PURPOSE: A multimedia system for education is provided to simply perform an installation and maintenance work, and promote the class participation from a student by making a teacher PC control a student PC more powerfully. CONSTITUTION: A teacher control box(30) receives a video/audio signal from the teacher computer(10) and transmits the video/audio signal to the student computer(20). A selection button(32) selects a class mode or a self-control learning mode by installing to the teacher control box. One terminal of a student control box(40) sequentially connects to the teacher control box through a daisy chain method and another terminal connects to each student computer. The student control box selectively outputs the input from the teacher control box and the student. If the class mode is selected, the student control box restricts an input signal from a PC main body(21) and a keyboard(23) of the student PC, and outputs the video/audio signal inputted from the teacher control box to a monitor(22) and a speaker or a headset(24).
