초록

본 논문에서는 디지털 라디오 표준인 DRM(Digital Radio Mondiale) 및 DRM+(Digital Radio Mondiale Plus) 시스템을 이더넷모드에서 분석할 수 있는 다중화분산접속(MDI, Multiplex Distribution Interface) 분석기를 설계한다. 제안하는 MDI 분석기는 메모리 공유 기술을 가진 공통 블록 모듈을 사용하여 MDI 패킷들의 부하를 감소시키며, 차세대 디지털 라디오 방송시스템을 위해 수신된 MDI 패킷을 통해 IP(Internet Protocol)와 DRM/DRM+ 시스템의 FAC(Fast Access Channel)/SDC(Service Description Channel) 구성정보를 확인할 수 있다.

In this paper, a novel MDI(Multiplex Distribution Interface) analyzer is designed in Ethernet-mode for DRM(Digital Radio Mondiale), and DRM+(Digital Radio Mondiale Plus) systems. The proposed MDI analyzer can reduce the overload of MDI packets by using memory sharing techniques into a common module block. In consequence, it verifies the received MDI packets by composition information of IP(Internet Protocol) and FAC(Fast Access Channel)/SDC(Service Description Channel) in DRM/DRM+ systems for the next generation digital radio broadcasting systems.
