PDF QT CC

This example requires Adobe Acrobat 6. PDF files can include captioned media. Unfortunately, there is no good way to deliver captions so that they can be viewed only when desired by the user. Acrobat Reader has a preference that makes it appear that the user can select when to view captions, but this control is of limited use.
