Re: Review this week: Media Accessibility User Requirements

This is level 1.

In 3.2:  Add specific information for low vision display

ORIGINAL TEXT: ... . [TVD-1] Support presentation of text video
descriptions through a screen reader or braille device, with playback
speed control and voice control and synchronisation points with the
video.
CHANGE TO: Support presentation of text video descriptions through a
screen reader,braille device [and/or] modified print for low vision]
with playback speed control and voice control and synchronisation
points with the video.

ORIGINAL TEXT:... . [TVD-2] TVDs need to be provided in a format that
contains the following information:
start time, text per description cue (the duration is determined
dynamically, though an end time could provide a cut point)
possibly a speech-synthesis markup to improve quality of the
description (existing speech synthesis markups include [SSML] and
[Speech CSS]) accompanying metadata providing labeling for speakers,
language, etc.
ADD AT END: ...labeling for speakers, language, etc.
[visual style specifications CSS for individual needs of visual
readers with low vision. [Font-size, color (back and fore), Font
Family, spacing (line, letter and word) as described in ]

Please apply the same to 3.3 Enhanced Video Discription, 3.9 Transcripts.

Use Cases for VD and EVD: When viewing a lecture writing on the
blackboard is often difficulty to see.  It is video of text and has
all the graininess issues of any text in a picture.  Actually is worse
than still text in a picture.  Having blackboard / whiteboard
information in accessible text is essential to following the lecture.

Use Case for Transcripts:  The transcript is essential for review:
Again take the lecture or any other instructional presentation
setting.  Gathering all the audio and video innformation usually takes
more time with partial sight then the lecture time permits.  A
transcript in accessible print permits self paced access to the
information.
