用戶端廣告追蹤的播放器控制項和功能

MediaTailor 用戶端追蹤中繼資料支援各種播放器控制項和功能。下列清單說明熱門播放器控制項。

刷洗

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 會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刷洗超過廣告位置。

螢幕擷取畫面顯示廣告播放的影片時間軸中的 MediaTailor 標記位置。

下列用戶端追蹤承載JSON回應顯示可用陣列根JSON物件內的可用 （廣告中斷） 開始時間。播放器使用此資料在 28 秒時，在播放器時間軸上顯示廣告中斷的位置。

    }
  ],

廣告倒數計時器

使用 MediaTailor ，您可以使用廣告倒數計時器，協助觀眾在廣告中斷檢視期間保持參與。觀眾可以使用計時器來了解廣告休息時間結束及其程式繼續的時間。

MediaTailor 顯示廣告倒數計時器的螢幕擷取畫面，告訴觀眾其程式繼續之前剩餘的時間。

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 startTime、startTimeInSeonds、 duration和 durationInSeconds。播放器會使用此中繼資料，以及其個別追蹤的工作階段經過時間，來決定何時顯示計時器，以及應該從中倒數的值。

下列用戶端追蹤承載JSON回應會顯示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開始時間時，播放器會顯示一個倒數計時器，其中包含符合可用持續時間的值。倒數計時器值會隨著經過的時間進展超過可用開始時間而減少。

範例 公式： HLS（即時 和 VOD） 和 DASH（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

  • 計時器值 = 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開始時間，針對 HLS（即時 和 VOD） 和 DASH（VOD） 資訊清單。
範例 公式： 的倒數計時器 DASH（即時）

  • session_start_time = （最新客群的 startTime + duration） / timescale - MPD@suggestedPresentationDelay

  • 計時器值 = duration - （session_elapsed_time - startTime）

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

可略過的廣告

可略過的廣告是廣告點，可讓檢視器略過某些廣告以繼續檢視程式。在 中VAST， Linear@skipOffset 屬性會識別可略過的廣告。

下列VAST回應顯示如何使用可略過的廣告：

廣告點擊次數

點閱URIs可讓廣告商測量廣告在吸引觀眾注意方面的成功程度。檢視器按一下進行中廣告的作用中影片影格後，網頁瀏覽器會開啟廣告商首頁或行銷活動登陸頁面URI的 。播放器開發人員會決定點擊行為，例如在廣告影片上覆蓋按鈕或標籤，並顯示要按一下 以進一步了解的訊息。玩家開發人員通常會在觀眾按一下作用中影片影格後暫停廣告的影片。

影片播放器中廣告點擊次數的螢幕擷取畫面。觀眾按一下影片影格。播放器會暫停影片，然後開啟 Web 瀏覽器，將檢視器導向廣告商的首頁或行銷活動登陸頁面。

MediaTailor 可以剖析和提供VAST回應中URLs傳回的任何線性影片點擊事件。下列VAST回應顯示廣告點擊率範例。

相配廣告

搭配廣告會顯示在線性創意旁。使用搭配廣告，透過顯示產品、標誌和品牌資訊來提高廣告點的有效性。顯示廣告可以具有快速回應 （QR） 代碼和可點擊區域，以促進受眾參與。

MediaTailor 支援VAST回應中的搭配廣告。它可以分別從 StaticResource、 iFrameResource和 HTMLResource節點傳遞中繼資料。

下列VAST回應顯示線性廣告和相配廣告的範例位置和格式。

資料會顯示在/avail/x/ads/y/companionAds清單中的用戶端追蹤回應中。每個線性創意最多可以包含 6 個搭配廣告。如以下範例所示，搭配廣告會顯示在清單中

注意

最佳實務是，應用程式開發人員應實作邏輯，在創意結束時明確移除或卸載搭配廣告。

互動式廣告 （SIMID）

SecureInteractive 媒體界面定義 （SIMID） 是互動式廣告的標準，該標準是在互動式廣告局 （） 的 VAST 4.x 標準中引入IAB。SIMID 從播放器的主要線性創意解耦互動式元素的載入，在VAST回應中參考兩者。在主要創意中 MediaTailor 接合以維持播放體驗，並將互動式元件的中繼資料放置在用戶端追蹤回應中。

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

互動式廣告 （VPAID）

Video Player Ad Interface Definition （VPAID） 指定廣告與影片播放器之間的通訊協定，以啟用廣告互動性和其他功能。對於即時串流， MediaTailor 支援VPAID格式的方式是，在可用期間在 中接合 Slate 區段，並在影片播放器使用的用戶端追蹤回應中放置VPAID創意者的中繼資料。播放器會下載VPAID檔案並播放線性創意，並執行用戶端的指令碼。播放器不應播放板塊區段。

注意

VPAID 自 VAST 4.1 起已棄用。

VPAID 廣告播放的圖表。 會在內容時間軸中 MediaTailor 接合可用持續時間的 Slate 區段。播放器會在可用持續時間內切換至VPAID資產。

下列範例顯示VAST回應中的VPAID內容。
