초록

본고에서는 MPEG에서 설계하여 ISO 표준화한 실시간/저지연 미디어 전송 기술인 MMT (MPEG Media Transport) 에 대해 알아본다. MMT는 인터넷 환경과 통합된 차세대 방송 시스템에의 적용을 목표로 설계된 기술로, IP 기반 전송 프로토콜의 사용과 HTML5 기반 서비스 제공을 가정하여 MPEG2-TS의 장점을 계승하면서 이종망 및 다기기 서비스의 지원을 고려하여 설계 되었다. 따라서 MMT는 고품질의 UHD TV서비스를 안정적으로 제공함과 동시에 인터넷 활용 부가 서비스 제공을 목적으로 하는 차세대 지상파 방송에 있어 최적화된 표준 기술이라 할 수 있다.
