Closed captions not adaptable
Where ICT displays captions, it MUST provide a way for the user to adapt the displayed characteristics of captions to their individual requirements, except where the captions are displayed as unmodifiable characters (e.g. open captions).
People who are deaf cannot hear the audio of multimedia (audio-video) content. In order to give people who cannot hear access to the information conveyed by the audio content, synchronized captions must be provided. Giving people the ability to modify the appearance of captions ensures that more people with varying vision abilities can see the captions.
Fix this issue by ensuring that the video player provides a way for the user to adapt the displayed characteristics of captions to their individual requirements. For example users can change: the color of subtitles, font type, size, opacity of the background box of subtitles, and the contour or border of the fonts.
