| Summary |
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. |
