What standards exist for developing and purchasing accessible video and multimedia products?

The U.S. Architectural and Transportation Barriers Compliance Board (Access Board), as mandated by the 1998 Section 508 amendment to the Rehabilitation Act of 1973, developed standards for electronic and information technology developed, maintained, procured, or used by the federal government and covered state entities. These standards became effective in 2001. Some organizations not required to comply with 508 have adopted and used these standards voluntarily. For more information on the standards for video and multimedia products, you can read the Access Board's article Video and Multimedia Products.
