# Inserción de manifiestos y metadatos de anuncios
<a name="ad-id-manifest"></a>

Durante el proceso de unión de anuncios, MediaTailor añade al manifiesto el identificador único asociado a cada creatividad que se esté uniendo. MediaTailor obtiene el identificador único de la creatividad a partir del valor de `id` atributo de esa creatividad en la respuesta de VAST. Si la creatividad carece de un valor de atributo de identificación, MediaTailor publicará un valor vacío (`id=""`).

MediaTailor utiliza una señal de metadatos en el manifiesto para desvincular las dependencias entre la API de seguimiento de clientes para los metadatos de las creatividades publicitarias y timing/positioning dentro del cronograma general. Esta disociación reduce la latencia de reproducción (especialmente en situaciones de vídeo a la carta), ya que la interfaz de usuario (UI) del reproductor representa las posiciones de los cortes de anuncios en la línea temporal antes de inicializar la reproducción.

Los metadatos añadidos adoptan las siguientes formas:
+ En el caso de los manifiestos HLS, los metadatos añadidos adoptan la forma de `DATERANGE` etiquetas para cada anuncio durante el período de validez.
+ En el caso de los manifiestos de DASH, los metadatos añadidos adoptan la forma de un `Event` elemento dentro de cada período publicitario.

El siguiente cuerpo del mensaje en JSON muestra un ejemplo de la respuesta 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"
    }
  ]
}
```

En el ejemplo anterior:
+ *creativeId*es el valor del `Id` atributo del `Creative` elemento del anuncio
+ *adId*es el número de secuencia HLS asociado al principio del anuncio o el identificador del período DASH del anuncio
+ *adType*es `avail` o `overlay` se basa en la respuesta de VAST
+ *trackingUri*es el punto final de seguimiento relativo de la MediaTailor sesión, en el formato `../../../../tracking/hashed-account-id/origin-id/session-id`
+ *customVastData*es un valor que se MediaTailor extrae de la extensión `creative_signaling` VAST. MediaTailor utiliza el contenido del nodo CDATA, si está presente. Consulte la [Interacciones con el servidor de decisiones publicitarias (ADS)](ad-id-ads-interactions.md) sección para obtener más detalles y un ejemplo de la respuesta VAST.

# Personalización de los manifiestos HLS con metadatos de anuncios
<a name="ad-id-manifest-hls"></a>

En el caso de una transmisión HLS en directo, MediaTailor solo se añaden metadatos cuando la transmisión contiene `PROGRAM-DATA-TIME` etiquetas, al menos una vez por duración del manifiesto. En el caso de una transmisión de vídeo bajo demanda (VOD), MediaTailor añade `PROGRAM-DATE-TIME` al menos un segmento del manifiesto personalizado, en el que la hora de inicio de cada recurso de VOD sea cero (). `1970-01-01T00:00:00Z` Si el manifiesto de origen tiene `PROGRAM-DATE-TIME` contenido existente, MediaTailor conserva ese contenido.

MediaTailor personaliza el manifiesto con las creatividades devueltas por el Ad Decision Server (ADS). Para cada anuncio, MediaTailor también incluye una `DATERANGE` etiqueta que abarca toda la duración del anuncio. El formato de las `DATERANGE` etiquetas es similar al descrito en la sección [Señalización creativa de anuncios en DASH y HLS](https://www.svta.org/document/draft-ad-creative-signaling-in-dash-and-hls/) de la versión 2023 de la publicación técnica de la *SVA*.

El `DATERANGE` que se MediaTailor genera tiene valores de identificación únicos. Para garantizar la exclusividad (según las directrices especificadas en la [asignación del SCTE-35 a EXT-X-DATERANGE](https://datatracker.ietf.org/doc/html/draft-pantos-http-live-streaming-23#section-4.3.2.7.1)) MediaTailor , combina el `MEDIA-SEQUENCE` número del *primer* segmento de anuncio de la oferta con el número de secuencia del anuncio incluido en ella.

En el caso de las pausas publicitarias poco pobladas en las configuraciones que tienen habilitada la opción tablilla, MediaTailor añade los segmentos de la lista al final de la tirada, separados por una etiqueta, pero sin metadatos. `DISCONTINUITY` `DATERANGE`

Para cada anuncio incluido en el manifiesto personalizado, MediaTailor añade los metadatos creativos, representados como datos codificados en base64 en una etiqueta personalizada. `DATERANGE`

**Example Manifiesto HLS lineal personalizado (con señalización publicitaria creativa):**  
El `DATERANGE` que se MediaTailor genera tiene valores de identificación únicos. Para garantizar la exclusividad (según las directrices especificadas en la [asignación del SCTE-35 a EXT-X-DATERANGE](https://datatracker.ietf.org/doc/html/draft-pantos-http-live-streaming-23#section-4.3.2.7.1)) MediaTailor , combina el `MEDIA-SEQUENCE` número del *primer* segmento de anuncio de la oferta con el número de secuencia del anuncio incluido en ella.  
En el siguiente ejemplo, MediaTailor concatena `MEDIA-SEQUENCE` 421 con el número de posición del anuncio.

**Example Manifiesto personalizado VOD HLS:**  
MediaTailor se añade `PROGRAM-DATE-TIME` a los manifiestos de VOD para utilizarlos como anclajes para los `DATERANGE` elementos HLS que indican las posiciones de los anuncios.  
El `DATERANGE` que se MediaTailor genera tiene valores de ID únicos. Para garantizar la exclusividad (según las directrices especificadas en la [asignación del SCTE-35 a EXT-X-DATERANGE](https://datatracker.ietf.org/doc/html/draft-pantos-http-live-streaming-23#section-4.3.2.7.1)) MediaTailor , combina el `MEDIA-SEQUENCE` número del *primer* segmento de anuncio de la oferta con el número de secuencia del anuncio incluido en ella.  
En el siguiente ejemplo, MediaTailor concatena `MEDIA-SEQUENCE` 421 con el número de posición del anuncio.

# Personalización de los manifiestos de DASH con metadatos de anuncios
<a name="ad-id-manifest-dash"></a>

MediaTailor personaliza el manifiesto con las creatividades devueltas por el Ad Decision Server (ADS). Para cada anuncio, MediaTailor también incluye un `EventStream` elemento que abarca toda la duración del anuncio. El formato de los `Event` elementos es similar al descrito en la sección [Señalización creativa de anuncios en DASH y HLS](https://www.svta.org/document/draft-ad-creative-signaling-in-dash-and-hls/) en la versión 2023 de la publicación técnica de la *SVA*.

En el caso de pausas publicitarias insuficientemente pobladas en configuraciones en las que se haya activado la lista, MediaTailor añade el período de espera al final del período de disponibilidad, pero sin metadatos `EventStream`

Para cada anuncio incluido en el manifiesto personalizado, MediaTailor añade los metadatos de la creatividad, representados como un `CDATA` elemento dentro de otro elemento. `Event`
