Abstract

System, method, and multi-level object data structure thereof for browsing a multi-media data, the method for browsing a multimedia data using a multilevel object data structure including the steps of (1) receiving multimedia information and multiple supplementary information on each object in the multimedia information on the same time, (2) separating the multimedia information and the multiple supplementary information, (3) displaying the multimedia information, and (4) browsing/searching supplementary information related to a particular object from the multiple supplementary information, and displaying the supplementary information when a user requests for browsing/searching the supplementary information related to the particular object.

Claims

1. A method implemented by an apparatus for using multimedia data, the apparatus including a processor, a storage device and a display, the method comprising:

storing, in the storage device, metadata describing at least a portion of a video program, the described portion of the video program including at least one segment depicting a first character played by a first actor, said metadata having a multi-level hierarchical structure and including character list data describing persons associated with said video program, wherein said character list data allows content referencing based on user input, and wherein the character list data includes a first character list item corresponding to the first character depicted in the video program, the first character list item including a character name to identify the first character and an actor name to identify the first actor playing the first character in the video program; and

using the processor in searching for said at least one segment depicting said first character based on said metadata to playback said at least one segment on the display.

2. The method of claim 1, further comprising:

receiving said at least one segment of the video program; and

playing back said received segment on the display.

3. The method of claim 2, wherein receiving said at least one segment of the video program includes receiving the entire video program from a digital broadcasting system.

4. The method of claim 1, wherein searching for said at least one segment depicting said first character based on said metadata includes using information in the first character list item.

5. The method of claim 1, wherein storing the metadata includes receiving the metadata from a digital broadcasting system.

6. The method of claim 1, wherein the first character list item is a container in the hierarchical structure and includes a character element and an actor element, the character element including the character name and the actor element including the actor name.

7. The method of claim 6, wherein the actor element further includes additional information about the first actor.

8. An apparatus for using multimedia data, the apparatus comprising:

a display;

a storage device; and

a processor configured to;

store, in the storage device, metadata describing at least a portion of a video program, the described portion of the video program including at least one segment depicting a first character played by a first actor, said metadata having a multi-level hierarchical structure and including character list data describing persons associated with said video program, wherein said character list data allows content referencing based on user input, and wherein the character list data includes a first character list item corresponding to the first character depicted in the video program, the first character list item including a character name to identify the first character and an actor name to identify the first actor playing the first character in the video program; and

search for said at least one segment depicting said first character based on said metadata to playback said at least one segment on the display.

9. The system of claim 8, wherein the processor is further configured to:

receive said at least one segment of the video program; and

play back said received segment on the display.

10. The system of claim 9, wherein receiving said at least one segment of the video program includes receiving the entire video program from a digital broadcasting system.

11. The system of claim 8, wherein searching for said at least one segment depicting said first character based on said metadata includes using information in the first character list item.

12. The system of claim 8, wherein storing the metadata includes receiving the metadata from a digital broadcasting system.

13. The system of claim 8, wherein the first character list item is a container in the hierarchical structure and includes a character element and an actor element, the character element including the character name and the actor element including the actor name.

14. The system of claim 13, wherein the actor element further includes additional information about the first actor.
