Abstract

In a mobile consumption environment, users not only desire to preview video contents with highlights, but also desire to consume attractive segments of the video rather than the whole video. Thus, condensed representation of video contents which can represent the whole video content and video structure is demanded. In this paper, we propose a video content authoring system allowing content authors to filter the video structure and to compose contents and metadata efficiently and effectively. The proposed authoring system consists of two modules: video analyzer and metadata generator. A video analyzer detects shot boundaries and scenes and establishes temporal segmentation metadata including shot and scene boundary information. The shot detection adopts adaptive thresholding with different multiple windows to segment the raw video into shots. The segmented shots are grouped and merged depending on similarity between adjacent shots. In order to minimize the consumption time of the shot clustering, we apply a span as a computation unit, which is defined as aggression of successive shots. A metadata generator allows authors to edit the video metadata in addition to temporal segmentation metadata which is detected by a video analyzer. The video metadata supports hierarchical representation of individual shot and scene.
