Audio Description

Audio Description (also known as  Video Description) provides  equal access to television,  recorded video,  and film programming for people who are blind or have low vision.  Through a detailed process that provides concise yet vivid descriptions of a program’s visual elements  during pauses in the dialogue, NCI Audio Description helps people who are visually impaired to “paint a picture” in their minds of those images that others may take for granted. The descriptions are combined with the original sound track on the SAP (Secondary Audio Programming) channel of televised programming or as a separate sound track on other media.
