RE: [WSG] Audio and Video
Hello Gian, Thanks for taking the time to provide such a comprehensive answer. It has really helped me focus on what needs to be done. Thanks also for the offer of further help - it is truly appreciated. Kind regards, Elaine http://www.webdandy.co.uk -Original Message- From: listdad@webstandardsgroup.org [mailto:[EMAIL PROTECTED] On Behalf Of Gian Sampson-Wild Sent: 13 November 2006 23:31 To: wsg@webstandardsgroup.org Subject: Re: [WSG] Audio and Video Hi Elaine The W3C Web Content Accessibility Guidelines, Version 1.0 have a number of Level A checkpoints when it comes to audio and video: Checkpoint 1.1: Provide a text equivalent for every non-text element (e.g., via alt, longdesc, or in element content). This includes: ... applets and programmatic objects, ... scripts, ... sounds (played with or without user interaction), stand-alone audio files, audio tracks of video, and video. Checkpoint 1.3: Until user agents can automatically read aloud the text equivalent of a visual track, provide an auditory description of the important information of the visual track of a multimedia presentation. Checkpoint 1.4: For any time-based multimedia presentation (e.g., a movie or animation), synchronize equivalent alternatives (e.g., captions or auditory descriptions of the visual track) with the presentation. Essentially these three checkpoints mean that you need to: - provide an HTML transcript of the relevant file (Checkpoint 1.1) - provide captions for a video file (Checkpoint 1.3) - provide audio descriptions for a video file (Checkpoint 1.4) 1. Provide an HTML transcript of the file This is pretty easy for audio files: just transcribe what was said and who said it, along with any relevant background noise. With video files, you also need to transcribe any actions or events in the video that are relevant (eg. whether it is day or night, car accidents etc) 2. Provide captions for a video file Captions are used for people that are deaf and should therefore include not only what is said but also any noise that is relevant (eg. car backfiring, gunshot etc). Captions are *not* subtitles: subtitles interpret only spoken words. You can caption with MAGpie: http://ncam.wgbh.org/webaccess/magpie/magpie_help/install.html and they also have some handy captioning instructions: http://ncam.wgbh.org/webaccess/magpie/magpie_help/#captioning as does WebAIM: http://www.webaim.org/techniques/captions/magpie/version2/ The University of Wisconsin has some information on merging captions with a video file: http://streaming.wisconsin.edu/accessibility/magpie_tutorial/quicktime.html 3. Provide audio descriptions Audio descriptions are used by people that are blind and should therefore describe, in full, what is visually seen in the video. You can create audio descriptions with MAGpie and they also have instructions on how to do so: http://ncam.wgbh.org/webaccess/magpie/magpie_help/#audiodescription Joe Clark has also written some guidelines on providing audio descriptions: http://joeclark.org/access/description/ad-principles.html Skills for Access have some information on using MAGpie: http://www.skillsforaccess.org.uk/howto.php?id=135 and providing audio descriptions: http://www.skillsforaccess.org.uk/howto.php?id=104 I have some experience with HTML transcripts, captions and audio descriptions. I am more than happy to help further.

Hi Elaine The W3C Web Content Accessibility Guidelines, Version 1.0 have a number of Level A checkpoints when it comes to audio and video: Checkpoint 1.1: Provide a text equivalent for every non-text element (e.g., via alt, longdesc, or in element content).
