QT PDF AD

This example requires Adobe Acrobat 6. PDF files can include audio described media. As with captioned media in PDF, there is no good way to deliver descriptions so that they can be heard only when desired by the user. Acrobat Reader has a preference that makes it appear that the user can select when to hear descriptions, but this control is of limited use.
