#CMT# #/CMT# The installation has a control and monitoring signals communication network i.e. logical network (20) and a logical server (21) connected to the network. The server emits control and monitoring signals over the network. Each of interface devices (1-5) has switching modules (22) that ensure the connection of the device to a digital data communication network (10) and to the server in respective states so that the modules receive the signals for emission of the data flow to be transmitted on the network (10). The digital data represents information flow to be transmitted. #CMT#USE : #/CMT# Used for broadcasting sound or visual information flow of concerts, Olympic competitions, film projections and public addressing in a public establishment such as concert hall, conference room, Olympic stadium, airport, station, railway station and industrial site, over a digital network e.g. Ethernet network. #CMT#ADVANTAGE : #/CMT# The installation permits to transport and propagate audio and/or video data in a synchronous manner towards multiple devices while guaranteeing a reliability and service continuity in case of disruption of connection cables or loss of one of the devices. The installation is easy to maintain and can be added with modules during the operation without loss of the signal transmission, while being remotely controlled in an ergonomical manner. The installation permits #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a sound or visual information flow broadcasting installation. 1-5 : Interface devices 10 : Digital data communication network 18, 19 : Transmitters/receivers 20 : Logical network 21 : Logical server 22 : Switching modules. |
