Re: Clarification of SC 1.2.3

Thanks, Jonathan, that makes sense. Synchronization would be meaningful in most cases (perhaps not as important for someone who is both deaf and blind, but certainly for others).

Subject: Clarification of SC 1.2.3    Hi Everyone--    We were discussing SC 1.2.3 (Audio Description or Media Alternative) and were puzzled by the A and AA requirements. I wonder if anyone has had a similar reaction.    In terms of accessibility, wouldn't it be better to require a transcript than an audio description? As I understand it, a transcript would provide a more complete rendering of a video since it would include both audio and visual content, whereas an audio description only includes visual content not contained in the audio track. A transcript would also be more accessible to persons using a Braille reader.    Was the decision to make audio descriptions a Level AA requirement based on how few players could provide them, i.e., the assumption that providing a transcript was easier, therefore more reasonable to meet Level A? Or was a synchronized presentation using audio descriptions considered to be more comparable to a sighted experience than an asynchronous transcript?    It seems to me that a transcript would be preferable to audio descriptions, therefore optional for Level A but required for Level AA, but perhaps I'm missing something.    Thanks!    Mike
