Captioning both live and recorded video is a requirement under the Web Content Accessibility Guidelines (WCAG) 2.0, Level AA. Providing audio description for pre-recorded video is also required. The WCAG requirements are included in Section 508 of the United States Rehabilitation Act and also in several state web accessibility laws. Oklahoma is one of those states.
