So, just what are the basics to know about Multi-Media accessibility?
The Process
Implement W3C WCAG guidelines to fulfill the U.S. Rehabilitation Act.
This Means
Transcripts and captions must be provided and having one does not substitute for having the other.
Captions - must be synchronized, equivalent, and accessible.
Synchronized: The text content appears at the same time as audio.
Equivalent: Captions should be equivalent to that of the spoken word.
Accessible: Captions should be readily accessible and available.
The Presentation
Use multi-media players with accessible controls for stop; pause; previous; and next. The controls must be visible (color and size) and available from the keyboard (not mouse dependent).
