Question about WCAG 1.2.1

[Maria Moore]

Hi, I am a bit unclear about the note on http://www.w3.org/TR/UNDERSTANDING-WCAG20/media-equiv-av-only-alt.html, that says Note: A text equivalent is not required for audio that is provided as an equivalent for video with no audio information. For example, it is not required to caption video description that is provided as an alternative to a silent movie.   Surely this does not assist deaf-blind people? I would have thought that a text equivalent would be needed.   Regards Maria Maria Moore Senior Project Officer, University Web & Learning Services Information Technology Resources Email: maria.mo...@utas.edu.au | Tel: +61 3 6226 6387 | Mob: +61 438 301 002 | Fax: +61 3 6226 7171 Web: www.utas.edu.au Mail: University of Tasmania, Private Bag 69, Hobart  TAS   7001 P  Please consider the environment before printing this email
