label: Description (Brief)
content: Telecaptioning is a method of making the audio tracks of television programs and video recordings accessible for people with hearing impairments. Telecaptioning (also called Closed Captioning) required several steps, technical, economic, and political, in order to be successfully implemented. A set of standards was required so that the telecaptioning decoders would function with any manufacturer’s TV receiver without excessive modification or interference with the operation of the receiver. A set of procedures was needed so that programs’ audio tracks could be transcribed (a task that required people to physically type the transcriptions), which required funding and coordination with content producers. Federal government interest in making this service available required political intervention, in this case resulting in the establishment of the non-profit National Captioning Institute (NCI) in 1979. This unit was donated by the family of John E. D. Ball, the founding president of the National Captioning Institute.
label: Description (Brief)
content: Development of telecaptioning occurred during the 1970s and regular broadcasts of selected programs began in 1980. Since that time, technical advances have produced several generations of increasingly affordable and capable telecaptioning decoders. Ultimately, these devices shrank to the size of computer chips that could be installed in TV receivers during the manufacturing process. In addition to enabling access for people with hearing impairments, telecaptioning has been used to advance literacy among both native and non-native language speakers.
