Abstract

A system and method for streaming media comprises a stream routing processor, a switch controller, a stream caster, media storage, and a packet switch. The stream routing processor determines if the stream caster is configured to stream requested media. The switch controller monitors the status of all devices and events and notifies the stream routing processor if an error or alarm condition occurs. The stream caster streams media upon receiving a valid reservation identification. The media storage stores the media for retrieval by the stream caster. The packet switch transmits signaling and media from the system and between devices of the system, including the stream routing processor, the switch controller, the stream caster, and the media storage.
