| 摘要 |
This invention has as its object to achieve a simple arrangement and cost reduction of each terminal, and allow processing of high-resolution video information. A system includes a narrow-band communication path (20) for transmitting control information, a broad-band communication path (30) for transmitting video information, a plurality of control terminals (40-1 - 40-n) connected to the narrow-band communication path (20), a plurality of display terminals (50-1 - 50-n) connected to the broad-band communication path (30), and a server (1) connected to the narrow-band communication path (20) and broad-band communication path (30). Video information is transmitted from the server (1) to one of the display terminals, and control information is transmitted from one of the control terminals to the server (1) to control transmission of video information from the server (1).
