DASH 매니페스트 시간 신호 예제

DASH 시간 신호에 대한 오리진 매니페스트 예제

다음 예제는 콘텐츠 오리진DASH에서가 수신한 매니페스트의 광고 사용률을 보여줍니다. 다음 예제에서는 scte35:TimeSignal 마커를 보여줍니다:

DASH 시간 신호에 대한 개인 맞춤형 응답 예제

AWS Elemental MediaTailor 는 광고 사양으로 광고 공간을 개인화합니다. 개인화는 플레이어에서 수신되는 최종 사용자 데이터와 현재 진행 중인 광고 캠페인을 나타냅니다.

다음 예제에서는 광고 사용률을 AWS Elemental MediaTailor 개인화한 후 이를 보여줍니다.
