Description
Summary:A visible light communication system for parallel transmission of high-quality audio and video signals using illumination white and red light-emitting diodes (LEDs) is presented in this paper. For video transmission, we adopts the pulse width modulation (PWM) scheme at the carrier frequency of 15 MHz, whereas for the analog audio signal, the Sony/Philips Digital standard is used. We show that successful simultaneous high-quality audio and video signal transmissions over a link span of 50 cm are possible without the need for optimized optics. For audio transmission, only the link span is doubled to 100 cm.
