Overlaying a motion video with data information for digital signage and image-sensor-based visible light communication systems

抄録

A digital signage image-sensor-based visible light communication (IS-VLC) system can transmit data information by embedding it on visual information. The use of a motion video as visual information makes it difficult to completely erase the visual information in this system. The extraction of data information is an important issue because the incomplete extraction will degrade the bit error rate performance. In this letter, we expand the IS-VLC system to overlay a motion video with data information by introducing a cell-position correction method and a noise elimination method. Experimental results clarify the effectiveness of the extended system.
