About NCAM • The Media Access Group at WGBH is a non-profit service (offices in Boston and Los Angeles) • The Caption Center (est. 1972) • the world's first captioning agency • makes audiovisual media accessible to audiences who are deaf or hard-of-hearing • Descriptive Video Service (est. 1990) • makes television, film & video accessible to audiences who are blind or visually impaired • The National Center for Accessible Media (est. 1993) • a research, development and advocacy entity • works to make existing & emerging technologies accessible to all audiences • digital television, convergent media, educational technologies, web, multimedia
Access to Locally Televised On-Screen Information • October 2005 – September 2008; extended until September 2009; http://ncam.wgbh.org/onscreen • Exploring solutions to enable local television stations to convey both emergency and non-emergency information in a manner that meets the communication needs of people with sensory disabilities. • Funding provided by the U.S. Department of Education • Partner television station: WCVB; Hearst-Argyle
Project Activities • Develop prototype software to intercept data from various sources, then extract, transform and prepare it for text display or for speech output. • Create demonstration models. • Publish guidelines for local television stations which suggest implementation schemes for various equipment configurations, and provide recommendations for further study.
Rules regarding accessibility of on-screen information • FCC 47 C.F.R. Part 79, established in 2000: • Emergency information that is provided in the audio portion of the programming must be made accessible to persons with hearing disabilities by using a method of closed captioning or by using a method of visual presentation. • Emergency information that is provided in the video portion of a regularly scheduled newscast, or newscast that interrupts regular programming, must be made accessible to persons with visual disabilities.
Rules regarding accessibility of on-screen information • Emergency information that is provided in the video portion of programming that is not a regularly scheduled newscast, or a newscast that interrupts regular programming, must be accompanied with an aural tone. • Emergency information should not block any closed captioning and any closed captioning should not block any emergency information provided by means other than closed captioning.
Rules regarding accessibility of on-screen information • Emergency information should not block any video description and any video description provided should not block any emergency information provided by means other than video description.
Solutions: descriptions • Analog: One stream of additional audio inserted into the SAP channel.
Solutions: descriptions • Multiple streams of information
Solutions: captions • Relocate captions as necessary • software that monitors position of on-screen graphics so that captions may be automatically relocated when there is a conflict between the two elements
How it’s done: captions • Application monitors a scene open in DekoCast • Controls GPI outputs to control an EEG CB412 Caption Data Bridge • CB412 is used to relocate closed caption text away from lines where it would obscure the graphics underneath
Guidelines • Publication of guidelines for local stations that summarize... • how software can be used to prepare data for translation to speech, and inserted into the broadcast stream; • suggestions for an array of implementation schemes for various equipment configurations; • recommendations for further study.
Additional work in accessible alerts • Access to Emergency Alerts, 4-year grant from U.S. Dept. of Commerce; http://ncam.wgbh.org/alerts • United industry and consumers to identify replicable approaches to accessible notification • Resources include: • Information requirements model • Consumer, emergency management & social science research reports • Recommendations to media, government, industry, emergency management and consumers
Excerpted recommendations to media • Produce a library of fully accessible (text, audio, video) emergency messages that can be delivered on-air, via mobile devices, the Web, shown in shelters, etc. • Instruct on-air news personnel to audibly describe what is visually presented (e.g., maps, remote broadcasts, etc.) • Provide captions & audio descriptions for video delivered on the Web • Ensure that broadcasters’ Web sites are fully accessible
