Making Making Video and Audio Accessible
The following resource listings
are arranged alphabetically.
- Adobe resources:
- Adobe Flash captioning from National Center for Accessible Media CC for Flash (http://ncam.wgbh.org/webaccess/ccforflash/) and the
ccPlayer
are free tools to provide captioning for Flash and to playback the captions. These captions are read from external files formatted in the W3C's DFXP format which can be created with MAGpie, NCAM's free captioning application. CC for Flash also imports Apple's QTtext format for use within the application. QTtext files can be created by professional caption authoring tools, or as an output from CaptionKeeper or MAGpie. Any content can display captions in Flash using the CC for Flash component with a QTtext file or a DFXP file (see W3C's DFXP format).
- Caption Keeperhttp://ncam.wgbh.org/webaccess/captionkeeper/index.htmlCaptionKeeper is a software program which converts television-based closed-caption data into web streaming formats. It takes closed-caption (line-21) data as input, and creates simultaneous outputs suitable for live and archived multimedia presentations in RealPlayer™, Windows Media™ Player and QuickTime™ Player formats.
- Captioning
Quicktime (http://www.webaim.org/howto/captions/quicktime/quicktime)This article talks about Quicktime specifically but also does an excellant
overview on the state of synchronized multimedia. Detailed article that gives
step-by step instructions to add captioning to Quicktime movies- clear enough
even for first timers!
- High Tech Training Center Unit
- Rich
Media Accessibility (http://ncam.wgbh.org/richmedia/showcase.html)
Rich media refers to elements on a web page (or in a separate player) which
exhibit dynamic motion over time or in response to user interaction. Contains
examples of accessible rich media, information about available tools for rich
media, links to a range of relevant resources, and discussion about multimedia
access issues and solutions; and research findings from annual focus groups
with Web users that are visually impaired and with Web users with auditory
impairments. Great site with lots of information. Media Access Generator
(MAGpie) is downloadable from this site.
- SMIL:
Synchronized Multimedia Integration Language (http://www.w3.org/AudioVideo/)
To enable simple authoring of TV-like multimedia presentations such as training
courses on the Web, W3C has designed the Synchronized Multimedia Integration
Language. The SMIL language is an easy-to-learn HTML-like language.
Streaming
Media World (http://www.streamingmediaworld.com/)
Offers lots of information on SMIL and other non-SMIL synchronizing languages.
Tutorials are also available.
- Synchronized
Accessible Media Interchange (SAMI) http://www.msdn.microsoft.com/library/default.asp?url=/library/en-us/dnacc/html/atg_samiarticle.asp
Microsoft® Synchronized Accessible Media Interchange (SAMI) simplifies captioning
for developers, educators, and multimedia producers and designers who will
now find it easier to make their work more universally accessible. The SAMI
file format specification is available to the public as an "open" (no licensing
fees) standard.
