Abstract

The present invention relates to a video summary describing plan which describes video summary through metadata. The video summary provides a summary viewing function, a navigating function and a browsing function, and has feasibility for effectively searching the required video content. According to the invention, a hierachical summary describing plan (DS) comprises a highlight grade DS at least, and selectively comprises a summary topic list DS. The highlight grade DS describes the highlight grade and can comprise zero or at least one lower highlight grade DS. The highlight grade DS comprises one or a plurality of highlight segment DS which are used for describing the highlight segment information that forms the video summary of highlight grade. The highlight segment DS comprises a video segment sprocket bit DS which is used for describing the time information of corresponding segment interval. Additionally the highlight segment DS can comprise an image sprocket bit DS which is used for describing the representative image information of corresponding segment, a sound sprocket bit DS which is used for describing the representative sound information, and an audio segment sprocket bit DS which is used for describing the audio segment information which forms the audio summary.
