擦洗

為了增強播放體驗，播放器可以在播放時間軸中顯示廣告位置。 MediaTailor 在用戶端追蹤回應中以adStartTimeInSeconds值的形式提供這些廣告位置。

注意

某些串流供應商會防止拖曳超過廣告位置。

以下客戶端跟踪有效負載 JSON 響應顯示 avails 數組的根 JSON 對象內的可用性（廣告插播）開始時間。播放器會使用這項資料，以 28 秒的速度在播放器時間軸上顯示廣告插播的位置。


{

    {
      "adBreakTrackingEvents": [],
      "adMarkerDuration": null,
      "ads": [...],
      "availId": "7",

}

廣告倒數計時器

MediaTailor 您可以使用廣告倒數計時器，協助您在廣告插播期間保持受眾的參與度。觀眾可以使用計時器瞭解廣告插播結束及其計畫恢復的時間。

在廣告倒數計時器中扮演角色的用戶端追蹤中繼資料中的元素為startTimestartTimeInSeondsduration、、和durationInSeconds。播放程式會使用此中繼資料，以及工作階段分別追蹤的經過時間，以決定何時顯示計時器，以及應從中倒數的值。

下列用戶端追蹤承載 JSON 回應會顯示廣告倒數計時器所需的資訊。


{
  "avails": [
    {
      "adBreakTrackingEvents": [],
      "adMarkerDuration": null,
      "ads": [...],
      "availId": "7",
      "availProgramDateTime": null,
      "duration": "PT30S",
      "durationInSeconds": 30,
      "meta": null,
      "nonLinearAdsList": [],
      "startTime": "PT28S",
      "startTimeInSeconds": 28
    }
  ],
  "dashAvailabilityStartTime": null,
  "hlsAnchorMediaSequenceNumber": null,
  "nextToken": "UFQxMk0zNC44NjhTXzIwMjMtMDctMjFUMjA6MjM6MDcuNzc1NzE2MzAyWl8x",
  "nonLinearAvails": []
}

當工作階段的經過時間達到可用程式的開始時間時，玩家會顯示一個倒數計時器，其值與可用性的持續時間相符。倒數計時器值隨著經過時間的進展超出可用性的開始時間而減少。

範例公式：HLS（實時和 VOD）和短跑（VOD）的倒數計時器

session_start_time= 所有EXT-INF持續時間值的總和-三個最新EXT-INF媒體序列的持續時間值
定時器值 = duration-（session_elapsed_time-startTime）

顯示廣告倒數計時器計算的圖表，根據工作階段的開始時間和可用性的開始時間，適用於 HLS (即時和 VOD) 資訊清單。

範例公式：短跑倒數計時器（現場）

session_start_time= (最新區段的 startTime +duration)/timescale-MPD@suggestedPresentationDelay
定時器值 = duration-（session_elapsed_time-startTime）

圖表顯示即時 DASH 資訊清單的廣告倒數計時器計算，根據工作階段的開始時間和可用性的開始時間計算。

可略過的廣告

可略過的廣告是一種廣告點，可讓觀眾略過某些廣告，以繼續觀看該節目。在 VAST 中，Linear@skipOffset屬性可識別可略過的廣告。

以下 VAST 回應說明如何使用可略過廣告：


<?xml version="1.0" encoding="UTF-8"?>
<VAST xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="vast.xsd" version="3.0">

廣告點擊率

點擊率 URI 可讓廣告客戶評估廣告在吸引觀眾注意力方面的成功程度。觀眾按下進行中廣告的作用中影片影格後，網頁瀏覽器就會開啟廣告客戶首頁或廣告活動到達網頁的 URI。播放器開發人員會決定點擊行為，例如覆蓋廣告影片上的按鈕或標籤，並顯示要點擊的訊息以瞭解詳情。播放器開發人員通常會在觀眾點擊作用中的影片影格後暫停廣告的影片。

影片播放器中廣告點閱的螢幕擷取畫面。觀眾按一下視訊影格。播放器會暫停影片，然後開啟網頁瀏覽器，將觀眾帶到廣告系列的首頁或廣告活動登陸頁面。

MediaTailor 可以剖析並提供 VAST 回應中傳回的任何線性視訊點進事件 URL。以下 VAST 回應顯示廣告點閱範例。

配套廣告

隨附廣告會與線性廣告素材一起顯示。使用隨附廣告，透過顯示產品、標誌和品牌資訊來提高廣告位置的有效性。多媒體廣告可以包含快速回應 (QR) 碼和可點選區域，以提升觀眾參與度。

MediaTailor 在 VAST 響應中支持伴隨廣告。它可以分別從StaticResourceiFrameResource、和HTMLResource節點傳遞中繼資料。

以下 VAST 回應顯示線性廣告和隨附廣告的位置和格式範例。

資料會顯示在清單中的用戶端追蹤回應/avail/x/ads/y/companionAds中。每個線性廣告素材最多可包含 6 個隨附廣告。如下列範例所示，隨附廣告會顯示在清單中

注意

最佳做法是，應用程式開發人員應該實作邏輯，以便在廣告素材結束時明確移除或卸載隨附廣告。

互動式廣告

SecureInteractive 媒體介面定義 (SIMID) 是互動式廣告局 (IAB) 在 VAST 4.x 標準中引入的互動式廣告標準。SIMID 會將互動元素的載入與播放器上的主要線性廣告素材分離，並在 VAST 回應中參照這兩者。 MediaTailor 在主要創意中進行縫合以維持播放體驗，並在用戶端追蹤回應中放置互動式元件的中繼資料。

在下列範例 VAST 4 回應中，SIMID 承載位於InteractiveCreativeFile節點內部。

互動式廣告 (付費)

視訊播放器廣告介面定義 (VPAYED) 會指定廣告與視訊播放器之間的通訊協定，以啟用廣告互動和其他功能。對於即時串流，您可以在可用期間拼接平板區段，並將 VPAYED 廣告素材的中繼資料置於視訊播放程式使用的用戶端追蹤回應中，以 MediaTailor 支援 VPAID 格式。播放器下載 VPAYED 文件並播放線性創意並執行客戶端的腳本。玩家應該永遠不會播放板岩片段。

注意

付費被棄用作為浩瀚 4.1.

支付廣告播放圖。 MediaTailor 針對內容時間軸中的可用期間縫合平板區段。在可用期間內，播放器切換到 VPADE 資產。

下面的例子顯示了 VPAYD 內容在巨大的響應。
