A visible light communication to transmit high quality video and audio signal was demonstrated by using illumination LEDs. In the transmitter, by using ultra high speed comparator, the analog video signal was modulated to 15 MHz pulse width modulation (PWM) signal. The analog audio signal was analog-to-digital converted with 192 KHz sampling rate, 24 bits resolution. The video and audio signals are transmitted using the illumination LED transmitter. In the receiver, a photodiode senses the optical signals transmitted from the LED transmitter and the received electrical signal is amplified. And then, the digital signals are recovered. The digital signals are converted into analog signal. Due to the digital transmission based on visible light from the illumination LED, the high-quality video and audio signal transmission is performed.
