PVLC (Pixel-level Visible Light Communication) is a method that can embed human-imperceptible metadata in projected images with high-speed flickering. A significant advantage of the method is that no displacement or offset problems occur without a separate position measurement step. However, previous projection systems utilize PVLC can update neither invisible data nor visible images in real time due to its technical limitation. To solve this problem, we propose RPVLC (Reconfigurable Pixel-level Visible Light Communication) system that can update the data and the images dynamically, reconfigure the trade-off between image frame rate and image resolution, and control full color LED light source. In this paper, RPVLC system design, method, implementation, and its performance evaluations are detailed.
