Web Directions South 2009, Sydney Convention Centre, October 8 2.40pm.
This talk focuses on the efforts engaged by W3C to improve the new HTML 5 media elements with mechanisms to allow people to access multimedia content, including audio and video. Such developments are also useful beyond accessibility needs and will lead to a general improvement of the usability of media, making media discoverable and generally a prime citizen on the Web.
Silvia will discuss what is currently technically possible with the HTML5 media elements, and what is still missing. She will describe a general framework of accessibility for HTML5 media elements and present her work for the Mozilla Corporation that includes captions, subtitles, textual audio annotations, timed metadata, and other time-aligned text with the HTML5 media elements. Silvia will also discuss work of the W3C Media Fragments group to further enhance video usability and accessibility by making it possible to directly address temporal offsets in video, as well as spatial areas and tracks.
