These include captions, subtitles, descriptions, and chapters (as in: navigation), as well as multitrack audio and video support (for audio descriptions and sign language). Also, there was a media group in the accessibility task force of HTML5 which specified a requirements list, see http://www.w3.org/WAI/PF/HTML/wiki/Media_Accessibility_Requirements . Is there any requirement you have that is not yet considered? Regards, Silvia.
