All television advertising must include closed captioning.




Captions enable the soundtrack of a television program, commercial, DVD or video to be read. Unlike foreign language subtitles, which are a translation of the dialogue only, captions include other elements of the soundtrack such as sound effects and music. They are also coloured and positioned on screen to help the viewer follow who is speaking. Closed captions can be switched on or off by the viewer.
