24 Closed Captioning Systems
Captioning, according to the Accessible Media Industry Coalition, is “the process of converting the audio content of a television broadcast, webcast, film, video, CD-ROM, DVD, live event, or other productions into text, which is displayed on a screen or monitor.” Captions not only display words as the text equivalent of spoken dialogue or narration, but also include speaker identification and sound effects. It is important that the captions be
• Synchronized and appear at approximately the same time as the audio is available;
• Equivalent and equal in content to that of the audio, including speaker identification and sound effects;
• Accessible and readily available to those who need them.
