Hello to all.
My name is Cláudio Esperança and I'm a web developer at Learning Distance
Unit of Institute Polytechnic of Leiria. Our unit is responsible for
planning, design and construct degree courses based on e-learning to our
schools. The accessibility and digital inclusion is extremely important to
us and we believe that the work of this mailing list (that we encountered a
few days ago) may provide us excellent tools to build more and better
courses for all.
While we do not have time to read all the archived discussion on this list
and all articles of the wiki (and even at the risk of going to propose
things that have been suggested or that not make any sense), I would expose
some of my ideas and to hear your comments.
First, some considerations: as I said at the beginning of the message, I am
a web developer and I have very little experience in subtitling, so my
producer. This means that I cannot guarantee the validity or the
implementing possibility of these sugestions.
My first suggestion is: why not allow the association of multiple audio
tracks to a video file? The aim would be to have a video that could be
accessible through various languages, or have multiple audio descriptions.
This association could be made using the tag audio html5, with syntax such
<video id="test" src="..."/>
<audio id="audio1" for="test" lang="en" src="audio1..."/>
<audio id="audio2" for="test" lang="pt" src="audio2..."/>
The great advantage of this syntax is that the audio could be linked to
other elements such as images, for example:
<img id="image1" src="test.jpg"/>
<audio id="audio1" for="image1" lang="en" src="audio1..."/>
<audio id="audio2" for="image1" lang="pt" src="audio2..."/>
This will allow you to add audio descriptions to various HTML elements.
If we forgot about other HTML elements, then the syntax in the case of video
would be something like:
<video id="test" src="...">
<audio id="audio1" lang="en" src="audio1..."/>
<audio id="audio2" lang="pt" src="audio2..."/>
(We could even go further and create an audio format that works as the
subtitles do, which means that a sound clip can start from a certain point
and ends after x time. Would also be interesting to stop a video for hear an
audio description of what happened or what is going to happen - on other
hand, maybe this kind of work must be done in the production of the video
and not in its reproduction.)
In the early discussions of this list is the sign language, as one of the
possibilities of "subtitling" videos. This idea was dropped? I ask this
because the way I understand it, one of the mechanisms of subtitling uses
divs, right? We can't use a similar method to provide a small video with the
sign language representation of what is on the video?
Comments, other suggestions?!?
