# Manifestos e inserção de metadados de anúncios
<a name="ad-id-manifest"></a>

Durante o processo de criação do anúncio, MediaTailor adiciona ao manifesto o ID exclusivo associado a cada criação que está sendo costurada. MediaTailor obtém a ID exclusiva do criativo a partir do valor do `id` atributo desse criativo na resposta VAST. Se o criativo não tiver um valor de atributo de ID, MediaTailor publicará um valor vazio (`id=""`).

MediaTailor usa um sinal de metadados no manifesto para separar as dependências entre a API de rastreamento do cliente para metadados criativos de anúncios e dentro do cronograma geral. timing/positioning Esse desacoplamento reduz a latência da reprodução (especialmente em cenários de VOD), em que a interface do usuário (UI) do player renderiza as posições de interrupção do anúncio na linha do tempo antes de inicializar a reprodução.

Os metadados adicionados assumem as seguintes formas:
+ Para manifestos HLS, os metadados adicionados assumem a forma de `DATERANGE` tags para cada anúncio no período de disponibilidade.
+ Para manifestos do DASH, os metadados adicionados assumem a forma de um `Event` elemento dentro de cada período do anúncio.

O corpo da mensagem JSON a seguir mostra um exemplo de resposta 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"
    }
  ]
}
```

No exemplo anterior:
+ *creativeId*é o valor do `Id` atributo do `Creative` elemento para o anúncio
+ *adId*é o número de sequência HLS associado ao início do anúncio ou o ID do período DASH do anúncio
+ *adType*é `avail` ou`overlay`, com base na resposta VAST
+ *trackingUri*é o endpoint de rastreamento relativo da MediaTailor sessão, no formato `../../../../tracking/hashed-account-id/origin-id/session-id`
+ *customVastData*é um valor MediaTailor extraído da extensão `creative_signaling` VAST. MediaTailor usa o conteúdo do nó CDATA, se presente. Consulte a [Interações do Ad Decision Server (ADS)](ad-id-ads-interactions.md) seção para obter mais detalhes e um exemplo de resposta VAST.

# Personalização de manifestos HLS com metadados de anúncios
<a name="ad-id-manifest-hls"></a>

Para um stream HLS ao vivo, MediaTailor só adiciona metadados quando o stream contém `PROGRAM-DATA-TIME` tags, pelo menos uma vez por duração do manifesto. Para um stream de vídeo sob demanda (VOD), é MediaTailor adicionado `PROGRAM-DATE-TIME` a pelo menos um segmento no manifesto personalizado, em que a hora de início de cada ativo de VOD é a época zero (). `1970-01-01T00:00:00Z` Se o manifesto de origem tiver `PROGRAM-DATE-TIME` conteúdo existente, MediaTailor preservará esse conteúdo.

MediaTailor personaliza o manifesto com criativos retornados pelo Ad Decision Server (ADS). Para cada anúncio, MediaTailor também inclui uma `DATERANGE` tag que abrange a duração do anúncio. *O formato da `DATERANGE` tag é semelhante ao descrito na seção [Sinalização criativa de anúncios em DASH e HLS](https://www.svta.org/document/draft-ad-creative-signaling-in-dash-and-hls/) na versão 2023 da publicação técnica do SVA.*

O `DATERANGE` que MediaTailor gera tem valores de ID exclusivos. Para garantir a exclusividade (de acordo com as diretrizes especificadas em [Mapeamento do SCTE-35 em EXT-X-DATERANGE](https://datatracker.ietf.org/doc/html/draft-pantos-http-live-streaming-23#section-4.3.2.7.1)) MediaTailor , associa o `MEDIA-SEQUENCE` número do *primeiro* segmento do anúncio do item ao número de sequência do anúncio dentro do item.

Para intervalos publicitários não preenchidos em configurações que têm o slate ativado, MediaTailor anexa os segmentos do slate ao final da disponibilidade, separados por uma `DISCONTINUITY` tag, mas sem metadados. `DATERANGE`

Para cada anúncio incluído no manifesto personalizado, MediaTailor adiciona os metadados criativos, representados como dados codificados em base64 em uma tag personalizada. `DATERANGE`

**Example Manifesto personalizado VOD HLS:**  
MediaTailor adiciona `PROGRAM-DATE-TIME` aos manifestos de VOD para usá-los como âncoras para os `DATERANGE` elementos HLS que indicam as posições do anúncio.  
O `DATERANGE` que MediaTailor gera tem valores de ID exclusivos. Para garantir a exclusividade (de acordo com as diretrizes especificadas em [Mapeamento do SCTE-35 em EXT-X-DATERANGE](https://datatracker.ietf.org/doc/html/draft-pantos-http-live-streaming-23#section-4.3.2.7.1)) MediaTailor , associa o `MEDIA-SEQUENCE` número do *primeiro* segmento do anúncio do item ao número de sequência do anúncio dentro do item.  
No exemplo a seguir, MediaTailor concatena `MEDIA-SEQUENCE` 421 com o número da posição do anúncio.

# Personalização de manifestos do DASH com metadados de anúncios
<a name="ad-id-manifest-dash"></a>

MediaTailor personaliza o manifesto com criativos retornados pelo Ad Decision Server (ADS). Para cada anúncio, MediaTailor também inclui um `EventStream` elemento que abrange a duração do anúncio. *O formato do `Event` elemento é semelhante ao descrito na seção [Sinalização criativa de anúncios em DASH e HLS](https://www.svta.org/document/draft-ad-creative-signaling-in-dash-and-hls/) na versão 2023 da publicação técnica do SVA.*

Para intervalos publicitários não preenchidos em configurações que têm o Slate ativado, MediaTailor acrescenta o período do Slate ao final do período de disponibilidade, mas sem nenhum metadado `EventStream`

Para cada anúncio incluído no manifesto personalizado, MediaTailor adiciona os metadados criativos, representados como um `CDATA` elemento dentro de um elemento. `Event`
