The mainstream of conventional underwater radio communication technology is acoustic communication; however, there is a problem in that the communication speed is limited. On the other hand, optical wireless communication technology has been utilized, wherein in which large capacity data transmission becomes possible. In this paper, we show the configuration of the transmitter and receiver for FPGA mounted video and its evaluation results for video transmission by underwater visible light communication. As a result of the evaluation, it is shown that a transmission speed of 20Mbps or more can be achieved, and the total power consumption of the visible light communication transceiver was at most 0.372W.
