Abstract
In one embodiment, two or more programmable multimedia controllers are provided a multimedia system that includes a plurality of audio/video (A/V) devices that source or output digital media streams. Each of the programmable multimedia controllers has at least a processing subsystem and a switch capable of switching the digital media streams. Arbitration is conducted among the programmable multimedia controllers to select one of the programmable multimedia controllers as winning the arbitration. Master status is assigned to the one of the programmable multimedia controllers that won the arbitration. Subordinate status is assigned to at least one other programmable multimedia controller that did not win the arbitration. It is periodically verified whether the programmable multimedia controller assigned master status is operating. In response to the programmable multimedia controller assigned master status having experienced a failure, master status is reassigned to a programmable multimedia controller that was originally assigned subordinate status.
