# AVSystemRouting Send media from your app to a TV, speaker, or other device through a media device extension. ## Overview The AVSystemRouting framework lets your app send media to other devices, like TVs and speakers. Media sharing protocol providers distribute media device extensions through their own apps so you don’t need to bundle each device’s SDK in your app. When someone selects a device, your app receives an event describing their choice and starts a playback session on that device.  Your app uses the shared [`AVSystemRouteController`](/documentation/AVSystemRouting/AVSystemRouteController-18ns8) and registers an [`AVSystemRouteControllerObserver`](/documentation/AVSystemRouting/AVSystemRouteControllerObserver-5syvg) to receive routing events. When your app receives an [`AVSystemRouteEvent`](/documentation/AVSystemRouting/AVSystemRouteEvent-2elr5) with an [`AVSystemRouteEvent.Reason.activate`](/documentation/AVSystemRouting/AVSystemRouteEvent-2elr5/Reason-swift.enum/activate) reason, create an [`AVSystemRouteSession`](/documentation/AVSystemRouting/AVSystemRouteSession-gp78) with a URL and an [`AVSystemRoute.LaunchMode`](/documentation/AVSystemRouting/AVSystemRoute-5s2um/LaunchMode) the device supports. The launch mode either plays the URL on the receiver or launches your app’s counterpart there. Add the session to the event’s [`AVSystemRoute`](/documentation/AVSystemRouting/AVSystemRoute-5s2um), then start it; on success, you receive an [`AVSystemRouteMediaSession`](/documentation/AVSystemRouting/AVSystemRouteMediaSession-98ioq) for managing playback. Declare your supported protocols in your app’s Info pane in Xcode using the key, and add as needed for URL-based playback. After starting a session, use the [`AVSystemRouteMediaSession`](/documentation/AVSystemRouting/AVSystemRouteMediaSession-98ioq) class’s playback control to manage remote playback and receive state updates. For communication that includes a companion app on the remote device, use the media session’s data channel and implement [`AVSystemRouteDataDelegate`](/documentation/AVSystemRouting/AVSystemRouteDataDelegate-7vt4b). AVSystemRouting is the app-side counterpart to the framework, which provides the extension API that media sharing protocol providers implement. To learn how extension providers register their protocols and handle playback, see . The two frameworks communicate through the system, so your app never needs to interact with protocol-specific details directly. ## Topics ### Essentials [Routing media to third-party devices](/documentation/AVSystemRouting/routing-media-to-third-party-devices) Respond to routing events and control playback on a TV, speaker, or other media device.
