Abstract

Disclosed is a method for content update from a server to a client terminal in a dynamic content delivery (DCD) system, comprising receiving a first message containing an identification information of one or more contents available for update from the server by the client terminal, sending a second message containing the identification information of an specific content to be updated among the one or more contents to request content update to the server; and receiving a third message containing the content or the address thereof corresponding to the identification information contained in the second message to respond to the second message.

Claims

1. A method for content update between a server and a client terminal in a dynamic content delivery (DCD) system, the method comprising:

sending a first message to the client terminal, wherein the first message contains an identification information of one or more contents available for update;

sending a second message to request content update in response to the first message, wherein the second message contains the identification information of an specific content to be updated among the one or more contents; and

sending a third message in response to the second message, wherein the third message contains the content or the address thereof corresponding to the identification information contained in the second message.

2. The method in claim 1, wherein the first message contains session-ID to identify a session between the server and the client terminal.

3. The method in claim 1, wherein the identification information contained in the first message includes channel-ID and/or content-ID.

4. The method in claim 3, wherein the identification information contained in the second message includes channel-ID and/or content-ID.

5. The method in claim 1, further comprises:

sending a fourth message from the client terminal to the server to provide the result of content update for the content included in or referenced by the third message; and

receiving the fourth message by the server.

6. The method in claim 5, either the first message or the third message contains the information to request the fourth message.

19. The method in claim 1, wherein the client terminal receives the first and third messages and sends said second message.

7. A method for content update from a server to a client terminal in a dynamic content delivery (DCD) system, the method comprising:

sending a request message to request content update from the client terminal to the server when a notification message to initiate the content update is received by the client terminal or on demand content update request, wherein the notification message contains an identification information of one or more contents available for update and the request message contains the identification information of an specific content to be updated among the one or more contents;

receiving the request message by the server and sending a response message to respond to the request message, wherein the response message contains the content or the address thereof corresponding to the identification information contained in the second message; and

receiving the response message by the client terminal.

8. The method in claim 7, wherein the notification message contains session-ID to identify a session between the server and the client terminal.

9. The method in claim 7, wherein the identification information contained in the notification message includes channel-ID and/or content-ID.

10. The method in claim 9, wherein the identification information contained in the request message includes channel-ID and/or content-ID.

11. The method in claim 10, further comprises:

sending a conformation message from the client terminal to the server to provide the result of content update for the content included in or referenced by the third message; and

receiving the conformation message by the server.

12. The method in claim 11, either the request message or the response message contains the information to request the conformation message.

13. A dynamic content delivery (DCD) system for content update from a server to a client terminal, the system comprising:

a transmitter for sending a first message to the client terminal, wherein the first message contains an identification information of one or more contents available for update;

a receiver for receiving a second message from client terminal to request content update to the server,

wherein the second message contains the identification information of a specific content to be updated among the one or more contents, with the transmitter sending a third message in response to the second message,

wherein the third message contains the content or the address thereof corresponding to the identification information contained in the second message, and

wherein the client terminal receives the first message from the server, sends the second message to the server, and receives the third message from the server.

14. The system in claim 13, wherein the first message contains session-ID to identify a session between the server and the client terminal.

15. The system in claim 13, wherein the identification information contained in the first message includes channel-ID and/or content-ID.

16. The system in claim 15, wherein the identification information contained in the first message includes channel-ID and/or content-ID.

17. The system in claim 13, wherein

sending a fourth message is sent from the client terminal to the server to provide the result of content update for the content included in or referenced by the third message with the fourth message received by the server.

18. The system in claim 17, wherein either the first message or the third message contains the information to request the fourth message.

20-24. -24. (canceled)

25. A method for content update from a server by a client terminal in a dynamic content delivery (DCD) system, the method comprising:

receiving a first message to the client terminal, wherein the first message contains an identification information of one or more contents available for update;

sending a second message to request content update, wherein the second message contains the identification information of an specific content to be updated among the one or more contents; and

receiving a third message to respond to the second message, wherein the third message contains the content or the address thereof corresponding to the identification information contained in the second message.

26. The method in claim 25, wherein the first message contains session-ID to identify a session between the server and the client terminal.

27. The method in claim 25, wherein the identification information contained in the first message includes channel-ID and/or content-ID.

28. The method in claim 27, wherein the identification information contained in the second message includes channel-ID and/or content-ID.

29. The method in claim 25, further comprises:

sending a fourth message from the client terminal to the server to provide the result of content update for the content included in or referenced by the third message; and

receiving the fourth message by the server.

30. The method in claim 29, either the first message or the third message contains the information to request the fourth message.

31. A method for content update from a server by a client terminal in a dynamic content delivery (DCD) system, the method comprising:

sending a request message to request content update to the server when a notification message to initiate the content update is received or on demand content update request, wherein the notification message contains an identification information of one or more contents available for update and the request message contains the identification information of an specific content to be updated among the one or more contents; and

receiving a response message to respond to the request message from the server, wherein the response message contains the content or the address thereof corresponding to the identification information contained in the second message.
