Closed Captions vs Open Captions

The term ‘closed captions’ is widely recognised as referring to onscreen text displayed on television and video services. This definition covers the ‘captions’ aspect of the terminology, but what is the difference between ‘open’ and ‘closed’ captions?

Open captions are always visible on a video. An open captions file is effectively burned onto the video stream, similar to subtitles, and is no longer recognisable as a text file. This can potentially mean a loss of quality when video files are compressed.

Closed captions require a viewer to turn on the text, which is encoded into Line 21 of the television signal. The text file is preserved and kept separate from the video stream. Consequently the viewer takes on responsibility of knowing how to turn on closed captions on their television set.
