+# How to: Repeat Media Playback
+This example shows how to playback media indefinitely, that is, to set media so that it plays in an infinite loop.  
+  
+## Example  
+ The following example uses <xref:System.Windows.Controls.MediaElement> and <xref:System.Windows.Media.MediaTimeline> in a <xref:System.Windows.Media.Animation.Storyboard> to play a media clip in an infinite loop.
