring to decoding information; and

a decoding unit decoding the content data received from the server in accordance with the decoding information.

3. A system according to claim 2, comprising a saving unit saving the decoded content data in a case where accumulation of the content data is permitted.

4. A system according to claim 3, wherein the saving unit of the client apparatus saves the decoded content data in a protected device in which copying of saved data is not permitted.

5. A system according to claim 2, wherein the client apparatus includes an outputting unit outputting the decoded content data in a form viewable by a user.

6. A system according to claim 2, wherein the server includes an encrypting unit encrypting the content data to be provided.

7. A system according to claim 1, wherein the information indicating permission for accumulation is provided by a purchase procedure for content data corresponding to the information.

8. A system according to claim 1, wherein

the server includes:

a first issuing unit issuing the decoding information; and

a second issuing unit issuing the information indicating permission for accumulation.

9. A system according to claim 2, wherein

the server includes a first server having a delivering unit delivering the content data and a second server having a issuing unit issuing the decoding information.

10. An electronic apparatus, characterized by comprising:

an inputting unit inputting content data; and

an accumulation permitting unit permitting accumulation of the content data in a case where information indicting permission for accumulation is present.

11. An electronic apparatus according to claim 10, wherein the inputting unit inputs the content data to be delivered from a server through a network.

12. An electronic apparatus according to claim 10, wherein

the content data is encrypted, and

the electronic apparatus further comprises:

a referring unit referring to decoding information; and

a decoding unit decoding the content data received from the server in accordance with the decoding information.

13. An electronic apparatus according to claim 12, comprising a saving unit saving the decoded content data in a case where accumulation of the content data is permitted.

14. An electronic apparatus according to claim 13, wherein the saving unit saves the decoded content data in a protected device in which copying of saved data is not permitted.

15. An electronic apparatus according to claim 12, comprising an outputting unit outputting the decoded content data in a form viewable by a user.

16. An electronic apparatus according to claim 10, wherein the information indicating permission for accumulation is provided by a purchase procedure for content data corresponding to the information.

17. A method of sending and receiving content data in a system including a server and a client apparatus, comprising the steps of:

delivering content data to the client apparatus through a network by the server;

receiving the content data in the client apparatus; and

permitting accumulation of content data received in the client apparatus in a case where information indicating permission for accumulation is present.

18. A method of processing content data in an electronic apparatus, comprising the steps of:

inputting the content data; and

permitting accumulation of the content data in a case where information indicting permission for accumulation is present.

19. A program for causing a computer, which delivers content data to a client apparatus, to execute the steps of:

delivering the content data through a network; and

issuing information indicating permission for accumulation that permits the client apparatus to save the content data to be delivered.

20. A program according to claim 19, comprising the steps of:
