System and method for negotiating control of shared audio or visual resource

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. 本发明公开了一种用于协商对共享音频或视觉资源的控制的系统和方法。在仲裁器处接收对共享音频或视觉资源的控制的请求。该仲裁器保持针对共享音频或视觉资源的所有权的现有状态信息和共享音频或视觉资源的所有权转换条件。从在嵌入式系统上执行的进程和在移动计算设备上执行的进程中的一者中接收请求。至少部分地基于对控制的请求和所有权转换条件来确定与共享音频或视觉资源的所有权有关的新的状态信息。该新的状态信息指示进程中的哪一个进程控制共享音频或视觉资源的输出。
