Abstract
The function of radar image recording in VDR (Voyage Data Recorder) installed on a ship has been adapted in IMO constraint regulations. For this function, a VDR should be equipped with the dedicated recording device called “Image Grabber”. Recently, as the number of radar on a ship has increased, the number of image grabber also has been increased proportionally. However this structure has lack of scalability. As a result, it could cause to rising costs and drop a competitive price. MSC.333(90) which is international standard related for VDR performances describes that both radar and ECDIS(Electronic Chart Display and Information System) image also should be store in final storage medium. And ECDIS image data should be sent through the Ethernet interface which is described in IEC 61162-450. In this paper, we proposed the technology of radar and ECDIS image processing based on Ethernet for VDR to overcome rising costs and to follow the recent trends of the data communication method.
