Abstract

A content delivery system, a method thereof, and a content reproducing device are provided. The content reproducing device comprises a content separator, an insufficient content storing section, and a server. The content separator separates or divides content into an insufficient content and a complementary content. The insufficient content storing section stores the insufficient content sent (outputted) from the content separator. The server includes a storing means for storing the complementary content sent from the content separator, and sends the complementary content to the content reproducing device via a network. The content reproducing device acquires the complementary content from the server and the insufficient content from the insufficient content storing section. Thereafter, the content reproducing device reproduces the content using the insufficient content and the complementary content. Thereby, it is possible to provide a system and a method which save the trouble of checkin and/or checkout operation and thus enhance user'"'"'s usability. Further, according to the system and the method, a content provider can charge a user for content each time a user reproduces content.

the content reproducing device acquires the content related information and the first content from the first content storing means, and transmits the content related information to the server; and

the server transmits the second content to the content reproducing device on the basis of the content related information.

7. The content delivery system as claimed in claim 1, wherein:

the first content storing means stores content related information concerned with the second content, and the first content;

the content reproducing device acquires the content related information and the first content from the first content storing means; and

the server authenticates the content reproducing device before transmitting the second content to the content reproducing device, and transmits the second content to the content reproducing device only when the device is authenticated.

9. The content delivery system as claimed in claim 1, wherein:

the first content storing means stores content related information concerned with the second content, and the first content;

the content reproducing device acquires the content related information and the first content from the first content storing means, and transmits the content related information to the server;

the server transmits the second content to the content reproducing device on the basis of the content related information;

the server authenticates the content reproducing device before transmitting the second content to the content reproducing device, and transmits the second content to the content reproducing device only when the device is authenticated.

11. The content delivery system as claimed in claim 1, which used for pay per view.

15. The content delivery method as claimed in claim 13, wherein the server transmits the second content to the content reproducing device on the basis of content related information concerned with the second content.

16. The content delivery method as claimed in claim 14, wherein the server transmits the second content to the content reproducing device on the basis of content related information concerned with the second content.

17. The content delivery method as claimed in claim 13, wherein:

the server transmits the second content to the content reproducing device on the basis of content related information concerned with the second content; and

the server authenticates the content reproducing device before transmitting the second content to the content reproducing device, and transmits the second content to the content reproducing device only when the device is authenticated.
