已略過章節的 VOD 播放 vod-playback-with-a-skipped-chapter
情境 scenario
此情境中，使用者會在主要內容中略過某個章節。
這是與單一章節 VOD 播放相同的情境，只是此情境中的使用者要超出章節範圍搜尋，因此略過該章節，直接進入主要內容。
觸發
心率方法
網路呼叫
附註
使用者點按 「播放」
trackSessionStartAnalytics 內容開始、心率內容開始
Measurement Library 不知道有前段廣告。這些網路呼叫仍完全等同於iOS🔗案例中沒有岔斷的播放。
章節開始。
trackEvent:ChapterStart心率章節開始
播放章節的第一個時間格。
trackPlay心率章節播放
當章節內容在主要內容之前播放，我們想在章節開始時啟動心率。
章節播放。
章節心率
搜尋會開始略過第一個章節。
trackEvent:trackSeekStart搜尋期間沒有心率
搜尋已完成。
trackEvent:trackSeekComplete心率會在此之後繼續。
應用程式發現使用者的搜尋已超出正常章節範圍。
trackEvent:trackChapterSkip內容播放。
內容心率
工作階段已結束。
trackSessionEndSessionEnd 表示檢視工作階段的結尾。即使使用者未持續觀看到媒體完成，仍必須呼叫此 API。參數 parameters
除了沒有章節完成網路呼叫以外，章節播放期間使用的參數完全等同於 具有一個章節的 VOD 播放 情境中的參數。
