Terrestrial Digital TV Relay Transmission Construction by Using Optoelectronic Techniques

광전변환기술을 이용한 Digital TV 중계전송 구성방안

This paper describes a study of terrestrial digital TV transmission systems using wideband opto-electronic techniques such as electro-absorption modulators, wavelength division multiplex to support cost effective, high speed, flexible and interactive digital TV networks including ultra-high speed subscriber networks. In particular, the national DTV networks to be installed is required huge amount of cost. Therefore, the network should be carefully designed for DTV, communication and multimedia services in the future. In this paper, wideband optoelectronic DTV systems are suggested.

본 논문은 지상파TV방송이 디지털방식으로 전환함에 있어 기존의 무선을 이용 한 DTV중계 전송망을 광전변환을 이용한 유선망으로 전송하는 방안을 제작과 실험을 통하여 전송로의 구조적 전기적 특성과 방송망으로서의 적용 가능성을 연구하였다.
