# 광고 ID 장식
<a name="ad-id-decoration"></a>

AWS Elemental MediaTailor 는 콘텐츠에서 광고 시간으로 전환할 때 서버 측 광고 스티칭을 수행합니다. MediaTailor는 스티칭된 광고와 연결된 메타데이터로 매니페스트를 조건을 지정할 수 있습니다. 이렇게 하면 다음과 같은 이점이 있습니다.

**중요**  
헤더를 채우는 필드는 캐시 가능한 매니페스트가 처음 작성될 때가 아니라 광고 재생 중에 자산 목록을 가져올 때`X-AD-CREATIVE-SIGNALING `만 알려져 있기 때문에 Ad-ID 장식은 서버 가이드 광고 삽입(SGAI) 방법과 호환되지 않습니다.
+ *비디오 시작 시간*(VST) 개선
+ MediaTailor는 서버 측 광고 삽입 및 서버 안내 광고 삽입의 하이브리드 모델을 지원할 수 있습니다.
+ 서버 측 세션은 광고 위치 마커를 사용하여 재생 타임라인을 구축할 수 있습니다.
+ MediaTailor API를 사용하여 재생 타임라인을 이미 빌드한 클라이언트 측 세션의 경우 세션이 타임라인을 빌드하기 위해 추적 API를 호출하는 데 의존하지 않으므로 세션 VST가 개선됩니다.
+ 서버 측 광고 삽입과 장면에 표시되는 클라이언트 측 렌더링 광고에 MediaTailor를 활용할 수 있습니다. 이렇게 하면 플레이어의 소프트웨어 개발 키트(SDK)가 클라이언트 측 광고를 위해 광고 제공 엔터티를 직접 호출하기 위해 별도의 통합을 가질 필요가 없습니다. MediaTailor는 매니페스트와 클라이언트 측 추적 API를 통해 광고를 판매할 수 있습니다.

각 크리에이티브 광고 자산을 고유 식별자와 연결하는 표준이 있습니다. 이 연결을 통해 광고주, 기관, 공급업체 및 게시자는 독립적인 워크플로에서 창의적인 광고 자산을 연결할 수 있습니다. 스트림의 지표와 모니터링이 계속 개선되고 더 많은 배포자가 서버 기반 삽입 아키텍처를 활용함에 따라 개인화된 매니페스트 내에서와 같이 인터리브/스티치 프레젠테이션 내에서 개별 크리에이티브 자산에 할당된 식별자를 정확하게 전달해야 합니다.

# 세션에 대한 광고 ID 신호 활성화
<a name="ad-id-session-state"></a>

광고 ID 신호 기능은 세션 초기화 중에 활성화해야 합니다. 기능을 활성화하는 프로세스는 HLS/DASH 재생 접두사(암시적 세션 초기화)를 사용하여 세션을 생성하는 것과 세션 초기화 접두사(명시적 세션 초기화)를 사용하는 것과 다릅니다.

**HLS/DASH 재생 접두사를 사용하여 세션에 대한 광고 ID를 활성화하려면**
+ 플레이어에서 프로토콜에 따라 다음 형식 중 하나의 요청을 사용하여 새 MediaTailor 재생 세션을 초기화합니다.
  + 예: HLS 형식

    ```
    GET <mediatailorURL>/v1/master/<hashed-account-id>/<origin-id>/<asset-id>?aws.adSignalingEnabled=true
    ```
  + 예: DASH 형식

    ```
    GET <mediatailorURL>/v1/dash/<hashed-account-id>/<origin-id>/<asset-id>?aws.adSignalingEnabled=true
    ```

**세션 초기화 접두사를 사용하여 세션에 대한 광고 ID를 활성화하려면**
+ 플레이어에서 MediaTailor에 대한 세션 초기화 요청에 대한 JSON 메시지 본문을 구성합니다.
  + `adsParams` 객체 내에서 MediaTailor가 ADS에 전달해야 하는 파라미터를 제공합니다. 이러한 파라미터는 MediaTailor 구성의 ADS 템플릿 URL에 있는 `[player_params.param]` 설정에 해당합니다.
  + 광고 ID 신호를 활성화하려면 `adSignaling` 객체를 최상위 객체로 추가하고 내부에 `enabled` 및 값 이라는 파라미터를 추가합니다`true`. 기본`adSignaling`값은 입니다`disabled`.
  + 예: HLS 형식

    ```
    POST master.m3u8
        {
           "adsParams": {
               "deviceType": "ipad"
           },
           "adSignaling": {
               "enabled": "true"
           },
           "reportingMode": "client"
        }
    ```
  + 예: DASH 형식

    ```
    POST manifest.mpd
        {
            "adsParams": {
               "deviceType": "ipad"
           },
           "adSignaling": {
                "enabled": "true"
            },
            "reportingMode": "client"
        }
    ```

# 매니페스트 및 광고 메타데이터 삽입
<a name="ad-id-manifest"></a>

광고 스티칭 프로세스 중에 MediaTailor는 스티칭되는 각 크리에이티브와 연결된 고유 ID를 매니페스트에 추가합니다. MediaTailor는 VAST 응답에서 해당 크리에이티브의 `id` 속성 값에서 크리에이티브의 고유 ID를 가져옵니다. 크리에이티브에 ID 속성 값이 없는 경우 MediaTailor는 빈 값()을 게시합니다`id=""`.

MediaTailor는 매니페스트 내 메타데이터 신호를 사용하여 광고 크리에이티브 메타데이터를 위한 클라이언트 추적 API와 전체 타임라인 내의 타이밍/위치 지정 간의 종속성을 분리합니다. 이 연결 해제는 재생을 초기화하기 전에 플레이어의 사용자 인터페이스(UI)가 타임라인의 광고 중단 위치를 렌더링하는 재생 지연 시간을 줄입니다(특히 VOD 시나리오에서).

추가된 메타데이터의 형식은 다음과 같습니다.
+ HLS 매니페스트의 경우 추가된 메타데이터는 가용 기간 동안 각 광고에 대한 `DATERANGE` 태그의 형태를 취합니다.
+ DASH 매니페스트의 경우 추가된 메타데이터는 각 광고 기간 내에 `Event` 요소의 형태를 취합니다.

다음 JSON 메시지 본문은 VAST 응답의 예를 보여줍니다.

```
{
  "version": 1,
  "identifiers": [
    {
      "scheme": "urn:smpte:ul:060E2B34.01040101.01200900.00000000",
      "value": "creativeId",
      "ad_position": "adId",
      "ad_type": "adType",
      "tracking_uri": "trackingUri",
      "custom_vast_data":"customVastData"
    }
  ]
}
```

이전 예제에서:
+ *creativeId*는 광고에 대한 `Creative` 요소의 `Id` 속성 값입니다.
+ *adId*는 광고의 시작과 연결된 HLS 시퀀스 번호 또는 광고의 DASH 기간 ID입니다.
+ *adType*은 VAST 응답을 `overlay`기반으로 `avail` 또는 입니다.
+ *trackingUri*는 MediaTailor 세션의 상대 추적 엔드포인트로, 형식입니다. `../../../../tracking/hashed-account-id/origin-id/session-id` 
+ *customVastData*는 MediaTailor가 `creative_signaling` VAST 확장에서 추출하는 값입니다. MediaTailor는 CDATA 노드가 있는 경우 해당 노드의 콘텐츠를 사용합니다. 자세한 내용과 샘플 VAST 응답은 [Ad Decision Server(ADS) 상호 작용](ad-id-ads-interactions.md) 섹션을 참조하세요.

# 광고 메타데이터를 사용하여 HLS 매니페스트 개인화
<a name="ad-id-manifest-hls"></a>

라이브 HLS 스트림의 경우 MediaTailor는 스트림에 `PROGRAM-DATA-TIME` 태그가 포함된 경우에만 매니페스트 기간당 한 번 이상 메타데이터를 추가합니다. 온디맨드 비디오(VOD) 스트림의 경우 MediaTailor는 개인화된 매니페스트에서 하나 이상의 세그먼트`PROGRAM-DATE-TIME`에를 추가합니다. 여기서 각 VOD 자산의 시작 시간은 에포크 0()입니다`1970-01-01T00:00:00Z`. 오리진 매니페스트에 기존 `PROGRAM-DATE-TIME` 콘텐츠가 있는 경우 MediaTailor는 해당 콘텐츠를 보존합니다.

MediaTailor는 광고 결정 서버(ADS)에서 반환한 크리에이티브로 매니페스트를 개인화합니다. 각 광고에 대해 MediaTailor에는 광고 기간에 걸친 `DATERANGE` 태그도 포함되어 있습니다. `DATERANGE` 태그 형식은 *SVA 기술 간행물* 2023 버전의 [DASH 및 HLS의 광고 크리에이티브 신호](https://www.svta.org/document/draft-ad-creative-signaling-in-dash-and-hls/) 섹션에 설명된 것과 유사합니다.

MediaTailor`DATERANGE`가 생성하는 에는 고유한 ID 값이 있습니다. 고유성을 보장하기 위해([SCTE-35를 EXT-X-DATERANGE로 매핑](https://datatracker.ietf.org/doc/html/draft-pantos-http-live-streaming-23#section-4.3.2.7.1)에 지정된 지침에 따라) MediaTailor는 가용 구간의 *첫 번째* 광고 세그먼트 `MEDIA-SEQUENCE` 수를 가용 구간 내의 광고 시퀀스 번호와 결합합니다.

슬레이트가 활성화된 구성에서 과소 채워진 광고 시간의 경우 MediaTailor는 `DISCONTINUITY` 태그로 구분되지만 `DATERANGE` 메타데이터 없이 슬레이트 세그먼트를 가용 구간 끝에 추가합니다.

맞춤형 매니페스트에 연결된 각 광고에 대해 MediaTailor는 사용자 지정 `DATERANGE` 태그에 base64로 인코딩된 데이터로 표시되는 창의적인 메타데이터를 추가합니다.

MediaTailor`PROGRAM-DATE-TIME`는 광고 위치를 나타내는 HLS `DATERANGE` 요소의 앵커로 사용하기 위해 VOD 매니페스트에를 추가합니다.  
MediaTailor`DATERANGE`가 생성하는 에는 고유한 ID 값이 있습니다. 고유성을 보장하기 위해([SCTE-35를 EXT-X-DATERANGE로 매핑](https://datatracker.ietf.org/doc/html/draft-pantos-http-live-streaming-23#section-4.3.2.7.1)에 지정된 지침에 따라) MediaTailor는 가용 구간의 *첫 번째* 광고 세그먼트 `MEDIA-SEQUENCE` 수를 가용 구간 내의 광고 시퀀스 번호와 결합합니다.  
다음 예제에서 MediaTailor는 `MEDIA-SEQUENCE` 421을 광고 위치 번호와 연결합니다.

# 광고 메타데이터를 사용하여 DASH 매니페스트 개인화
<a name="ad-id-manifest-dash"></a>

MediaTailor는 광고 결정 서버(ADS)에서 반환한 크리에이티브로 매니페스트를 개인화합니다. 각 광고에 대해 MediaTailor에는 광고 기간에 걸친 `EventStream` 요소도 포함됩니다. `Event` 요소 형식은 *SVA 기술 간행물* 2023 버전의 [DASH 및 HLS의 광고 크리에이티브 신호](https://www.svta.org/document/draft-ad-creative-signaling-in-dash-and-hls/) 섹션에 설명된 형식과 유사합니다.

슬레이트가 활성화된 구성에서 과소 채워진 광고 시간의 경우 MediaTailor는 슬레이트 기간을 가용 기간 종료에 추가하지만 `EventStream` 메타데이터는 추가하지 않습니다.

개인화된 매니페스트에 연결된 각 광고에 대해 MediaTailor는 `Event` 요소 내에 `CDATA` 요소로 표시되는 창의적인 메타데이터를 추가합니다.

# Ad Decision Server(ADS) 상호 작용

MediaTailor는 VAST 응답의 크리에이티브 `id` 속성 값을 광고 ID 신호의 값으로 사용합니다. `id` 속성 값이 비어 있거나 VAST 응답에 없는 경우 MediaTailor는 광고 ID 신호에 빈 값을 배치합니다.

**Example VAST 응답:**  
다음 샘플 VAST 응답에는 인라인 선형에 대한 `id` 속성 값이 포함됩니다`Creative`. MediaTailor는 사용자 지정 VAST `Extension` 요소에서 값을 추출하고 매니페스트의 크리에이티브 메타데이터에 해당 값을 배치합니다.
