METHOD OF CONSTRUCTING INFORMATION ON ASSOCIATE MEANINGS BETWEEN SEGMENTS OF MULTIMEDIA STREAM AND METHOD OF BROWSING VIDEO USING THE SAME
First Claim
1. An apparatus for displaying at least one representative frame based on semantic relations information between frames of a multimedia stream, comprisinga display unit having a prescribed display area, a plurality of representative frames including at least a first representative frame and a second representative frame, the representative frame being a frame representative of a predetermined range of a multimedia stream, wherein the first and second representative frames are provided on the prescribed display area of the display unit;
- anda unit configured to;
obtain the representative frame from the plurality of representative frames,obtain semantic relations information between the first representative frame and the second representative frame, the semantic relations information includes information on a relationship between the first representative frame and the second representative frame, andobtain information on an additional weight value indicating a weight on the second representative influenced by the first representative frame,wherein the second representative frame is influenced by the first representative frame based on a cause and effect relationship.

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.
