Abstract

Republic of Korea has established 'Transmission and Reception for Terrestrial UHDTV Broadcasting Service' standard based on ATSC 3.0, the next-generation broadcasting standard in North America and is now providing commercial services. Republic of Korea has been studying terrestrial UHDTV based disaster broadcasting service using the ATSC 3.0 AEA system's technology since 2018. ATSC 3.0 has established a standard for expanding disaster broadcasting services, which were used to be simple push-type text message broadcasting, by introducing bidirectional and rich-media transporting mechanisms. However, the disaster information is still focused on the general public, and disaster broadcasting service including detailed information for the vulnerable are still insufficient. In this paper, we proposed the optimized disaster broadcasting service for vulnerable populations based on ATSC 3.0 after defined the disaster vulnerable populations as the target of the service. And we defined the extension element of disaster broadcasting message for service provision. The proposed service can be an effective means to increase the possibility of disaster information reception and evacuation to vulnerable populations. In addition, it is expected to be used as a basic research for development of diverse and effective advanced services for vulnerable populations through linkage with existing disaster alerting and countermeasures studies.

현재 우리나라는 북미의 차세대 방송 표준인 ATSC 3.0을 기반으로 국내 지상파 UHD 방송 표준을 제정하고 상용 서비스를 제공하고 있으며, ATSC 3.0에 정의된 재난경보전달을 위한 AEA 시스템 재난방송기술을 이용해 2018년부터 지상파 UHDTV 방송망을 활용한 재난경보방송서비스에 관한 연구를 진행하고 있다. ATSC 3.0이 기존에 단순 푸쉬 형태의 텍스트 메시지 전송에 그치던 재난방송 서비스를 양방향성과 리치미디어의 전송 메카니즘을 도입함으로써 진보된 재난방송 서비스로 확장할 수 있는 표준을 마련하였지만 아직 재난 정보 전달은 여전히 일반 대중들을 중심으로 한 내용이 대부분으로, 구체적인 재난약자를 위한 재난 정보 전달 및 대응책은 미흡한 실정이다. 이에 본 논문에서는 재난방송서비스 수신 대상으로서의 재난약자를 정의하여 ATSC 3.0 기반 재난약자 맞춤형 재난방송서비스를 제시하고, 서비스 제공을 위해서 필요한 재난방송메시지 확장 엘리먼트를 정의한다. 제안하는 재난약자 맞춤형 서비스는 재난약자들을 대상으로 하는 재난 정보 전달 가능성을 높이고 재난 상황에 대한 대처를 유도할 수 있는 보조적인 수단이 될 수 있다. 또한, 기존 재난경보알림 및 재난대응 연구들과 연계를 통해 재난약자를 위한 다양하고 실효성 있는 응용서비스 개발의 기초 연구로 활용될 것으로 예상된다.
