As I finish out this series of tutorials on the 4th Generation Apple TV, I want to focus on the options for customizing the playback of media and the appearance of the interface. As shown in the video, the captions and subtitles feature makes great use of the Siri remote capabilities on the 4th Generation Apple TV: you can either enable the captions for the rest of the program (“Turn on closed captions”), or you can enable them for a short time if you have missed something (just say “What did he/she say?” and after the video rewinds a few seconds the captions will come on for a short time to help you catch what you missed).
Of course this feature will only work if the content creator(s) have made the captions available. Ted Talks is one channel that does, making the great presentations on their channel accessible to a wider audience (yay for Ted Talks!).
Apple TV also supports audio descriptions. Audio descriptions provide a description of the action in a video for those who are unable to see. The audio descriptions can be enabled in the same Media section of the Accessibility Settings where Captions and Subtitles are found. As with captions, these audio descriptions will only work if the content creator has made them available.
In addition to the ways in which viewers can customize media playback, the Apple TV watchOS includes a number of options for customizing the interface: bold text, reduce motion, reduce transparency and focus style, which adds an outline around the currently selected item.
