David, Its fine if people want to create extended audio descriptions...but they have absolutely no obligation to do that under our guidelines. that's not exactly true, if someone wants to address 1.2.5 to reach level 3 they might need to. But if they want to do that, it is fine to introduce code to jump *over* audio descriptions. However, I don't think users who want to use descriptions should be required jump *to* the descriptions and then back again to the captions hundreds of times just to read the descriptions. That would be like reading a novel while turning on and off the light - a degraded experience. I've proposed this idea based on conversations I've had with a blind user of audio description. I don't think that it should always be used, but it has its place, and not always as an enhanced version. The likelihod that we'll see multiple versions of audio descriptions approaches zero. I'd like the guideline to read something like: 1.1.6 For prerecorded multimedia content, a combined document presenting captions and audio description transcription information in a manner that allows users to access the information in linear order. I probably don't have the words right, but I don't think that when the best information we have is either anecdotal or "mesearch" that the WCAG should be precluding viable techniques. It's hard for me to imagine an organization that would create extended descriptions to help blind people and then require them to go through the experience of jumping back and forth every couple of sentences just to get to them. To me that is counter intuitive. We need better data from users before declaring that counter intutive is incorrect. If they want to create extended descriptions, great, put a "skip over" link for those who don't want to read them. Our current wording completely allows that. But I don't think we should make people who do want to use descriptions suffer by adding all kinds of unnecessary keystrokes just to get to the information. I'm not suggesting that this will be the only way, or even the most common way, just that it shouldn't be prohibited.

And for something like a physics class, which is presenting complex visual encodings of information, the audio description part might well be something you'd like to skip over when scanning for some specific piece of information. I think the goal here is not to require any specific representation of the information, but to be sure the information is available. I think any "text-based" representation which is an accessible equivalent to the content should satisfy, whether it is a plain text transcript, a marked-up html version of the information that could contain skip links, or a version where there is a web-like representation of the text with links to pieces of the content.

It depends...The end of the movie "Apocalypse Now" had long periods of no dialogue...In that case there would be quite a bit of description between the dialogue... Audio descriptions are limited to the available space between dialogue so they are generally short. In your example of the online professor...the descriptions would be generally very short...especially in a lecture series... and descriptions are limited to the space between the dialogue on the video. I've never seen a professor who doesn't talk much in a class. (oops sorry Gregg :-) ) I would also suggest that the example is not "equivalent" to that of a sighted person but rather "enhanced" because sighted people sit through the descriptions in the video, unless they hit the fast forward button. If we want to create that kind of "enhanced" experience of skipping the descriptions then I suggest put the burden on the person who wants the enhanced experience by putting in "skip description" links (like a skip nav) that the user can use to bounce over the descriptions. (kind of like the sighted person who would have to hit fast forward) That way the default presentation includes the descriptions (without having to bounce around) and the enhanced version allows the user to skip over it with a link.

As a result, while it is fine to say that these different types of information should be mixed together, it may not create the best experience. one method that would allow users to have easy access to the descriptions within a transcript would be to link to the descriptions (the descriptions could be in the same file, or even in a separate file) instead of to include the description text directly. This way, the user could listen to the description if desired, and skipped more easily. The reason I mentioned this was that your suggested rewrite to 1.1.6 could potentially make this technique insufficient to satisfy the requirement, and I want to make sure that this would be allowed. Is that more clear?

For example: Transcript: This is the first spoken transcript text. This is more transcript. (<a href="#desc1">description 1</a>). This is more transcript. Blah blah blah.... Descriptions: <a name="desc1" id="desc1">1. </a>This is the first description This would improve the experience for many users,and while it is untested, I'd like to make sure that it is acceptable to use.
