Thanks for the analysis, but two pieces of feedback: 1) Though sub-titles and captions are the most common accessibility issue for audio/video content, they are not the only one. There are people: -- who cannot see, and need audio description of video -- who cannot hear, and prefer sign language -- who have vision issues and prefer high or low contrast video -- who have audio issues and prefer audio that lacks background music, noise, etc. This is only a partial list. Note that some content is only available with open captions (aka burned-in). Clearly sub-optimal, but better than nothing. 2) I think the environment can and should help select and configure type-1 resources, where it can. It shouldn't need to be always a manual step by the user interacting with the media player. That is, I don't see why we cannot have the markup express "this source is better for people who have accessibility need X" (probably as a media query). However, media queries are CSS, not HTML... -- David Singer Multimedia Standards, Apple Inc.
