I set up the thought experiment; it's one of those annoying web sites that wants to tell you everything in videos, ok? > That's what the video is about. That's right. And that's what the accessibility-needing user wants to learn about. Not the artistic design of one frame of the video. > You have to play the video to learn.

It is vanishingly unimportant to describe one frame of a video, while simultaneously failing to describe the video itself. If we had brilliant designs that were complete and covering the obvious needs -- needs that we talked about years ago in the Stanford meeting -- I wouldn't mind if we were tidying up loose ends. But in all this focus on longdesc, and posters, we have done almost nothing for video transcripts, repetitive stimulus avoidance, color blindness or a whole host of other real problems. Even the captioning isn't striving to do any better than basic television. David Singer Multimedia and Software Standards, Apple Inc.
