This study is a study dealing with the empirical test of standardized multimedia disaster warning broadcasting linked with the next-generation prediction and warning platform and the disaster warning additional data service of terrestrial UHD broadcasting. The next-generation prediction and warning platform used in the demonstration test complies with the CAP-based TTA standardization standard, and the UHD disaster warning additional data service complies with the AEAT standard. As a result of the experiment, when a standardized CAP disaster warning message is issued and delivered to a broadcasting company, a system was established so that it is automatically converted to AEAT, a UHD disaster warning additional data message, and transmitted. The receiver unit was configured by connecting a set-top capable of receiving disaster alert data and a TV with an HDMI cable. When a disaster is announced, the set-top displays the AEAT message on the TV broadcasting screen, customized to the priority of the disaster and the area where it is issued. In addition, incoming messages are displayed in a language suitable for user settings among 5 languages. Additional multimedia functions such as images and alarm sounds could also be linked. In particular, it was confirmed that the receiver message was displayed within 3 seconds of issuing the disaster alert, enabling prompt delivery of the disaster alert.

이 연구에서는 현 재난 경보에서 재난 약자가 가질 수 있는 취약성에 대해 알아보았다. 그리고 해당 취약성에 대한 해결 방안과 해결을 위해 적용할 수 있는 기술적 요구사항도 함께 알아보았다. 재난 약자는 경보 수신 공백, 맞춤형 서비스 부족, 단독 대응 불가 등과 같은 공통적 재난 경보 취약성과 함께 어린이, 노인, 외국인, 장애인 집단 별로 차별적 취약성을 가지는 것으로 나타났다. 이를 보완하기 위해서는 단말기에 이동통신 수신 모듈과 ATSC 3.0 수신 모듈 모두 탑재, ATSC 3.0 방송망을 통해 재난 약자 유형에 맞춘 복수의 메시지 전송, 단말기의 수신자 프로파일 설정에 의한 메시지 표출, 기존의 AEAT 개선 등이 공통적으로 필요하다. 그리고 어린이, 노인, 외국인, 장애인 집단 별로 차별적 취약성을 보완할 수 있는 차별적 기술도 필요하다.

In this paper, we simulated disaster broadcast service using terrestrial UHD additional data. We looked at nine functions(warning alarm, location-based information, multilingual, re-viewing the title of breaking news, evacuation knack video, CCTV, clip video, wake up, automatic channel switching) by referring to ATSC 3.0 standards. Analyzing the advantages and problems of the proposed disaster broadcast. Expert interviews were conducted after a demonstration and explanation of terrestrial UHD disaster broadcast. They said that the problems with the technology were difficulty in using, obstruction of viewing, content creation problems, and problems with advertisers. In addition to the lack of simulation-based research, this research has provided an insight into the technology by showing it in a visible way. This helped shape the advantages and problems of technology.
