Ship Dynamic and Video Monitoring System at Sea

Ship dynamic and video monitoring system at sea aims at improving safety of ship sailing and providing help for salvage. In this system, wireless communication technology of CDMA1X is used to transfer GPS dynamic positioning information and ship video. As to the special communications at sea, the actual bandwidth of single channel CDMA1X is too low to transfer video. In order to cope with this problem, this paper proposes scalable video delivery framework and uses CDMA1X multi-channel binding technology. The scalable video delivery framework is put forward to meet the requirement of complex network environment at sea. CDMA1X multi-channel binding technology is used to increase bandwidth and meet the quality requirement of video image. This paper describes the design and implementation of this system. In the circumstance of binding four CDMA1X channels, image transfer quality is perfect enough to meet the requirements of nearshore ship monitoring. This system also can adapt itself to different network bandwidths.
