Abstract
The video retrieving method provides a video retrieval man-machine interface which visually specifies a desired video out of many stored videos by using previously linked picture data corresponding to the videos. Also, a video reproduction operating man-machine interface visually designates the position of reproduction out of the picture group indicative of the contents. The video retrieving method employs video data, character information linked to the video data, picture data linked to the videos, and time information corresponding to the picture data in the video data. The character information is composed of a title of each video and a creation date thereof. The picture data include, as retrieval information, one picture data representing the content of the relevant video (one picture expressing the video, i.e., a leaflet or the like), and a plurality of picture data adapted to grasp the contents of the entire video. The time information indicates the temporal position of the picture data in the video data.
