The HTML 5 working group has been discussing and debating [1] the
accessibility of multimedia features in HTML 5, particularly the new
audio [2] and video [3] elements.

and controlling media assets with some kind of machine-recognizable
mechanism could allow users to choose the format that best suits their
needs. People have different ways of processing information and
allowing multimedia users to shift at will among audio, video,
graphic, and written media may help make these technologies more

and accessibility impact of the new audio [2] and video [3] elements,
as well as your ideas regarding potential solutions would be
