Accessibilistas:

I understand accessibility for video tapes, DVD's, and video on the
Web: provide Closed Captioning in vertical blanking line 21 (NTSC at
least) of the mechanical media (for want of a better term) and
provide Closed Captioning in a SMIL layer for video on the Web.

I can extrapolate to vodcasting as long as it's watched on the Web:
provide Closed Captioning in a SMIL layer.

My question is: how about when it's being watched on a video iPod or
similar device? Provide Open Captions in that case? How to
differentiate the files - watched on the Web w/SMIL vs. watched on
iPod w/Open Captions? I don't have a video iPod or I'd try this
myself: does the SMIL layer appear with the vodcast on the video
iPod? I can't imagine that it does. How would the user turn it on/off?

Enquiring minds want to know:-)

PS: Audio description of video is a further refinement--

(I love the fact that a Dr. Who box set is available not only with
audio description of video, but also talking menus:-)
