Action 1047 follows – if the second example for 1.1.5b doesn't work we 
can leave it out.

Cheers,
Kim

ACTION-1047 - Split 1.1.5 so that the first two bullets are a and the 
third bullet is aa. ier and handles must be split as well. [on Kimberly 
Patch - due 2014-11-04].

*SUGGESTED CHANGES*


1.1.5a

For recognized 
<http://w3c.github.io/UAAG/UAAG20/#def-recognize>on-screen alternative 
content for time-based media (e.g. captions, sign language video), the 
following are all true: (Level A)

  * Don't obscure controls:Displaying time-based media alternatives
    doesn't obscure
    <http://w3c.github.io/UAAG/UAAG20/#def-obscure>recognized controls
    for the primary time-based media.
  * Don't obscure primary media:The user can specify that displaying
    time-based media alternatives doesn't obscure the primary time-based
    media.

  * Note: Depending on the screen area available, the display of the
    primary time-based media may need to be reduced in size to meet this
    requirement.

Intent of Success Criterion 1.1.5:

Users who require or can benefit from alternative media tracks in video 
or audio might find that the default or authored position and size of 
those tracks is unusable. Enabling the user to move and scale any 
displayed alternate media tracks (e.g. captions) allows displayed 
content to be positioned and sized to meet the needs of the user.

Examples for Success Criterion 1.1.5:

  * Jaime is deaf and is taking courses from on online university. She
    prefers to use ASL if it is available for online media. A course she
    is taking offers captions and a signing avatar for the recorded
    lectures. The default size of the avatar window is small, making it
    difficult to follow the signing. The avatar also overlays a
    significant part of the lecture video. Jaime drags the avatar out of
    the video and enlarges it, so that they are side by side and equally
    sized.
  * [mobile] Jaime is deaf and prefers to always display captions on her
    mobile phone. She has set her global settings on the phone to turn
    on closed captions. All videos displayed on the phone will
    automatically display captions.
  * [mobile] Ben has low vision that becomes worse throughout the day as
    he becomes more tired. He keeps a floating control on his mobile
    phone that allows one touch access to his configuration so that he
    can change the font size. The floating control can be easily moved
    around the screen so it is not in the way of other controls, and it
    becomes translucent after it is idle for a few seconds.

1.1.5b

For recognized 
<http://w3c.github.io/UAAG/UAAG20/#def-recognize>on-screen alternative 
content for time-based media (e.g. captions, sign language video), the 
user can configure recognized text within time-based media alternatives 
(e.g. captions) in conformance with 1.4.1 
<http://w3c.github.io/UAAG/UAAG20/#sc_141>.

  * Note: Depending on the screen area available, the display of the
    primary time-based media may need to be reduced in size to meet this
    requirement.

Intent of Success Criterion 1.1.5:

Users who require or can benefit from alternative media tracks in video 
or audio might find that recognized text displayed within alternate 
media tracks is unusable due to its configuration. Enabling the user to 
configure alternate media tracks (e.g. captions) allows content to be 
displayed in a way that meets the needs of the user.

Examples for Success Criterion 1.1.5:

  * Justin has low vision and works in a noisy environment that makes it
    difficult to listen to instructional videos. When he enlarges the
    text of the captions to a viewable size, they block most of the
    video image. When he is using his tablet, Justin selects an option
    that displays the caption track in a separate window, which he
    positions below the video image so the captions don't block the
    video image.

  * Justin has low vision and works in a noisy environment that makes it
    difficult to listen to instructional videos. When he enlarges the
    text of the captions to a viewable size, they block most of the
    video image. When he is using his smart phone, Justin selects an
    option that causes the video to pause when the caption track comes
    on so he can read it, then turns the caption track off so he can see
    the video using the full screen.


*ORIGINAL*

1.1.5 Facilitate Clear Display of Alternative Content for Time-based Media:

    for the primary time-based media.
  * Don't obscure primary media:The user can specify that displaying
    time-based media alternatives doesn't obscure the primary time-based
    media.
  * Use configurable text:The user can configure recognized text within
    time-based media alternatives (e.g. captions) in conformance with
    1.4.1 <http://w3c.github.io/UAAG/UAAG20/#sc_141>.
