# Decorazione dell'annuncio
<a name="ad-id-decoration"></a>

AWS Elemental MediaTailor esegue l'unione degli annunci sul lato server durante la transizione dai contenuti alle interruzioni pubblicitarie. MediaTailor può condizionare il manifesto con i metadati associati agli annunci che sono stati uniti. In questo modo è possibile ottenere i seguenti vantaggi:

**Importante**  
La decorazione degli ID pubblicitari non è compatibile con i metodi SGAI (Server-Guided Ad Insertion) perché i campi che compongono le `X-AD-CREATIVE-SIGNALING ` intestazioni sono noti solo quando l'elenco delle risorse viene recuperato durante la riproduzione dell'annuncio, non quando il manifesto memorizzabile nella cache viene inizialmente scritto.
+ *L'*ora di avvio del video (VST) migliora
+ MediaTailor può supportare un modello ibrido di inserimento di annunci lato server e inserimento di annunci guidato dal server
+ Le sessioni lato server possono creare linee temporali di riproduzione con indicatori di posizione degli annunci
+ Per le sessioni lato client che già creano timeline di riproduzione con l' MediaTailor API, il VST della sessione migliora, poiché la sessione non si basa sulla chiamata all'API di tracciamento per creare la sequenza temporale
+ È possibile sfruttare l'inserimento di annunci sul lato server e MediaTailor gli annunci renderizzati lato client visualizzati sulla scena. In questo modo, non è necessario che il kit di sviluppo software (SDK) di un giocatore disponga di un'integrazione separata per richiamare direttamente le entità che pubblicano annunci pubblicitari per gli annunci sul lato client. MediaTailor può inviare gli annunci tramite il manifesto e l'API di tracciamento lato client.

Esistono degli standard per associare ogni risorsa pubblicitaria creativa a un identificatore univoco. Questa associazione consente a inserzionisti, agenzie, fornitori ed editori di mettere in relazione una risorsa pubblicitaria creativa nei loro flussi di lavoro indipendenti. Man mano che le metriche e il monitoraggio degli stream continuano a migliorare e sempre più distributori utilizzano architetture di inserimento basate su server, diventa necessario comunicare con precisione gli identificatori assegnati alle singole risorse creative all'interno di una presentazione, ad esempio all'interno del manifesto personalizzato. interleaved/stitched

# Attivazione della segnalazione ad ID per le sessioni
<a name="ad-id-session-state"></a>

La funzionalità di segnalazione degli ID pubblicitari deve essere abilitata durante l'inizializzazione della sessione. Il processo per abilitare la funzionalità è diverso dalla creazione di sessioni utilizzando il prefisso di HLS/DASH riproduzione (inizializzazione implicita della sessione) e il prefisso di inizializzazione della sessione (inizializzazione esplicita della sessione).

**Per abilitare un ID pubblicitario per la sessione utilizzando i prefissi di riproduzione HLS/DASH**
+ Dal lettore, inizializza una nuova sessione di MediaTailor riproduzione utilizzando una richiesta in uno dei seguenti formati, in base al protocollo in uso:
  + Esempio: formato HLS

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

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

**Per abilitare un ID pubblicitario per la sessione utilizzando il prefisso di inizializzazione della sessione**
+ Sul player, crea un corpo del messaggio JSON per la richiesta di inizializzazione della sessione per: MediaTailor 
  + All'interno di un `adsParams` oggetto, fornisci tutti i parametri che MediaTailor devono passare all'ADS. Questi parametri corrispondono alle `[player_params.param]` impostazioni nell'URL del modello ADS della MediaTailor configurazione. 
  + Per abilitare la segnalazione degli ID pubblicitari, aggiungi un `adSignaling` oggetto come oggetto di primo livello e, all'interno, aggiungi un parametro chiamato `enabled` e il valore di`true`. Il `adSignaling` valore predefinito è`disabled`.
  + Esempio: formato HLS

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

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

# Manifesti e inserimento di metadati pubblicitari
<a name="ad-id-manifest"></a>

Durante il processo di creazione degli annunci, MediaTailor aggiunge al manifesto l'ID univoco associato a ciascuna creatività che viene creata. MediaTailor ottiene l'ID univoco della creatività dal valore dell'`id`attributo di tale creatività nella risposta VAST. Se alla creatività manca un valore di attributo ID, MediaTailor pubblicherà un valore vuoto (`id=""`).

MediaTailor utilizza un segnale di metadati in-manifest per disaccoppiare le dipendenze tra l'API di tracciamento dei clienti per i metadati creativi degli annunci e timing/positioning la tempistica generale. Questo disaccoppiamento riduce la latenza di riproduzione (specialmente negli scenari VOD), in cui l'interfaccia utente (UI) del lettore esegue il rendering delle posizioni delle interruzioni pubblicitarie nella timeline prima di inizializzare la riproduzione.

I metadati aggiunti assumono le seguenti forme:
+ Per i manifesti HLS, i metadati aggiunti assumono la forma di `DATERANGE` tag per ogni annuncio nel periodo di disponibilità.
+ Per i manifesti DASH, i metadati aggiunti assumono la forma di un elemento all'interno di ciascun periodo dell'annuncio. `Event`

Il seguente corpo del messaggio JSON mostra un esempio di risposta 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"
    }
  ]
}
```

Nell'esempio precedente:
+ *creativeId*è il valore dell'`Id`attributo dell'`Creative`elemento per l'annuncio
+ *adId*è il numero di sequenza HLS associato all'inizio dell'annuncio o l'ID del periodo DASH dell'annuncio
+ *adType*è `avail` o`overlay`, in base alla risposta VAST
+ *trackingUri*è l'endpoint di tracciamento relativo per la MediaTailor sessione, nel formato `../../../../tracking/hashed-account-id/origin-id/session-id`
+ *customVastData*è un valore che MediaTailor estrae dall'estensione `creative_signaling` VAST. MediaTailor utilizza il contenuto del nodo CDATA, se presente. Vedi la [Interazioni con Ad Decision Server (ADS)](ad-id-ads-interactions.md) sezione per maggiori dettagli e un esempio di risposta VAST.

# Personalizzazione dei manifesti HLS con metadati pubblicitari
<a name="ad-id-manifest-hls"></a>

Per uno streaming HLS live, aggiunge i metadati MediaTailor solo quando lo stream contiene `PROGRAM-DATA-TIME` tag, almeno una volta per durata del manifesto. Per uno stream video on demand (VOD), lo MediaTailor aggiunge `PROGRAM-DATE-TIME` ad almeno un segmento nel manifesto personalizzato, dove l'ora di inizio di ogni risorsa VOD è epoch zero (). `1970-01-01T00:00:00Z` Se il manifesto di origine contiene `PROGRAM-DATE-TIME` contenuti esistenti, li MediaTailor conserva.

MediaTailor personalizza il manifesto con le creatività restituite da Ad Decision Server (ADS). Per ogni annuncio, include MediaTailor anche un `DATERANGE` tag che copre la durata dell'annuncio. *Il formato del `DATERANGE` tag è simile a quello descritto nella sezione [Segnalazione creativa degli annunci in DASH e HLS](https://www.svta.org/document/draft-ad-creative-signaling-in-dash-and-hls/) nella versione 2023 della pubblicazione tecnica SVA.*

`DATERANGE`Quello che MediaTailor genera ha valori ID univoci. Per garantire l'unicità (date le linee guida specificate in [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 associa il `MEDIA-SEQUENCE` numero del *primo* segmento pubblicitario dell'annuncio al numero di sequenza dell'annuncio incluso nella disponibilità.

In caso di interruzioni pubblicitarie insufficienti nelle configurazioni in cui è abilitato Slate, MediaTailor aggiunge i segmenti di slate alla fine dell'elenco, separati da un tag, ma senza metadati. `DISCONTINUITY` `DATERANGE`

Per ogni annuncio inserito nel manifesto personalizzato, MediaTailor aggiunge i metadati creativi, rappresentati come dati codificati in base 64 in un tag personalizzato. `DATERANGE`

**Example Manifesto personalizzato VOD HLS:**  
MediaTailor si aggiunge `PROGRAM-DATE-TIME` ai manifesti VOD per utilizzarli come ancoraggi per gli elementi HLS che indicano le posizioni degli annunci`DATERANGE`.  
`DATERANGE`Quello che MediaTailor genera ha valori ID univoci. Per garantire l'unicità (date le linee guida specificate in [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 associa il `MEDIA-SEQUENCE` numero del *primo* segmento pubblicitario dell'annuncio al numero di sequenza dell'annuncio incluso nella disponibilità.  
Nell'esempio seguente, MediaTailor `MEDIA-SEQUENCE` concatena 421 con il numero di posizione dell'annuncio.

# Personalizzazione dei manifesti DASH con i metadati degli annunci
<a name="ad-id-manifest-dash"></a>

MediaTailor personalizza il manifesto con le creatività restituite da Ad Decision Server (ADS). Per ogni annuncio, include MediaTailor anche un `EventStream` elemento che copre la durata dell'annuncio. *Il formato dell'`Event`elemento è simile a quello descritto nella sezione [Segnalazione creativa degli annunci in DASH e HLS](https://www.svta.org/document/draft-ad-creative-signaling-in-dash-and-hls/) nella versione 2023 della pubblicazione tecnica SVA.*

In caso di interruzioni pubblicitarie insufficienti nelle configurazioni in cui Slate è abilitato, MediaTailor aggiunge il periodo Slate alla fine del periodo di disponibilità, ma senza metadati `EventStream`

Per ogni annuncio inserito nel manifesto personalizzato, MediaTailor aggiunge i metadati creativi, rappresentati come un elemento all'interno di un elemento. `CDATA` `Event`

# Interazioni con Ad Decision Server (ADS)
<a name="ad-id-ads-interactions"></a>

MediaTailor utilizza il valore dell'`id`attributo creativo della risposta VAST come valore nella segnalazione dell'ID dell'annuncio. Se il valore dell'`id`attributo è vuoto o non è presente nella risposta VAST, MediaTailor inserisce un valore vuoto nella segnalazione dell'ID dell'annuncio.

**Example Risposta VAST:**  
Il seguente esempio di risposta VAST include un valore di `id` attributo per il lineare `Creative` in linea. MediaTailor estrae il valore dall'`Extension`elemento VAST personalizzato e lo inserisce nei metadati creativi del manifesto.
