具有连续跟踪的实时主内容

方案

在此方案中，有一个实时资产，在加入实时流后 40 秒内不播放任何广告。

此方案与不含广告的 VOD 播放方案相同，但是部分内容会被清除，并且会从主内容的一个点到另一个点完成搜寻。

参数

心率内容开始

心率内容播放

这应该与心率内容开始调用的外观完全相同，但与“s:event:type”参数的关键区别在于。 所有参数仍应位于此处。

内容心率

在媒体播放期间，有一个计时器将会每 10 秒发送一次主内容的一个或多个心率，每 1 秒发送一次广告的一个或多个心率。这些心率将包含有关播放、广告、缓冲和许多其他内容的信息。每个心率的确切内容不在本文档涵盖的范围之内，验证的关键内容是在持续播放期间始终触发心率。

在内容心率中，查找一些特定的内容：

心率内容结束

当任何给定剧集的播放结束时（播放头跨越剧集边界），将发送“心率内容结束”调用。此调用看起来类似于其他心率调用，但包含几个特定的参数：
