13FR1800, 부가데이터 송수신 기술을 이용한 지상파방송망 관리 시스템 개발,
Heung Mook Kim
Abstract
□ 개발목표 계 획 추가적인 주파수 할당 없이 방송망관리 정보를 방송채널을 통해 부가적으로 송수신함으로써 지상파방송망을 원격으로 모니터링하고 제어할 수 있는 지상파방송망 관리시스템 개발 실 적 방송망 모니터링 및 수집장치, 방송망 관리정보 분석기/추출기를 포함한 지상파방송망 관리시스템 개발 완료
□ 기대효과 기존의 DTV 방송 서비스에 영향을 주지 않으면서 동일한 채널에 부가 데이터를 추가로 전송하는 기술로써 국가적으로 문제가 되고 있는 주파수 자원 부족문제에 대응하고, 개발된 기술을 이용하여 방송국 중계기 관리 및 방송 서비스 품질관리 비용을 획기적으로 줄일 수 있음
□ 적용분야 기 구축되어 있는 지상파 방송시설을 활용하는 방식으로 부가데이터를 위한 장비의 추가 설치만으로 방송망 관리가 가능하므로 비용 절감 뿐만 아니라 전국적인 인프라를 갖추고 있는 방송망에서 부가데이터를 활용한 새로운 서비스 개발 가능
