ATSC 3.0 방송게이트웨이는 원격의 송신소에 설치된 다수의 송신기들(transmitters)과의 안정된 통신 링크(광케이블, M/W, 위성 등)을 통해 방송 미디어 패킷 스트림을 내보낸다. ATSC 3.0 표준에서는 방송 게이트웨이와 송신기 간 STL (Studio to Transmitter Link) 구간에 STLTP (STL Transport Protocol)를 정의하고, 멀티캐스트 구조 내에 IP 터널링(Tunneling) 형태로서 BB 프레임과 L1 시그널링 정보, 시간 정보를 싣도록 한다. 본 논문에서는 ATSC 3.0 기반의 방송 게이트웨이의 주요 기능 역할로서 단일주파수망(SFN)을 위한 패킷 스트림 구성 및 이를 위한 기능 구조에 대해 기술한다.
