Abstract
Systems and methods for negotiating control of a shared audio or visual resource are disclosed. A request for control of a shared audio or visual resource is received at an arbiter. The arbiter maintains existing state information for ownership of the shared audio or visual resource and ownership transition conditions of the shared audio or visual resource. The request is received from one of a process executing on an embedded system and a process executing on a mobile computing device. New state information regarding ownership of the shared audio or visual resource is determined based at least in part on the request for control and the ownership transition conditions. The new state information indicates which of the processes controls output of the shared audio or visual resource.
