# Insertion de manifestes et de métadonnées publicitaires
<a name="ad-id-manifest"></a>

Au cours du processus d'assemblage des publicités, MediaTailor ajoute au manifeste l'identifiant unique associé à chaque création en cours de montage. MediaTailor obtient l'identifiant unique de la création à partir de la valeur d'`id`attribut de cette création dans la réponse VAST. Si la création ne possède pas de valeur d'attribut ID, elle MediaTailor publiera une valeur vide (`id=""`).

MediaTailor utilise un signal de métadonnées intégré au manifeste pour dissocier les dépendances entre l'API de suivi client pour les métadonnées de création publicitaire et timing/positioning dans le calendrier global. Ce découplage réduit la latence de lecture (en particulier dans les scénarios de VOD), où l'interface utilisateur (UI) du lecteur affiche les positions des pauses publicitaires dans la chronologie avant d'initialiser la lecture.

Les métadonnées ajoutées prennent les formes suivantes :
+ Pour les manifestes HLS, les métadonnées ajoutées prennent la forme de `DATERANGE` balises pour chaque annonce pendant la période de disponibilité.
+ Pour les manifestes DASH, les métadonnées ajoutées prennent la forme d'un `Event` élément au sein de chaque période publicitaire.

Le corps du message JSON suivant montre un exemple de réponse VAST :

```
{
  "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"
    }
  ]
}
```

Dans l'exemple précédent :
+ *creativeId*est la valeur d'`Id`attribut de l'`Creative`élément de l'annonce
+ *adId*est soit le numéro de séquence HLS associé au début de l'annonce, soit l'identifiant de période DASH de l'annonce
+ *adType*est soit`overlay`, `avail` soit, sur la base de la réponse VAST
+ *trackingUri*est le point de terminaison de suivi relatif pour la MediaTailor session, au format `../../../../tracking/hashed-account-id/origin-id/session-id`
+ *customVastData*est une valeur MediaTailor extraite de l'extension `creative_signaling` VAST. MediaTailor utilise le contenu du nœud CDATA, s'il est présent. Consultez la [Interactions avec le serveur de décision publicitaire (ADS)](ad-id-ads-interactions.md) section pour plus de détails et un exemple de réponse VAST.

# Personnalisation des manifestes HLS avec des métadonnées publicitaires
<a name="ad-id-manifest-hls"></a>

Pour un flux HLS en direct, ajoute des métadonnées MediaTailor uniquement lorsque le flux contient des `PROGRAM-DATA-TIME` balises, au moins une fois par durée de manifeste. Pour un flux de vidéo à la demande (VOD), MediaTailor ajoute `PROGRAM-DATE-TIME` au moins un segment dans le manifeste personnalisé, où l'heure de début de chaque ressource VOD est Epoch Zero (). `1970-01-01T00:00:00Z` Si le manifeste d'origine possède un `PROGRAM-DATE-TIME` contenu existant, il MediaTailor préserve ce contenu.

MediaTailor personnalise le manifeste avec les créations renvoyées par le serveur de décision publicitaire (ADS). Pour chaque annonce, inclut MediaTailor également un `DATERANGE` tag qui couvre la durée de l'annonce. Le format des `DATERANGE` balises est similaire à celui décrit dans la section [Signalisation publicitaire créative dans DASH et HLS](https://www.svta.org/document/draft-ad-creative-signaling-in-dash-and-hls/) de la version 2023 de la publication *technique de la SVA*.

Le `DATERANGE` qui MediaTailor génère possède des valeurs d'identification uniques. Pour garantir l'unicité (conformément aux directives spécifiées dans [Mapping SCTE-35 into EXT-X-DATERANGE](https://datatracker.ietf.org/doc/html/draft-pantos-http-live-streaming-23#section-4.3.2.7.1)), MediaTailor associe le `MEDIA-SEQUENCE` numéro du *premier* segment publicitaire de l'annonce au numéro de séquence de l'annonce contenue dans la publication.

Pour les pauses publicitaires insuffisamment remplies dans les configurations dans lesquelles Slate est activée MediaTailor , ajoutez les segments de Slate à la fin de la publication, séparés par une `DISCONTINUITY` balise, mais sans aucune métadonnée. `DATERANGE`

Pour chaque annonce insérée dans le manifeste personnalisé, les métadonnées créatives sont MediaTailor ajoutées, représentées sous forme de données codées en base64 dans une balise personnalisée. `DATERANGE`

**Example Manifeste personnalisé VOD HLS :**  
MediaTailor `PROGRAM-DATE-TIME`s'ajoute aux manifestes de VOD afin de les utiliser comme points d'ancrage pour les `DATERANGE` éléments HLS qui indiquent les positions des annonces.  
Le `DATERANGE` qui MediaTailor génère possède des valeurs d'identification uniques. Pour garantir l'unicité (conformément aux directives spécifiées dans [Mapping SCTE-35 into EXT-X-DATERANGE](https://datatracker.ietf.org/doc/html/draft-pantos-http-live-streaming-23#section-4.3.2.7.1)), MediaTailor associe le `MEDIA-SEQUENCE` numéro du *premier* segment publicitaire de l'annonce au numéro de séquence de l'annonce contenue dans la publication.  
Dans l'exemple suivant, `MEDIA-SEQUENCE` 421 est MediaTailor concatène avec le numéro de position de l'annonce.

# Personnalisation des manifestes DASH avec des métadonnées publicitaires
<a name="ad-id-manifest-dash"></a>

MediaTailor personnalise le manifeste avec les créations renvoyées par le serveur de décision publicitaire (ADS). Pour chaque annonce, inclut MediaTailor également un `EventStream` élément qui couvre la durée de l'annonce. Le format des `Event` éléments est similaire à celui décrit dans la section [Signalisation créative publicitaire dans DASH et HLS](https://www.svta.org/document/draft-ad-creative-signaling-in-dash-and-hls/) de la version 2023 de la publication *technique SVA*.

Pour les pauses publicitaires insuffisamment remplies sur les configurations dans lesquelles Slate MediaTailor est activée, ajoute la période Slate à la fin de la période de disponibilité, mais sans aucune métadonnée `EventStream`

Pour chaque annonce intégrée au manifeste personnalisé, les métadonnées créatives sont MediaTailor ajoutées, représentées sous la forme d'un `CDATA` élément au sein d'un `Event` élément.
