At least for now, I'm talking about the first case. A good example movie with
extended descriptions (provided by WGBH) is found at
http://web.mac.com/eric.carlson/w3c/NCAM/extended-audio.html . The background
of this technology is introduced at
http://www.w3.org/WAI/PF/HTML/wiki/Media_Accessibility_Requirements#Extended_video_descriptions
.

SMIL is known as means to provide this type of descriptions (
http://www.w3.org/TR/WCAG-TECHS/SM1 and http://www.w3.org/TR/WCAG-TECHS/SM2 ),
but SMIL seems to be too much for this purpose. So we are testing a simpler way
to present extended descriptions (using an "extended" flag) in our prototype
auditory browser ( http://www.eclipse.org/actf/downloads/tools/aiBrowser/ ).

My original intention to post this bug was that APIs like
media.pauseInternally() will allow to provide extended descriptions using
JavaScript even if they are not natively supported by browsers. However, of
course it will be better if extended descriptions are natively supported.
