An apparatus for protecting crosstalk of an image display device using a wireless microphone is provided to detect on/off determination of the microphone accurately, not only using an RSSI(Received Signal Strength Input) value variable according to the external environment. A wireless microphone(100) modulates a received voice signal and generates an ID(IDentification) of a device, and then transmits the modulated voice signal and the ID at the same time. An image display device(200) controls to output the voice signal received through the wireless microphone according to the predetermined condition by receiving the ID transmitted through the wireless microphone. |
