Eureka-147 DAB(Digital Audio Broadcasting) 시스템[1]은 이미 유럽에서 이동수신 성능이 보장된 시스템으로써 오디오 서비스를 기본으로 제공하고 여기에 파일 및 스트림 형태의 멀티미디어 데이터를 추가로 전송할 수 있는 시스템이다. 지상파 DMB(Digital Multimedia Broadcasting)는 스트림 형태의 멀티미디어 데이터를 전송할 수 있는 Eureka-147 DAB 시스템을 특성을 이용하여 이동 환경에서 안정된 비디오 동영상 서비스를 제공할 목적으로 개발되었다. 반면에 본 논문에서는 Eureka-147 DAB 시스템의 이러한 특징을 기반으로 단말 플랫폼에 무관하게 파일 형태의 다양한 데이터 서비스를 가장 효율적으로 제공할 수 있는 현재 국내 및 국제 표준화가 추진중인 지상파 DMB 미들웨어 표준에 대해 소개하고자 한다.
