Phill, if you are just reading it then that is the case. However for people who have marinal hearing, having the sound and the captions/score available and synchronisd is more valuable than one or the other (similarly for people who can hear, but have difficulty reading). One of the challenges we face is that there are people who are looking for mulit-modal support - there are more paople with poor hearing than there are with no hearing (and similarly for other disabilities).

In other words, say there is an audio file of a musical song, isn't reading the musical score, with the words, more accessible than a empty (remember there is no video in this example) view with some caption text popping up now and then? Regards, Phill Jenkins, Bruce Bailey <bbailey@clark.net> on 12/10/99 05:01:14 PM Please respond to "webmaster@dors.sailorsite.net" <webmaster@dors.sailorsite.net> I respectfully disagree. Reading synchronized captions is MUCH easier and MUCH more functional than referring to a separate transcript. So much so that P2 might even be too LOW. Think of this from the perspective of a person who is deaf and who is quite comfortable with (closed) captions on television. I also have to say again that if (1) one's video is already in "Real Player G2" format (very popular), and (2) you already have a text transcript, then (3) creating synchronized captions (via SMIL) is VERY easy. If anyone cares to provide an example (1) and a corresponding (2), I would be pleased to volunteer creating (3). -- Bruce Bailey On Friday, December 10, 1999 4:05 PM, pjenkins@us.ibm.com [SMTP:pjenkins@us.ibm.com] wrote: > I would argue that even priority 2 is too high.
