Some requirements links & questions

Since we don't have a compiled set of requirements yet, I gathered 
the different requirements links related to accessible media that I'm 
aware of, and some questions. Please add to the list of links of 
requirement sets if there are others, and/or to the list of questions 
-- thanks.

http://www.w3.org/WAI/PF/HTML/wiki/Multimedia_Q%26A
- this page has only about 8 lines of basic need statements, then the 
rest is info about other things for instance accommodation types, 
provision, detection, formats

https://wiki.mozilla.org/Accessibility/Video_a11y_requirements
- after some narrative thoughts about requirements, from mid-page & 
on there's a list w/ linked details on some disability-related 
functional needs, as well as requirements for internationalization, 
entertainment, archiving etc

http://wiki.whatwg.org/wiki/Timed_tracks
- requirements specifically for timed-track features in HTML

http://www.w3.org/html/wg/wiki/MultimediaAccessibility
- nothing there


A few starter questions regarding requirements (borrowing from 
various contexts, including some recent contributions)

- Most of these requirements documents seem to consider that someone 
might have difficulty seeing, or hearing, but not both. (Disabilities 
don't always get handed out one at a time.) Can someone help capture 
requirements for deaf-blind users -- a term which at least in some 
countries encompasses users any combination of some to full vision 
impairment and some to full hearing impairment, in other words a wide 
range of user requirements? This has implications for instance on the 
requirements for the presentation of captions.

- Any captures of accessibility requirements for people with 
cognitive disabilities, for instance who might need to see and hear 
text at the same time?

- Requirements for preserving and carrying through captions and audio 
description from one format to another?

- What about requirements for controls of captions & audio 
description (start, stop, fast fwd, rewind, etc)

- What about requirements for structured nav of longer chunks of video?

- Other questions regarding aspects not already captured requirements 
documentation (apart from features of any particular approach)?

Thanks,

- Judy
