What is Closed Captioning?
Closed captioning provides deaf and hearing-impaired viewers with the text of what is being spoken on television. The text is usually shown in a black box at the bottom of the picture. Hearing-impaired viewers will be familiar with current analogue captioning which can be received on analogue receivers with teletext capability. Captioning is normally closed to viewers but can be accessed by those who need it. Closed captioning of programming for hearing impaired viewers will be done for all English language news and current affairs programs as well as for all prime time programs (6.00pm to 10.30pm).
Closed captions are sent at the same time as the program by the channel. This means that the closed-captioning service is at the discretion of the channel and/or program. Information affecting closed-captioning passes through “line 21,” an invisible line on your TV screen (at the very bottom of your screen). To decode this line, your TV must have a built-in closed-caption decoder. The Videoway terminal also incorporates this function with the telematic option. What Captioning Is and Who Uses It Captioning is the transcription and display of dialogue and other auditory information, such as on- and off-screen sound effects, music, and laughter. Captioning benefits more than a person who is hard-of-hearing. In loud or crowded exhibition halls, [restaurants and bars], captioned videos allow sighted visitors to read what they cannot hear. Captions also benefit new readers and people who are learning English as a second language. Terminology Open captions appear on-screen, whereas closed cap
Closed captioning is a technique used to display text on a television screen by request from the viewer. The “closed” is a reference to the fact that the captions must be “opened” or unlocked by the viewer, in contrast with open captions, which are always on display. Closed captioning is used most commonly by the deaf and hard of hearing, although anyone is welcome to use it. For instance, closed captioning can be useful when someone wants to watch television on a low volume setting without disturbing others, as it ensures that the viewer does not miss important dialog. In some nations, there is a distinction between captions and subtitles. Captions record the speech on screen along with any notable information like sounds, while subtitles translate the speech on screen, assuming that the viewer does not understand what is being said. While both appear in the form of text on the screen, they have different functions. Some people call translations and transcriptions “subtitles,” which c
Closed captioning is an assistive technology designed to provide access to television for persons with hearing disabilities. Through captioning, the audio portion of programming is displayed as text superimposed over the video. In 1990, Congress first required television receivers to contain circuitry designed to decode and display closed captioning. As of July 1993, the Commission has required that all analog television sets with screens 13 inches or larger sold in the United States contain built-in decoder circuitry that allows viewers to display closed captions. Beginning July 1, 2002, the Commission also required that digital television (DTV) receivers include closed caption display capability.
Closed captioning is an assistive technology designed to provide access to television for persons who are deaf and hard of hearing. It is similar to subtitles in that it displays the audio portion of a television signal as printed words on the television screen. Unlike subtitles, however, closed captioning is hidden as encoded data transmitted within the television signal, and provides information about background noise and sound effects. A viewer wishing to see closed captions must use a set-top decoder or a television with built-in decoder circuitry. Since July 1993, all television sets with screens thirteen inches or larger have had built-in decoder circuitry. Q: Who is required to provide closed captions under the new rules? A: The rules require people or companies that distribute television programs directly to home viewers (“video program distributors”) to make sure that those programs are captioned. Video program distributors include local broadcast television stations, satellit
