Abstract

The present invention relates to a content management system and method of content management on a portable device. The content management system of the present invention includes a storage unit which stores at least one content file, a content list manager which creates a content list of contents files satisfying at least one monitoring condition and manages the content list on the basis of events occurring in the storage unit, and a monitoring unit which monitors the events occurring in the storage unit and transmits information on the events to the content list manager.

Claims

1. A content management system having a processor, comprising:

a digital living network alliance (DLNA) interface for transmitting and receiving multimedia content;

a storage unit which stores at least one content file comprising multimedia content received through the DLNA interface; and

a monitoring unit which monitors the at least one content file stored in the storage unit based on a monitoring condition, generates an event signal corresponding to a particular event if an event occurs with regard to any of the content file stored in the storage unit and transmits the event signal to a content list manager,

wherein the content list manager creates a content list of content files satisfying at least one monitoring condition in the content file stored in the storage unit and updates the content list on the basis of the event when the event signal is received from the monitoring unit, and

wherein the monitoring unit permits reconfiguration by a user of a default setting of said at least one monitoring condition in the content file of a device having the content list, and wherein an addition event copies the content file satisfying the monitoring condition and further stores the content file with a different file name.

2. The content management system of claim 1, wherein the content list manager transmits a monitoring command having the monitoring condition to the monitoring unit, and the monitoring unit starts monitoring the events in response to the monitoring command.

3. The content management system of claim 2, wherein the monitoring unit includes:

an agent, which interfaces between the content list manager and the monitoring unit, to receive the monitoring command from the content list manager and transmit the information on the events to the content list manager; and

a monitoring command executer which monitors the events in accordance with the monitoring command received from the agent and transmits a monitoring result to the agent.

4. The content management system of claim 2, wherein the monitoring condition includes at least one of a file extension for distinguishing types of contents and a file path.

5. The content management system of claim 4, wherein the monitoring unit determines whether the event is the addition event or a deletion event of a content file of which file extension belongs to the monitoring condition, when the monitoring condition is the file extension.

6. The content management system of claim 4, wherein the monitoring unit determines whether the event is an addition or deletion event of a content file of which file path belongs to the monitoring condition, when the monitoring condition is the file path.

7. The content management system of claim 6, wherein the addition event stores the content file satisfying the monitoring condition into the storage unit.

8. The content management system of claim 6, wherein the deletion event moves the content file satisfying the file path to another file path.

9. The content management system of claim 1, wherein the event includes a content identifier, a file path, and an event identifier of the content file to which the event occurs.

10. The content management system of claim 9, wherein the contents list manager requests detailed information on the content file to the monitoring unit on the basis of the event and updates the content list on the basis of the detailed information received from the monitoring unit.

11. A content management method comprising the steps of:

storing at least one content file comprising multimedia content received through a digital living network alliance (DLNA) interface into a storage unit;

registering at least one monitoring condition for monitoring by a monitoring unit of the at least one content file;

creating a content list of content files satisfying the monitoring condition in the at least one content file stored in the storage unit;

monitoring the at least one content file stored in the storage unit based on the monitoring condition;

receiving generating an event signal if an event occurs corresponding to status change with regard to any of the at least one content file stored in the storage unit, wherein the event signal corresponds to a particular event and is transmitted upon a change being recognized; and

updating the content list on the basis of the event;

wherein the monitoring unit permits reconfiguration by a user of a default setting of said at least one monitoring condition in the content file of a device having the content list, and wherein an addition event copies the content file satisfying the monitoring condition and further stores the content file with a different file name.

12. The content management method of claim 11, wherein the monitoring condition includes at least one of a file extension and a file path of the content file.

13. The content management method of claim 11, wherein the event includes a content identifier, a file path, and an event identifier of the content file to which the event occurs.

14. The content management method of claim 11, wherein the step of receiving the event further comprises the steps of:

transferring a monitoring command including the monitoring condition; and

receiving the event in response to the monitoring occurrence information.

15. The content management method of claim 14, wherein the step of receiving event further comprises the step of:

determining whether the event is the addition event or a deletion event of a content file of which file extension belongs to the monitoring condition, when the monitoring condition is the file extension.

16. The content management method of claim 14, wherein the step of receiving the event comprises the step of:

determining whether the event is an addition or deletion event of a content file of which file path belongs to the monitoring condition, when the monitoring condition is the file path.

17. The content management method of claim 16, wherein the addition event stores the content file satisfying the monitoring condition into the storage unit.

18. The content management method of claim 16, wherein the deletion event moves the content file satisfying the file path to another file path.

19. The content management method of claim 11, wherein the step of updating the content list further comprises the steps of:

updating the content list according to detailed information on the content file on the basis of the event.
