Summary:PURPOSE: A broadcasting retransmission device is provided to safely supply different signal which a plurality of neighboring device desires. CONSTITUTION: Broadcasting in which a demodulation unit(320) modulated is demodulated. A modulation unit(370) modulates a demodulated broadcasting in a second modulation system. A spectrum sensing unit(390) detects an available band through a spectrum sensing in an idle bandwidth. A control unit(400) retransmits the modulated broadcasting to at least one neighboring device through the detected available band.
