PURPOSE: An online education system is provided to make a separated specific device output sound signals of at least one character helping a user to listen a lecture so that it can prevent a dull and boring lecture. CONSTITUTION: The system comprises an education contents management server(30), a user computer(10), a signal transmitter(40) and a signal receiver(50). The education contents management server(30) receives an education select request signal from a user, searches for the requested education contents in a database, and transmits the searched contents to the user computer(10). The user computer(10) executes the transmitted education contents, and transmits the audio/video signals to peripherals. The signal transmitter(40) checks if pilot signals exist in the audio/video signals, outputs radio frequency in the case that the pilot signals exist, and passes the audio/video signals. The signal receiver(50), separated from the signal transmitter(40), receives the radio frequency signals, converts the radio frequency into audio signals, and amplifies the audio signals at a set level.
