First Claim
1. An apparatus for navigating a video, comprising:
- a display to view the video; and
a user interface to navigate the video based on a desired frame from a plurality of representative frames including at least a first representative frame and a second representative, the user interface being provided on the display, whereinthe plurality of representative frames are representative of a predetermined range of a multimedia stream, a semantic relations information is provided 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, and an additional weight value indicates a weight on the second representative frame 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, and wherein said influence is based on the 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.
