Abstract

There are provided a system for automatically generating a multimedia data description scheme (DS), and a system for searching and browsing the multimedia data based on the multimedia data description scheme (DS), the generating system providing the information to describe the multimedia data, and the browsing system allowing to search and browse the desired data by a user based on the multimedia data description scheme (DS), and including DDL parsing means, binary format decoding means, data storage means, browser interface means, and so on.

Claims

1. An automatic generating apparatus of multimedia data description scheme comprising:

user interface means for generating a multimedia data description scheme;

data interface means for data interface between the user interface means and the apparatus;

DDL conversion and generation means for generating a DDL type of description scheme for a predetermined multimedia data selected by the user interface means;

binary format conversion and generation means for generating a binary format (BiM) of description scheme for a predetermined multimedia data selected by the user interface means;

DDL parsing means for parsing the DDL type of description scheme and supplying to the data interface means; and

binary format decoding means for decoding the binary format of description scheme and supplying to the data interface means.

2. The automatic generating apparatus of claim 1, wherein the multimedia data description scheme describes hierarchical summary information of the multimedia data.

3. The automatic generating apparatus of claim 1, wherein the multimedia data description scheme is a description scheme based on the additional description including title/key words for a predetermined scene or portion of the multimedia data.

4. The automatic generating apparatus of claim 1, wherein the user interface means offers the display of the multimedia source, the selection or input of time and key word information of the multimedia source, the supply of segment information, level and location information for the segment and the information to describe the above information to the multimedia data, and the generation of description scheme based on the all information to automatically generate multimedia data description scheme.

5. The automatic generating apparatus of claim 1, wherein the user interface means generates a DDL type or a BiM type of description scheme for the multimedia source, or a BiM type and a DDL type of description scheme for the multimedia source simultaneously to automatically generate the multimedia data description scheme.

6. The automatic generating apparatus of claim 1, wherein the highlight segment and the description scheme for the multimedia data are generated by the user interface means.

7. The automatic generating apparatus of claim 1, wherein the description scheme for the multimedia data is modified or deleted by the user interface means.

8. A multimedia data searching and browsing apparatus comprising:

DDL parsing means for parsing a DDL type of description scheme for multimedia data browsing described as a DDL type of description scheme;

binary format decoding means for decoding a binary format of description scheme for multimedia data browsing described as a binary format of description scheme;

data storage means for browsing multimedia data according to the parsed DDL type of description scheme or the decoded binary format of description scheme; and

browser interface means for outputting the user demands based on the multimedia description scheme stored in the data storage means, and the search result according thereto.

9. The multimedia data searching and browsing apparatus of claim 8, wherein the interface means for searching and browsing comprises means of selecting a multimedia source, means of selecting a browsing method or form for the selected multimedia source, and means of searching and displaying the multimedia according to the selected multimedia source and the browsing method or form.

10. The multimedia data searching and browsing apparatus of claim 9, wherein the interface means displays the key frame to represent a specific portion of the multimedia data based on the description scheme of the selected multimedia data, and replays and displays the portion which the key frame represents.

11. The multimedia data searching and browsing apparatus of claim 9, wherein the selection of a browsing method or form by the interface means, and the searching and browsing according thereto are executed by selecting in a key word or title list, or by searching and displaying the segment of the user input key word.

12. The multimedia data searching and browsing apparatus of claim 9, wherein the searching and displaying of a segment based on the hierarchical summary by the interface means is performed when the multimedia data description scheme offers the hierarchical summary.

13. The multimedia data searching and browsing apparatus of claim 8, further comprising conversion means of converting the description scheme stored in the data storage means for data base, description scheme data base of storing the converted description scheme as data base, and query interface means of browsing the multimedia data suitable for a user query from the data base according to the user query through the browser interface means.

14. The multimedia data searching and browsing apparatus of claim 13, wherein the interface means for searching and browsing comprises means of selecting a multimedia source, means of selecting a browsing method or form of the selected multimedia source, and means of searching and displaying the multimedia according to the selected multimedia source and the browsing method or form.

15. The multimedia data searching and browsing apparatus of claim 13, wherein the interface means displays the key frame to represent the highlight segment of the multimedia data based on the description scheme of the selected multimedia data, and replays and displays the portion which the key frame represents.

16. The multimedia data searching and browsing apparatus of claim 13, wherein the selection of a browsing method or form by the interface means, and the searching and browsing according thereto are executed by selecting in a key word or title list, or by searching and displaying the segment of the user input key word.

17. The multimedia data searching and browsing apparatus of claim 13, wherein the searching and displaying of a segment based on the hierarchical summary by the interface means is performed when the multimedia data description scheme offers the hierarchical summary.
