A study on the moving picture transmission method by railway fiber optics cable

철도 광케이블을 이용한 화상전송방안에 관한 연구

CCTV network has been implemented to transmit the image information of platfo gate and transfer section to local headquarters in the KNR(Korean National Railroa But. communication system for transferring image information around accident field has not been established yet. thus, at present implementation of communication equipment is necessary for dyn of unspecified accident to be transmitted to headquarters. Copper cable communication network is run by KNR, but it is processing installatio optics cable in connection with the implemental plan for high-speed network from n And, the capacity of communication channel will be guaranteed much more than een station and station, station and central headquarters when fiber optics cable is This study analyzes the image equipment of field for transmission and estimated m transmit image information of accident field to headquarters with using communicat ucture. And, the study considers implemental method of communication network for nce image transmission from dozens to hundreds kilometers.
