Original wording: 2.11.11 Scale and position visual alternative media tracks: The user can scale and position alternative media tracks independent of base video. (Level AAA) Mark's proposed: http://lists.w3.org/Archives/Public/w3c-wai-ua/2012AprJun/0143.html 2.11.11 Scale and position visual alternative media tracks: The user can scale and position alternative visual media tracks independent of the base video or audio player presentation. (Level AAA) Thoughts: 1. Captions and sign language video seems like it belongs under Principle 1 (Perceivable) rather than Principle 2 (Operable). Maybe under GL1.1. 2. Should we use the WCAG 2.0's terminology: " Time-based Media"? 3. What about color, etc. of caption text? I think 1.4.1 covers it, but would benefit from an example and possibly an SC note. So perhaps... 1.1.X Time-Based Media Alternatives: The user can configure any or all of the following for visually-rendered time-based media alternatives (e.g. captions, sign language video): (a) Scale: to at least 500% of the default size. (b) Position: the media alternative so that it does not obscure the primary time-based media or its controls. The user can scale and position alternative visual media tracks independent of the base video or audio player presentation. (Level AAA) Ed. This stem is very close to the current stem of 1.1.3 which might be changed to "Alternative Content Cascade". Cheers, Jan
