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 describing information on relations between segments of a multimedia stream, comprising:

describing information on semantic relations between segments including segment locators and description of cause and effect semantic relationships between said located segments based on contents of said located segments.

2. The method of claim 1, wherein the segment locator includes an information on intervals.

3. The method of claim 2, wherein the segment locator includes information on a stream.

4. The method of claim 3, wherein the information on a stream is an information on relative/absolute locations of the stream.

5. The method of claim 3, wherein the information on a stream comprises a unique identifier (ID) for the stream.

6. The method of claim 2, wherein the information on intervals is described as a starting point and an ending point of the segments.

7. The method of claim 2, wherein the information on intervals is described as information on a starting point and a length of the segments.

8. The method of claim 1, further comprising information on an additional weight value with respect to the cause/effect semantic relationship between said located segments so as to order the segments affecting a particular segment or the segments affected by a particular segment.

9. A data structure for describing information on relations between segments of a multimedia stream, comprising:

information that describes semantic relations between segments including segment locators and description of cause and effect semantic relationships between said located segments based on contents of said located segments.

10. A method of describing information on relations between segments of a multimedia stream, comprising:

describing information on semantic relations between segments including segment locators and description of abstract and detail semantic relationships between said located segments based on contents of said located segments.

11. A data structure for describing information on relations between segments of a multimedia stream, comprising:

information that describes semantic relations between segments including segment locators and description of abstract and detail semantic relationships between said located segments based on contents of said located segments.
