PURPOSE: To suppress the increment of installation cost, maintenance cost, etc., by using a display for video signals and pictures from a computer in common. CONSTITUTION: The education system is constituted of a master console 2 provided with an instruction computer 1 and slave consoles 5-1 to 5-n provided with their exclusive computers 3 and displays 4. A display capable of displaying a picture signal inputted from the computer 3 and a video signal with a base band is used as the display 4 and each slave console is provided with a selection means 6 capable of selecting a picture based upon a video signal selectively sent from an instructor and a picture obtained from the master console 2 or other slave consoles 5 and selectively displaying the picture based upon the video signal or the picture from the master console 2 or the slave consoles 5 on the display 4. Consequently a computer picture outputted from the computer 1 of the master console 2 can surely be transmitted to all the slave consoles 5-1 to 5-n by the simple system constitution and the cost of the system can be reduced. |
