The top shelf showcases content in a rich, engaging way while also giving people access to their favorite apps in the Dock and on the Home screen. When you support fullscreen top shelf, people can swipe through multiple fullscreen content views, play trailers and previews, and get more information about your content.
The top shelf is a unique opportunity for your app to highlight new, featured, or useful content and let people jump directly to it. For example, when people select Apple TV in the Dock, full-screen previews immediately begin playing and soon the Dock slides away. As people watch previews for the first show, they can swipe to previews of all other featured shows, pausing to learn more about them or add them to a "watch next" list.
