Video reproduction device

Abstract

The present invention relates to a technique for displaying a characteristic image or scene of video data as a thumbnail so that a user can easily understand the contents of the video data. Video data is inputted, the data describing an important scene in the video data is inputted or generated, and a thumbnail of the important scene indicated in the important scene data is generated. The inputted video data is reproduced, the reproduced video and the thumbnail are displayed, and the important scene in the video data is displayed in a thumbnail. Alternatively, an image at an arbitrary position of the important scene or at the beginning or at a position where an audio data power is at its peak is made a thumbnail image and a thumbnail image is generated from the important scene in the video data for display.
