<p>Created</p>
<p><b>New page</b></p><div>The exclusive playlist allows up to one of its children to play. The start of one media object causes the currently playing item to either pause or stop.<br />
<br />
The [[priorityClass]] tag further defines interrupt priorities and behavior (pause, defer, or stop) of media objects when interrupts occur.<br />
<br />
The starting of a media object may be triggered by an event such as a key press or a [[Wallclock]] time, as the following sample code illustrates.<br />
<br />
== Top-of-the-Hour Video ==<br />
<br />
<source lang="smil"><br />
<excl><br />
<br />
<priorityClass><br />
<video begin="wallclock(R/2010-01-01/PT1H)" src="hour.mpg" /><br />
</priorityClass><br />
<br />
<priorityClass higher="pause"><br />
<seq repeatCount="indefinite" begin="0"><br />
<video src="ad1.mpg" /><br />
<video src="ad2.mpg" /><br />
<video src="ad3.mpg" /><br />
</seq><br />
</priorityClass><br />
<br />
</excl><br />
</source><br />
<br />
This exclusive playlist contains two priority classes.<br />
<br />
The first (higher) priority class contains a single video "hour.mpg" that begins on the top of each hour, starting on midnight of January 1, 2010. See [[Wallclock]] for detailed ISO-8601 specification.<br />
<br />
The second (lower) priority class contains a sequential playlist, that begins at "zero" seconds (immediately as the <excl> playlist is entered). While the sequence plays, when a higher priority class is triggered, the then playing item is "paused" as the interrupting media object plays. After it finishes, the paused media object resumes.<br />
<br />
This achieves the effect of looping three videos, and interrupting with another on the top of every hour.<br />
