Accessible supplemental materials delivered with video

Apologies for the cross-posts.

With funding provided by the Reader's Digest Partners for Sight Foundation, the National Center for Accessible Media at WGBH (NCAM) has begun experimenting with the Popcorn.js HTML5 Media Framework to deliver screen-reader accessible supplemental materials alongside video embedded in a Web page.  You can read about the project and see our first prototype demonstration at http://ncamftp.wgbh.org/rd/hgp/ .  Read the instructions and system requirements, then watch the video to see (and hear) accessible Wikipedia entries, glossaries and images with long descriptions displayed as the video progresses along its timeline.

There are links on the site for feedback; we encourage you tell us what you think of what we've done so far.  New demos will be uploaded shortly.

Thanks very much.
