The Meanings of CC, AD, SDH Icons in iTunes Store
iTunes Store is one of the most successful online market for movies and TV shows, many iPhone, iPad, Windows or Mac users purchase movies or TV episodes, or rent movies from iTunes Store. When browsing iTunes Store, if you click a movie or an episode for detailed information, usually you may find some icons like CC, AD and SDH under movie name or episode name.

Consider that there are some people who are suffering from the impairment of hearing or seeing, Apple add CC, AD and SDH to movies and TV shows to help those people to better understand and enjoy.
What is Audio Descriptions and How to Enable Audio Descriptions
Audio description, also referred to as a video description, described video, or more precisely called a visual description, is an additional narration track intended primarily for blind and visually impaired consumers of visual media (including television and film, dance, opera, and visual art). It consists of a narrator talking through the presentation, describing what is happening on the screen or stage during the natural pauses in the audio, and sometimes during dialogue if deemed necessary.

The Difference between Subtitles, Closed Captioning and SDH
Subtitles are the presentations added to a video, a DVD or a Blu-ray. Subtitles will be displayed on the screen in the text form. Subtitles are mainly for people who do not understand the primary language in which the audio presentation is made or sometimes for people who are unfamiliar with different accents of same language.
Closed Captionings are delivered through a decoder entrenched in a television or any other medium that gives out the sound. In the closed caption method of decoding, media such as television and computer are used. Closed Captionings have both sounds and dialogues in the form of text. Closed Captioning is mainly to help people with hearing problems to understand what's happening on the screen, especially music and sounds they can't hear.
As we said above, SDH means Subtitles for the Deaf and Hard of hearing. Because closed captioning has been traditionally restrictive in terms of colors, fonts, and line length, the movie industry decided to create a special form of subtitling that would uphold the spirit of closed captioning while maintaining a greater degree of stylistic and format flexibility. Subtitles for the Deaf and Hard of Hearing (SDH) will have the same style and formatting options that mainstream foreign language subtitles will have, but they will maintain the speaker identification and sound effects that you would find in a closed captioning file.
