Closed captioning ( CC ) is a form of subtitling , a process of displaying text on a television, video screen, or other visual display to provide additional or interpretive information, where the viewer is given the choice of whether the text is displayed. Closed captions are typically used as a transcription of the audio portion of a program as it occurs (either verbatim or in edited form), sometimes including descriptions of non-speech elements. Other uses have included providing a textual alternative language translation of a presentation's primary audio language that is usually burned-in (or "open") to the video and unselectable.

This is generally reliable, though errors are not unknown. The National Captioning Institute was created in 1979 in order to get the cooperation of the commercial television networks. The first use of regularly scheduled closed captioning on American television occurred on March 16, 1980. Sears had developed and sold

Through discussions with the manufacturer it was established that the appropriate circuitry integrated into the television set would be less expensive than the stand-alone box, and Ronald May, then a Sanyo employee, provided the expert witness testimony on behalf of Sanyo and Gallaudet University in support of the passage of the bill. On January 23, 1991, the Television Decoder Circuitry Act of 1990

They were working with professor Alan Newell from the University of Southampton who had been developing prototypes in the late 1960s. The closed captioning system was successfully encoded and broadcast in 1973 with the cooperation of PBS station WETA . As a result of these tests, the FCC in 1976 set aside line 21 for the transmission of closed captions. PBS engineers then developed

The ACC, now known as Media Access Australia , sold its commercial captioning division to Red Bee Media in December 2005. Red Bee Media continues to provide captioning services in Australia today.

This technique was developed in the 1970s as an initiative of the BBC 's Ceefax teletext service. In collaboration with the BBC, a university student took on the research project of writing the first phonetics-to-text conversion program for this purpose. Sometimes,

Recorded Teletext caption fields also suffer from a higher number of caption errors due to increased number of bits and a low signal-to-noise ratio , especially on low-bandwidth VHS. This is why Teletext captions were stored on floppy disk, separate from

In the United States, the National Captioning Institute noted that English as a foreign or second language (ESL) learners were the largest group buying decoders in the late 1980s and early 1990s before built-in decoders became a standard feature of US television sets. This suggested that the largest audience of closed captioning was people whose native language

The term subtitle has been replaced with caption in a number of markets—such as Australia and New Zealand—that purchase large amounts of imported US material, with much of that video having had

For home Beta and VHS videotapes, a shift down of this line 21 field must be done due to the greater number of VBI lines used in 625 line PAL countries, though only a small minority of European PAL VHS machines support this (or any) format for closed caption recording. Like all teletext fields, teletext captions can not be stored by

Until the introduction of digital television in 2001, the network was the only domestic television service broadcast by

The words then change to "#OurABC", which was the network's then-new slogan. The "#OurABC" slogan at the end of each ident was changed to "Yours" on 31 December 2017. The 1975 logo

In New Zealand, broadcasters superimpose an ear logo with a line through it that represents subtitles for the hard of hearing, even though they are currently referred to as captions. In the UK, modern digital television services have subtitles for the majority of programs, so it is no longer necessary to highlight which have subtitling/captioning and which do not. Remote control handsets for TVs, DVD players, and similar devices in most European markets often use "SUB" or "SUBTITLE" on

Subtitles assume the viewer can hear but cannot understand the language or accent, or the speech is not entirely clear, so they transcribe only dialogue and some on-screen text. Captions aim to describe to the deaf and hard of hearing all significant audio content—spoken dialogue and non-speech information such as the identity of speakers and, occasionally, their manner of speaking—along with any significant music or sound effects using words or symbols.
