Closed Captioning and Audio Description

What is Closed Captioning?

Closed captioning is the process of taking an audio track, transcribing it to text, and then synchronizing it with the media so that the text can be viewed at the same time that the words are being spoken. Closed captions are typically located underneath the video or overlaid on top of the video. Closed captions communicate all audio information, including sound effects and non-speech elements.

What is Audio Description?

Descriptions make television programs, feature films, DVDs, museum exhibits, theme park attractions and other visual media accessible to people who are blind or visually impaired by providing descriptive narration of key visual elements. Key visual elements include actions, costumes, gestures and scene changes which, when described, engage a viewer who is blind or visually impaired with the story.
