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.

The Telecommunications and Electronic Information Technology Advisory Committee was tasked with updating the accessibility standards issued under section 508 of the Rehabilitation Act and guidelines under section 255 of the Telecommunications Act. The committee was formed July 6, 2006 and presented its recommendations to the U.S. Access Board on April 3, 2008.
Additional details on the updates to section 508 and section 255 can be found at the Access Board web site.
