PURPOSE: A transmission and reception apparatus for image/voice signal using power cable is provided to transmit image/voice signal at the same time through multiple transmission circuit and a single circuit. CONSTITUTION: A switching IC(Integrated Circuit)(2) outputs the serial signal of the voice signal and video signal. The modulation PLL(Phase Locked Loop) IC(5) modulates the serial signal. The pulse trans(pulse transformer)(6) outputs the serial signal which is modulated as described above in the alternating current. A pulse trans(11) modulates the alternating current serial signal. A first amplification unit(12) amplifies the forged serial signal as described above. A demodulation PLL IC(13) demodulates the serial signal which is amplified as described above. A second amplifier outputs the serial signal which is demodulated as described above to a monitor(15) and a speaker(16).
