SMPTE Timed Text

The U.S Federal Communications Commission (FCC) has declared the closed-captioning standard for online video content developed by the Society of Motion Picture and Television Engineers (SMPTE) – the worldwide leader in motion-imaging standards and education for the communications, media, and entertainment industries – to be a safe harbor interchange and delivery format. The ruling means that captioned video content distributed via the Internet that uses the SMPTE standard – known officially as SMPTE Timed Text – will comply with the 21st Century Communications and Video Accessibility Act (CVAA), a landmark U.S. law designed to ensure the accessibility, usability, and affordability of broadband, wireless, and Internet technologies for people with disabilities.

The standard and all its parts are available at no charge.
