Abstract: Captioning for the deaf has now reached the operational phase after more than seven years of development at the Public Broadcasting Service (PBS). In December 1976, following two years of field testing, the FCC authorized the use of line 21 of the vertical blanking interval for the transmission of captioning data. Texas Instruments has developed customized integrated circuits for the captioning decoders. Sears, Roebuck & Co. is manufacturing the home decoders through Sanyo, which manufactures television sets for Sears. Sears is also marketing and servicing the home decoders. Programs will be captioned for public and commercial broadcasters by the National Captioning Institute. The decoders became commercially available in March 1980, and the captioning operation was ready at that time. Work continues on other technical developments related to captioning, such as a universal time code for film, which will enable films, as well as videotapes, to be captioned.
