my comments preceded by ja: ja: In reviewing section 5 for SMIL/multimedia accessibility I had one major question. Is a plugin (SMIL player, shockwave, insert your favorite plugin here...) a user agent? I have always assumed that a plugin was a user agent and would conform to user interface accessibility as well as other appropriate guidelines. But, the UA guidelines do not specifically address this point. 5.1.10 [Priority 1] Allow the user to control the position of captions. ja: Captions are not one size fit all, in addition to caption placement there is a need for 5.1.10.1 [Priority 1] Allow the user to override font family of the caption. 5.1.10.2 [Priority 1] Allow the user to override font size of the caption. 5.1.10.3 [Priority 1] Allow the user to override foreground color of the caption. 5.1.10.4 [Priority 1] Allow the user to override background color of the caption. 5.2.6 [Priority 1] Allow the user specify that captions for video be rendered at the same time as the video. ja: Similar to audio tracks, captions may be available in different languages. There is a need for 5.2.x [Priority 1] Allow the user to choose from among available caption tracks. 5.2.7 [Priority 2] Allow the user specify that audio descriptions of video be rendered at the same time as the video. ja: In discussion with the folks a WGBH, it was recommended that this checkpoint be changed to a Priority 1. Scenario-video showing professor writing complex equations and graphs on the overhead and discussing them but not describing what he/she actually wrote on the overhead. Without description this would be inaccessible to people with visual impairments. This could be generalize to any video presentation of visually rich or complex information where the visually presented information is critical to the understanding of the presentation. ja: additionally, there may also be description tracks in different languages, there is no evidence of this yet so a Priority 2 is recommended. So there is a need for 5.2.x [Priority 2] Allow the user to choose from among available audio description tracks.
