Abstract

A data management system and method is disclosed, which is applicable to an AV data processing system capable of acquiring and storing AV data. The data management method includes grouping AV data acquired by the AV data processing system into a plurality of related index data and statistic data, comparing the related index data and statistic data, and executing corresponding addition/deletion operations based on comparing results, thereby maintaining an integrity of the AV data acquired by and stored in the AV data processing system.

Claims

1. A data management system applicable to an audio/video (AV) data processing system capable of acquiring and storing AV data, the data management system comprising:

a data grouping module for grouping the AV data acquired by the AV data processing system into a plurality of related index data and statistic data;

a comparison module for comparing the related index data and statistic data derived from the data grouping module; and

a processing module for executing corresponding addition/deletion operations based on comparing results derived from the comparison module, thereby maintaining an integrity of the AV data acquired and stored by the AV data processing system.

2. The data management system of claim 1, wherein the AV data processing system is a digital AV monitoring system.

3. The data management system of claim 1, wherein the index data includes an initial recording time, an ending recording time, a camcorder serial number, a camcorder name, a recording item name, and a size of recording item.

4. The data management system of claim 3, wherein the size of recording item is used for determining whether the AV data have a correct size or not.

5. The data management system of claim 3, wherein the statistic data includes a key character corresponding to the recording item name, a statistic camcorder serial number corresponding to the camcorder serial number, a length of recording time corresponding to the initial recording time and ending recording time, a yes/no of completing recording, and a statistic initial recording time corresponding to the initial recording time.

6. The data management system of claim 5, wherein the yes/no of completing recording is used to decide whether the AV data is successfully acquired or not.

7. The data management system of claim 1, wherein the processing module deletes the index data if the statistic data related to the index data do not exist or are incomplete, or creates new related index data based on the statistic data if the index data related to the statistic data do not exist or are incomplete.

8. The data management system of claim 7, wherein the processing module further deletes the statistic data based on the comparing results derived from the comparison module if the statistic data related to the index data do not exist or are incomplete.

9. A data management method applicable to an AV data processing system capable of acquiring and storing an AV data, the data management method comprising the following steps:

(1) grouping the AV data acquired by the AV data processing system into a plurality of related index data and statistic data;

(2) comparing the grouped related index data and statistic data; and

(3) executing the corresponding addition/deletion operations based on comparing results derived from step (2), thereby maintaining an integrity of the AV data acquired and stored by the AV data processing system.

10. The data management method of claim 9, wherein the AV data processing system is a digital AV monitoring system.

11. The data management method of claim 9, wherein the index data includes an initial recording time, an ending recording time, a camcorder serial number, a camcorder name, a recording item name, and a size of recording item.

12. The data management method of claim 11, wherein the size of recording item is used for determining whether the AV data have a correct size or not.

13. The data management method of claim 11, wherein the statistic data includes a key character corresponding to the recording item name, a statistic camcorder serial number corresponding to the camcorder serial number, a length of recording time corresponding to the initial recording time and ending recording time, a yet/no of completing recording, and a statistic initial recording time corresponding to the initial recording time.

14. The data management method of claim 13, wherein the yes/no of completing recording is used for determining whether the AV data are acquired successfully or not.

15. The data management method of claim 9 further comprising deleting the index data based on the comparing results if the statistic data related to the index data do not exist or are incomplete, or creating new related index data based on the statistic data if the index data related to the statistic data do not exist or are incomplete.

16. The data management method of claim 15 further comprising deleting the statistic data if the statistic data related to the index data do not exist or are incomplete.
