Captioning comes in two forms: opened and closed. Closed captions (CC) are the most common. SBS defines closed captions as captions that can be hidden (thus closed), until ‘opened’ by the viewer. Essentially, CC can be turned on or off.Open captions have the same content as closed captions, except open captions are permanent and cannot be turned off. Whether captions are open or closed, the media producer has control over the way captions appear. This includes the location of captions, size, font, colour and duration.Subtitles are generally applied to translated dialogue for media in foreign languages. In contrast, captions include descriptions of important non-dialogue audio like “music” or “sighs”. Many countries legally require both live and pre-recorded television programs to be CC.- CENTRE FOR ACCESSIBILITY AUSTRALIA |
