광고 메타데이터를 사용하여 DASH 매니페스트 개인화
MediaTailor는 Ad Decision Server(ADS)에서 반환한 크리에이티브로 매니페스트를 개인화합니다. 각 광고에 대해 MediaTailor에는 광고 기간에 걸친 EventStream 요소도 포함되어 있습니다. Event 요소 형식은 SVA 기술 간행물의 2023 버전에서 DASH 및 HLS의 광고 크리에이티브 신호
슬레이트가 활성화된 구성에서 과소 채워진 광고 중단의 경우 MediaTailor는 슬레이트 기간을 사용 가능 기간이 끝날 때까지 추가하지만 EventStream 메타데이터는 추가하지 않습니다.
개인화된 매니페스트에 연결된 각 광고에 대해 MediaTailor는 Event 요소 내에서 CDATA 요소로 표시되는 크리에이티브 메타데이터를 추가합니다.
