Captioning shows the text version of spoken words and other sounds on TV, webcasts, films, DVDs, live events, and more. It includes not just the dialogue, but also who is speaking, sound effects, and music descriptions.
Closed captioning means you can turn it on or off yourself, while open captioning is always on. Real-time captioning is used for live events or presentations. Hawkeye can provide captioning for both recorded materials and live events.
