# Decoração de ID do anúncio
<a name="ad-id-decoration"></a>

AWS Elemental MediaTailor realiza a junção de anúncios do lado do servidor ao fazer a transição do conteúdo para os intervalos publicitários. MediaTailor pode condicionar o manifesto com metadados associados aos anúncios que foram criados. Fazer isso pode oferecer os seguintes benefícios:

**Importante**  
A decoração do Ad-ID não é compatível com os métodos de inserção de anúncios guiada pelo servidor (SGAI) porque os campos que preenchem os `X-AD-CREATIVE-SIGNALING ` cabeçalhos só são conhecidos quando a lista de ativos é buscada durante a reprodução do anúncio, não quando o manifesto que pode ser armazenado em cache é gravado inicialmente.
+ O *horário de início do vídeo* (VST) melhora
+ MediaTailor pode suportar um modelo híbrido de inserção de anúncios do lado do servidor e inserção de anúncios guiada pelo servidor
+ As sessões do lado do servidor podem criar cronogramas de reprodução com marcadores de posição do anúncio
+ Para sessões do lado do cliente que já criam cronogramas de reprodução com a MediaTailor API, o VST da sessão melhora, pois a sessão não depende da chamada da API de rastreamento para criar a linha do tempo
+ É possível aproveitar a inserção MediaTailor de anúncios do lado do servidor, bem como os anúncios renderizados do lado do cliente exibidos na cena. Dessa forma, o kit de desenvolvimento de software (SDK) de um player não precisa ter uma integração separada para chamar entidades de veiculação de anúncios diretamente para anúncios do lado do cliente. MediaTailor pode vender os anúncios por meio do manifesto e da API de rastreamento do lado do cliente.

Existem padrões para associar cada recurso de anúncio criativo a um identificador exclusivo. Essa associação permite que anunciantes, agências, fornecedores e editores relacionem um ativo publicitário criativo em seus fluxos de trabalho independentes. À medida que as métricas e o monitoramento dos fluxos continuam melhorando e mais distribuidores utilizam arquiteturas de inserção baseadas em servidor, surge a necessidade de comunicar com precisão os identificadores atribuídos aos ativos criativos individuais em uma interleaved/stitched apresentação, como no manifesto personalizado.

# Habilitando a sinalização de ID de anúncio para sessões
<a name="ad-id-session-state"></a>

O recurso de sinalização de ID de anúncio deve ser ativado durante a inicialização da sessão. O processo para ativar o recurso é diferente de criar sessões usando o prefixo de HLS/DASH reprodução (inicialização implícita da sessão) versus o prefixo de inicialização da sessão (inicialização explícita da sessão).

**Para ativar o ID de anúncio para a sessão usando prefixos de HLS/DASH reprodução**
+ No player, inicialize uma nova sessão de MediaTailor reprodução usando uma solicitação em um dos seguintes formatos, de acordo com seu protocolo:
  + Exemplo: formato HLS

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

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

**Para habilitar o ID de anúncio para a sessão usando o prefixo de inicialização da sessão**
+ No player, construa um corpo de mensagem JSON para a solicitação de inicialização da sessão para: MediaTailor 
  + Dentro de um `adsParams` objeto, forneça todos os parâmetros que MediaTailor devem ser passados para o ADS. Esses parâmetros correspondem às `[player_params.param]` configurações na URL do modelo ADS da MediaTailor configuração. 
  + Para ativar a sinalização de ID de anúncio, adicione um `adSignaling` objeto como objeto de nível superior e, dentro, adicione um parâmetro chamado `enabled` e valor de. `true` O `adSignaling` valor padrão é`disabled`.
  + Exemplo: formato HLS

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

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

# 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`

# Interações do Ad Decision Server (ADS)

MediaTailor usa o valor do `id` atributo criativo da resposta VAST como um valor na sinalização do ID do anúncio. Se o valor do `id` atributo estiver vazio ou não estiver presente na resposta VAST, MediaTailor insere um valor vazio na sinalização do ID do anúncio.

**Example Resposta VAST:**  
O exemplo de resposta VAST a seguir inclui um valor de `id` atributo para o linear `Creative` em linha. MediaTailor extrai o valor do `Extension` elemento VAST personalizado e coloca esse valor nos metadados criativos do manifesto.
