<p>A main-part video (vdt) and thumbnail image (sdt) read from a receiving section (C10) are recorded on a large capacity storage medium (M1), and metainformation (mdt) is recorded on a high-speed storage (C12). According to the metainformation (mdt), a semantic browsing means (C1) extracts partial video from the main-part video, editing preview video. Furthermore, according to the metainformation (mdt), a semantic graph and the current position are displayed on the screen. If a position specifying input occurs, the main-part video or preview video is reproduced from the specified position. If a browsing specification input occurs, the semantic browsing means (C1) browses both a main-part and its preview video, and browses a main-part video only or a preview video only. The charging section (C18) performs the charging.</p> |
