최근 다양한 국제 방송표준에서 차세대 오디오 코덱의 하나로 MPEG-H 3DA(3D Audio)가 채택되었으며, 이를 활용한 몰입형 오디오 서비스들이 개발되고 있다. 이러한 몰입형 서비스를 원활히 제공하기 위해서는 표준에 정의된 기술을 구현한 제품간의 상호호환성 검증이 필수적으로 추진되어야 하며, 이를 위해 개발된 MPEG-H TV Audio System 인증 프로그램에 대해 대상 제품과 시험서비스의 구조에 대해 설명하고 있다.

Due to the large-scale TV display, the convergence of broadcasting and broadband, and the advancement of signal compression and transmission technology, terrestrial digital broadcasting has evolved into UHD broadcasting capable of providing simultaneous broadcasting of fixed UHD and mobile HD. The Korean standard for terrestrial UHDTV broadcasting is based on ATSC 3.0, the broadcasting standard of North America. The terrestrial UHDTV broadcasting standard chose that as a new AV codec standard, HEVC video codec which can compress with higher efficiency compared to AVC, and MPEG-H 3D audio codec for realistic audio. Also, DASH and MMT are adopted as transmission format instead of MPEG-2 TS to support broadband as well as broadcasting network, and in order to provide 4K UHD/mobile HD service simultaneously ROUTE multiplexing technology is applied. In this paper, we propose an audio/video encoder, which is required to provide HDR/WCG supported high quality video service, 10.2 channel/4 object supporting stereo sound service, fixed UHD and mobile HD simultaneous broadcasting service based on ATSC3.0, also we implemented the ATSC 3.0 LDM system for ROUTE/DASH packager, multiplexing system and physical layer transmission/reception, and verified the service ability by applying it to real time broadcast environment.
