Captioning is the key to opening up a world of information for persons with hearing loss or literacy needs. There are more than 32 million Americans with some type of hearing loss. Millions of others are illiterate, learning to read, or use English as a second language.
Definition of Captioning
Captioning is the process of converting the audio content of a television broadcast, webcast, film, video, CD-ROM, DVD, live event, or other production into text and displaying the text on a screen or monitor. Captions not only display words as the textual equivalent of spoken dialogue or narration, but they also include speaker identification, sound effects, and music description.
It is important that the captions are (1) synchronized and appear at approximately the same time as the audio is delivered; (2) equivalent and equal in content to that of the audio, including speaker identification and sound effects; and (3) accessible and readily available to those who need or want them.
Broadcast/Webcast Video Captioning for Television or Web Streaming Methods
Methods vary according to when the captions are created and displayed.
Off-line captions are created and added after a production has been recorded, but before it is aired or played.
Examples of productions that utilize off-line captioning are broadcast TV programs, home videos, and educational media. Most of these captions appear in the pop-on style.
On-Line (Real-Time or Live)
On-line captions are created and added during a live broadcast or web stream event. This method is used to describe the captioning of live political debates, sporting events, classroom lectures, business seminars, and other live productions. Most of these captions appear in the roll-up style.
Traditional broadcast television and cable channels have been using broadcast captioning for years to bring television to the Hard of Hearing community and to allow viewers to enjoy programs in noisy or crowded environments.
Government broadcasts like City Council meetings and commission hearings, as well as board meetings, also use broadcast and/or web streaming captioning services to lay text over video.
