Captioning frequently asked questions

What is the difference between closed captions and subtitles?

Captioning is the text version of speech and other sounds, displayed on-screen. Captions are generally intended to assist viewers with a hearing impairment. Closed captions are described as ‘closed’, because they are not displayed unless the viewer chooses to turn them on.

Subtitles display what is being said on screen. They are commonly used to translate one language spoken on-screen into another language.

Do free to air multi-channels have to be captioned?

Broadcasters are only required to provide a captioning service for programs transmitted on their multi-channels (channels other than their main channel) if the program has previously been broadcast with captions on their main channel or another multi-channels.

Is catch-up TV captioned?

Catch-up TV, which is a type of video on demand, is not required by the Broadcasting Services Act 1992 to be captioned, however some free-to-air broadcasters have begun captioning their catch-up services.  If captions are available on a catch-up program, you can click on the captioning button on screen to reveal them.

Do advertisements have to be captioned?

Advertisements are not required to be captioned under the Broadcasting Services Act 1992.

Why do my captions occasionally appear garbled or frozen?

When words appear garbled, jumbled or frozen on the screen, or if lines of captioning are not displaying properly, this may be due to connection or reception problems. Captions are transmitted to your television the same way programs are, so if there is a problem with the reception or internet connectivity of your programs, your closed captions may be affected.

If you’re having problems with your TV reception, visit our What’s wrong with my TV reception? webpage for advice.

Why do lines of captions sometimes appear all at once, and sometimes word by word?

When a line or two of captions appear all at once, it is known as block captioning. This is often used when captions for a program have been prepared ahead of the time it is broadcast.

When captions appear one word after the next, they are known as scrolling captions. They are usually used when captions are being created live, as the program is broadcast. The captions are transmitted to appear on your TV screen as the captioner speaks or types each word.

What do different coloured captions mean?

Captioners will distinguish different speakers by using different colours. However, the same colour may not always be used for a particular speaker. The colour will depend on the number of speakers and the number of colours available.

Why are there dashes (--) in captions?

When a captioner makes an error they may indicate that a mistake has been made with two dashes (--) and correct the mistake. The correction may not appear where the mistake was made but may appear a few words after, so it may appear out of context in the sentence.
