équivalent non-textuel

CONT: Alternative Information Content is ""equivalent"" to other content when both fulfill essentially the same function or purpose upon presentation to the user. Equivalent alternatives play an important role in accessible authoring practices since certain types of content may not be accessible to all users (e.g., video, images, audio, etc. . Authors are encouraged to provide text equivalents for non-text content since text may be rendered as synthesized speech for individuals who have visual or learning disabilities, as Braille for individuals who are blind, or as graphical text for individuals who are deaf or do not have a disability. Text equivalents for audio clips are called ""text transcripts"". Captions are essential text equivalents for movie audio. Another essential text equivalent for a movie is a ""collated text transcript."" An essential non-text equivalent for movies is ""auditory description"" of the key graphical elements of a presentation.
