Hi Sunyang,

I expect there will be 3 Change Proposals to choose between: the two you
mention[1][2], and a third (Silvia's "Introduction of a @transcript=URL
attribute" proposal)[3].

[yang] Ok, I see, I think both 2, and 3 are possible, so can we have a harmonized solution include both, because both seem reasonable ? Or we have to choose between them? I see you are Silvia are editors of proposal 1 to defer it, while Silvia is editor of proposal 3 to adopt it using transcriptURL,

Right, the [1] proposal advocates deferring the addition of a mechanism
for programmatic association of transcripts with media elements in HTML
to HTML.next.

> And the transcript will be integrated with media element, right?

Yes, the [2] and [3] proposals advocate such a feature, though with a
somewhat different design.

I assume you're referring to [2]. This is a proposal for ISSUE-194, not
for ISSUE-203.
[yang] no I am reference to http://www.w3.org/html/wg/wiki/ISSUE-194/Research#2C_-_aria-describedby


< video src=video.mp4 aria-describedby="foo"></video>
<a href=transcript.html hreflang=en
   id=foo>English language transcript</a>

but I know they are different, 194-2C talking about using aira-describedby , but al/longdesc just a paragraph of text.

I'm not sure what you're quoting here. I think you're referring to how
the proposal at [1] mentions that authors can currently use a
combination of WAI-ARIA attributes and RDFa or Microdata to mark up
transcript links. I don't think I understand the question.

[yang] Sorry, I realize that you are ted ;), and right this is option 1 in the list. Ignore my question.

Both nonzero-edit proposals ([2] and [3]) allow for linking to HTML or
text files, regardless of what server is hosting what.

Any method of indirection will be more complex than a direct link, but
there are several other design considerations that argue for using an
indirect link for these use cases, as I argue in [2].

[yang] yes, indirect link is good for UA not support video element.
      But as I know in fact every browser now have support video element.
      So I still think indirect link is more complex.

I hope the text of all three change proposals is clear enough to
establish the design tradeoffs of the different approaches. If it's not,
please provide feedback so Silvia and/or I can improve our proposals!

[yang] I think we should firstly decide whether or not we need this feature, then
We will select between [2][3] or combine them. So people have already support do it
In HTML5?


Thanks,
Ted
