Closed captioning is the process whereby captions are converted to electronic codes and inserted in the regular television signal, specifically on Line 21, a portion of the picture normally not seen.
Employers often use videotapes as training tools for employees.
When tapes are used that have not been captioned, the tapes are inaccessible to employees who are deaf or hard of hearing. Employers should make an effort to ensure that all employees can benefit from training tools. When purchasing training tapes, consider purchasing tapes that have either open or closed captions or contact captioning service providers that can add captions to training videos. Employers might also use captioning as a way to provide realtime communication access to meetings, special events and web casts. Many captioning providers offer remote CART and Internet captioning where the stenographer is not physically present at the event.
