WCAG 2.0 is clear about the need to add both captions and descriptions to multimedia; however, the requirements do not offer basic advice on how captions and descriptions should be authored and delivered. Guidelines for multimedia accessibility do exist but they are usually targeted at specific technology or regions (see partial listing below). We propose that WCAG 2.0 include a neutral set of techniques documenting best practices for how captions and descriptions should be created and integrated into multimedia in order to best meet WCAG requirements. ================== Creating Accessible iTunes U Content: http://deimos3.apple.com/WebObjects/Core.woa/Browse/wgbh.org.2010579900 Effective Practices for Description of Science Content within Digital Talking Books: http://ncam.wgbh.org/experience_learn/educational_media/stemdx Authoring Captions for Flash: http://ncam.wgbh.org/invent_build/web_multimedia/tools-guidelines/authoring-captions-for-flash Captioning Key: http://www.cfv.org/caai/nadh7.pdf Suggested Styles and Conventions for Closed Captioning (Media Access Group at WGBH): http://main.wgbh.org/wgbh/pages/mag/services/captioning/faq/sugg-styles-conv-faq.html IBM Web Checklist (Checkpoint 1.2a: Captions): http://www-03.ibm.com/able/guidelines/web/webcaptions.html IBM Web Checklist (Checkpoint 1.2b: Descriptions): http://www-03.ibm.com/able/guidelines/web/webaudiodescriptions.html G3ict e-Accessibility Policy Toolkit for Persons with Disabilities: http://www.e-accessibilitytoolkit.org/toolkit/technology_areas/television WebAIM Web Captioning Overview: http://webaim.org/techniques/captions/
