This talk focuses on the efforts engaged by W3C and its members to promote and improve web standards and in particular HTML 5 with mechanisms to allow people with disabilities to access multimedia content, including audio and video. Scott will present the current user experiences of accessibility and the challenges of getting uptake in government. This would include the take-up of W3C access standards within government, use of WCAG and ATAG by developers, the technical challenges of video-specific implementations of captioning and audio description, and ways in which such challenges can be better addressed through the involvement of Internet users.
