Abstract

Disclosed are a method of constructing information on associate meanings between segments of a multimedia stream, which can describe the cause/effect or abstract/detail relationship between segments of the video streams to efficiently browse the video stream and a method of browsing a video using the same. The present invention defines the cause/effect or abstract/detail relationship between the segments, event intervals, scenes, shots, etc. existing within one video stream or between the video streams, and provides a method of describing the relationship in a data region based on the content of a video stream as well as a method of browsing a video by using the information on the cause/effect or abstract/detail relationship obtained by the aforementioned method. Accordingly, a video browsing on associate meanings is available with easy manipulation and easy access to a desired part, thereby providing an effective video browsing interface for easy browsing of desired segments in a short period of time.

Claims

1. A method of browsing a video using semantic relations information between segments of a multimedia stream characterized by a video browsing interface including a video display view and a key frame or a key region view, the method comprising:

displaying the semantic relations information between segments by the video browsing interface further including key frames or key regions or text for displaying the semantic relations information between the segments; and

performing a video browsing by using key frames or key regions or text displaying the semantic relations information between segments, wherein the semantic relations information between segments is an information on cause/effect or abstract/detail relationships.

2. The method of claim 1, wherein a user can select a case as to whether to shift to a frame corresponding to the selection region or to a segment represented by the selected region, or to a cause segment of the corresponding segment or to an effect segment or to an abstract segment or to a result segment, if the user selects a predetermined display region of the key frame or the key region view.

3. The method of claim 1, wherein each segment is expressed by a node, and the relationship between the segments is expressed by a link in a region displaying the semantic relations information between segments.

4. The method of claim 3, wherein each node is expressed by using the key frame, the key region or a text in the region displaying the semantic relations information between segments.

5. The method of claim 3, wherein the corresponding node and the link are displayed in a graphic structure in the region displaying the semantic relations information between segments.

6. The method of claim 3, wherein the corresponding node and the link are displayed in a tree structure in the region displaying the semantic relations information between segments.

7. The method of claim 3, wherein the corresponding node and the link are displayed in other structures than a graphic structure or a tree structure in the region displaying the semantic relations information between segments, the corresponding segment and the segments related to the semantic relations being dynamically converted and displayed when a predetermined segment is selected.

8. The method of claim 3, wherein a shift is made to a corresponding segment if each node of a graphic view of semantic relations information is selected.

9. The method of claim 1, wherein the region displaying the semantic relations information displays the region displaying the semantic relations information between segments centering around a segment currently being displayed.

10. The method of claim 1, wherein a graphic view displays the semantic relations information and includes a plurality of nodes, and the segment corresponding to a selected node are automatically linked and reproduced.
