Project Home | Detailed Overview | Staff | Samples
Millions of Americans of all ages use cell phones, PDAs or dedicated portable media players to access content related to almost every aspect of daily life. Streaming and downloadable video are gaining popularity in the mobile world, yet the 22 million Americans who are deaf or hard-of-hearing cannot benefit from this content because mobile-video technologies do not address the technical requirements for packaging and delivering captions.
NCAM's Captioning Solutions for Handheld Media and Mobile Devices project will explore and prototype methods for delivering captioned media to mobile devices of all kinds, address the technical requirements for packaging and transcoding captions, and look at ways for users to access and control caption data. See the detailed overview for more information on project activities.
