Closed captioning allows persons with hearing disabilities to have access to television programming by displaying the audio portion of a television program as text on the television screen.
Closed captioning provides a critical link to news, entertainment, and information for individuals who are deaf or hard-of-hearing. For individuals whose native language is not English, English language captions improve comprehension and fluency. Captions also help improve literacy skills.
Descriptive Video Service (DVS) is a national service that makes Public Broadcasting Service (PBS) television programs, Hollywood movies on video, and other visual media accessible to people who are blind or visually impaired. DVS provides narrated descriptions of the key visual elements without interfering with the audio or dialogue of a program or movie. The narration describes visual elements such as actions, settings, body language and graphics.
