Realtime captions are performed by stenocaptioners, who are court reporters with special training. They use a special keyboard (called a "steno keyboard" or "shorthand machine") to write what they hear as they hear it. Unlike a traditional "QWERTY" keyboard, a steno keyboard allows more than one key to be pressed at a time. The basic concept behind machine shorthand is phonetic, where combinations of keys represent sounds, but the actual theory used is much more complex than straight phonics. Stenocaptioners are capable of writing at speeds of up to 250 words per minute, or even faster in short bursts. The steno then goes into a computer system, where it is translated into text and commands. The captioning software on the computer formats that stream of text into captions, and sends it to a caption encoder. This can be done either directly, or over the telephone using modems. http://www.robson.org/capfaq/online.html
