audio or video synchronized with another type of media and/or with time-based interactive components[What is meant by another media type. Does video plus captions count as multimedia? Do you need to refer to primary content? What are animations? Priority AAA]
We have revised the definition as follows:
audio or video synchronized with another format for presenting information and/or with time-based interactive components
By this definition, video plus captions would be considered multimedia. However, since captions are alternatives for speech and sounds, it would be unlikely that a video with captions, but without sound, would be created.
Animations would be multimedia if they were synchronized with another medium such as audio or with time-based interactive components. If the animation contains only video information, then it would not be considered multimedia and would be covered under Guideline 1.1.
