Abstract
A system and method for platform independent LOS visual information transmission is disclosed. A transmitter consists of a series of sequential images that are stacked together to form frames in a video transmission. Each image is modulated spatially, by color, and by intensity. The data is transmitted over an LOS visual channel. The receiver first captures each individual image from the received video, and then demodulates each image in the three areas it was modulated spatially, by color, and by intensity. LOS visual information transmission allows for secure data transfer and reduces interference from other applications.
