Remarks

This property is read-only when applied to the playitem object.

html+time (timed interactive multimedia extensions) 2.0 supports media that includes captioning stream technology, called synchronized accessible media interchange (sami). the src attribute of a media element can use the #sami suffix to include captioning with media playback. for more information, see adding closed captions to digital media and Understanding SAMI 1.0.

Security Alert  When the #sami suffix is specified with a valid URL for the SRC attribute of a media element, the contents of the SAMI stream display as text in that element. Likewise, the stream contents can be returned as the innertext of that element. for security reasons, developers should regard the sami stream as user input and take routine precautions against displaying unconfirmed user input as html rather than text. for more information, see security considerations: dynamic html and security considerations: dhtml and default behaviors.
