AUDIO TRASFER SYSTEM, APPARATUS AND METHOD

摘要

PURPOSE: An audio transmission system, a device and a method thereof are provided to seclude a carrier capable of pop noise, thereby reducing the pop noise in a receiving unit. CONSTITUTION: An audio transmitter(100) load an audio signal to an analog IR carrier. The audio transmitter transmits the analog IR carrier through IR LED(Light Emitting Diode). Before supply power about the IR LED is switched off, the audio transmitter secludes the analog IR carrier to be transmitted to the IR LED. A receiver(200) reproduces the transmitted audio signal.
