The Image Communication with a Personal Computer on Voice Line of the INMARSAT

摘要

For the present time, an image communication is sending weather charts, fishing charts and presses etc. to a maritime mobile station from a land station by a facsimile with short wave. But it is low level image, that can not send it to the land station from maritime mobile station. So, we had experimented between a ship station and a land station to send high resolution mode image of 640 X 400 dots with a personal computer on voice line of the International Maritime Satellite (INMARSAT). As a result of the experiments, we could send an images for effective average speed about 7,200 bps to the Nagasaki land station from the ship station of T/S Nagasakimaru. Similarly, we could receive it from the land station.
