What is the difference between “Real-time and “Off-line” captions?
Off-line captioning is a process of adding captions to a pre-recorded video. Experienced captionists listen to the video and transcribe the dialogue, breaking the transcript into captions on the screen. These captions are time coded on the screen and the resulting data is encoded into the video signal. Real-time captioning is the process of creating captions for live events and live videos. During the live broadcast, specially trained court reporters called real-time captionists, transcribe the audio portion of the teleconference, television program, meeting or other live event. This technique is also called “live display captioning. Example of this service is used on news and sporting events.
