Descriptive Video Works

Described video (DV) is to the blind and vision-impaired what closed captioning is to the deaf. DV provides a descriptive narration of the key visual elements in television programs and other visual media to make them more accessible to people with visual disabilities. On a secondary audio track, a highly trained narrator provides the vocal description of the visuals imparted unspoken action within the natural pauses in the dialogue. A full DV mix consisting of the main program audio combined with these narrated descriptions is accessible through most TVs and VCRs via the secondary audio program (SAP).
