Abstract (en)

[origin: WO9524705A1] A number of multi-media workstations having network and audio/visual (A/V) software are provided to a master control and a number of user stations, and these multi-media workstations are coupled to a number of A/V sources and each other via a multi-channel A/V network and a digital data network. Each of the multi-media workstations is equipped with a multi-channel analog A/V signal receiver, a digital data network interface, a high performance processor, A/V digitization and rendering circuitry, a high pixel density display, and speakers. The multi-media workstations are further equipped with an operating system having integrated network and A/V services, an A/V command handler module, an audio distribution module, an A/V command control module, and a number of A/V applications. The multi-media workstation provided to the master control station is further equipped with a master A/V control module. Together, these elements cooperate to allow A/V materials to be selectably distributed to the multi-media workstations.
