Closed Caption and SDH Support
Apple TV supports closed captioning, so those who are deaf or hard of hearing can fully enjoy TV episodes and thousands of movies. Just look for the CC or SDH icon when buying or renting movies or buying TV shows from the iTunes Store. You can even customize captions with different styles and fonts.
Quickly turn closed captions on and off using the Accessibility Shortcut. Once the shortcut is enabled in Apple TV, you can simply triple-click the Menu button to access your preferred accessibility features.
