 1.1.3 Display of Time-Based Media Alternatives:

For recognized on-screen alternatives for time-based media (e.g. captions, sign
language video), the following are all true: (Level AA)## DONE 2 August 2012

a.    Do not obscure primary media: The user can specify that displaying media
alternatives doesn't obscure the primary time-based media; and

b.    Do not obscure controls: The user can specify that the displaying media
alternatives doesn't obscure recognized controls for the primary time-based
media; and

c.    Configurable text: The user can configure recognized text within media
alternatives (e.g. captions) in conformance with 1.4.1.

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.

1.1.4 Default Rendering of Alternative Content (Enhanced):

For each type of non-text content, the user can specify the cascade order in
which to render different types of alternative content when preferred types are
not present. (Level AAA)   

1.1.5 Size and Position of Time-Based Media Alternatives:



The user can configure recognized on-screen alternatives for time-based

media (e.g. captions, sign language video) as follows: (Level AAA)



a.    The user can resize the media alternatives up to the size of the user

agent's viewport.

b.    The user can reposition the media alternatives to at least above,

below, to the right, to the left, and overlapping the primary time-based

media.



Note 1: Depending on the screen area available, the display of the primary

time-based media may need to be reduced in size or hidden to meet this

requirement.



Note 2: Implementation may involve displaying media alternatives in a

separate window, but this is not required.
