Abstract

The present invention relates to a data management system which collectively manages material data by synchronizing the material data stored in a material server with an OA server.

The system is characterized by comprising functions of: sequentially storing material data including generated video/audio signals in at least a material server; determining that the material data stored in the material server has either a synchronous attribute or an asynchronous attribute with respect to at least an OA server which stores material data to be transmitted to a broadcast network; and, synchronizing, between the material and OA servers, processing operations with respect to the same material data existing in both the material and OA servers and respectively having a synchronous attribute.

Claims

1. A data management system comprising:

at least a first server which sequentially stores material data including generated video/audio signals;

at least a second server which stores material data to be transmitted; and

an electronic device having attribute determination means for determining that the material data stored in the first server has either a synchronous attribute or an asynchronous attribute with respect to the second server, and synchronization means for synchronizing processing operations with respect to the same material data that exist in both the first and second servers, and that have a synchronous attribute respectively.

2. The data management system according to claim 1, wherein

the attribute determination means determines that each of folders for containing files each of which organizes the material data has a synchronous attribute or an asynchronous attribute, and

the synchronization means synchronizes the material data to be contained in the folder having a synchronous attribute with the second server.

3. The data management system according to claim 1, wherein

the electronic device further includes operation designation means for designating a processing operation to be executed with respect to the material data stored in the first server, and

when the processing operation is designated with respect to the material data having a synchronous attribute, the synchronization means executes the processing operation with respect to the material data that has been synchronized with the second server.

4. A data management method comprising:

sequentially storing material data including generated video/audio signals in at least a first server;

determining that the material data stored in the first server has either a synchronous attribute or an asynchronous attribute with respect to at least a second server which stores material data to be transmitted; and

synchronizing, between the first and second servers, processing operations with respect to the same material data existing in both the first and second servers and respectively having a synchronous attribute.

5. A computer-readable recording medium on which is recorded a program for:

sequentially storing material data including generated video/audio signals in at least a first server;

determining that the material data stored in the first server has either a synchronous attribute or an asynchronous attribute with respect to at least a second server which stores material data to be transmitted; and

synchronizing, between the first and second servers, processing operations with respect to the same material data existing in both the first and second servers and respectively having a synchronous attribute.
