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 computer-implemented method for browsing a video using semantic relations information between segments of a multimedia stream characterized by a video browsing interface, the computer-implemented method comprising:

obtaining semantic relations information between segments including at least a first segment and a second segment, wherein the semantics relations information includes information on a relationship between the first segment and the second segment, and wherein the second segment is influenced by the first segment based on a cause and effect relationship;

obtaining information on an additional weight value indicating a weight on the second segment among a plurality of non-consecutive segments influenced by the first segment, wherein the additional weight value is associated with the cause and effect relationship between the first segment and second segment; and

performing a video browsing by using the semantic relations information and the information on the additional weight value.

2. The method of claim 1, wherein the method further comprising:

obtaining segment locators, the segment locators identifying locations of the first segment and the second segment.

3. The method of claim 2, wherein the segment locators include information on intervals and information on a stream.

4. The method of claim 3, wherein the information on a stream is an information on relative or 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 3, wherein the information on intervals is described as a starting point and an ending point of the segments.

7. The method of claim 3, wherein the information on intervals is described as information on a starting point and a length of the segments.

8. A non-transitory computer-readable medium used for describing semantic relations between segments of a multimedia stream, the computer-readable medium comprising:

semantic relations information that describes semantic relations between segments including at least a first segment and a second segment, wherein the semantic relations information includes information on a relationship between the first segment and the second segment, and wherein the second segment is influenced by the first segment based on a cause and effect relationship; and

information on an additional weight value indicating a weight on the second segment among a plurality of non-consecutive segments influenced by the first segment, wherein the additional weight value is associated with the cause and effect relationship between the first segment and second segment, and wherein the semantic relations information and the information on the additional weight value are used for browsing a video.

9. A computer-implemented method for browsing a video using semantic relations information between segments of a multimedia stream characterized by a video browsing interface, the computer-implemented method comprising:

obtaining semantic relations information between segments including at least a first segment and a second segment, wherein the semantic relations information includes information on a relationship between the first segment and the second segment, and wherein the second is influenced by the first segment based on an abstract and detail relationship;

obtaining information on an additional weight value indicating a weight on the second segment among a plurality of non-consecutive segments related to the first segment, wherein the additional weight value is associated with the abstract and detail relationship between the first segment and second segment; and

performing a video browsing by using the semantic relations information and the information on the additional weight value.

10. A non-transitory computer-readable medium used for describing semantic relations between segments of a multimedia stream, the computer-readable medium comprising:

semantic relations information that describes semantic relations between segments including at least a first segment and second segment, wherein the semantic relations information includes information on a relationship between the first segment and the second segment, and wherein the second segment is influenced by the first segment based on an abstract and detail relationship; and

information on an additional weight value indicating a weight on the second segment among a plurality of non-consecutive segments related to the first segment, wherein the additional weight value is associated with the abstract and detail relationship between the first segment and second segment, and wherein the semantic relations information and the information on the additional weight value are used for browsing a video.
