Abstract
Upon a reception of a request for connection from a terminal unit, a server sends a start menu screen for video selection. A video selection range is narrowed by changing menu screens. When a certain menu screen is reached, a history table is accessed to read frequencies of use of a plurality of corresponding videos. Heading parts of frequently used videos are sent to the terminal unit, where they are stored in a terminal memory. With a final selection of a video, its heading part is read from the terminal memory, to be reproduced. A desired video quickly starts. The remaining part of the video is sent from the server.
