Singapore (March 29, 2017)—A VSM Broadcast Control and Monitoring System from Lawo provides campus-wide control of the operational infrastructure at Singapore-based broadcaster Mediacorp’s new Mediapolis facility.
Mediacorp’s massive complex houses all production facilities for the broadcaster’s seven television and 12 radio channels. The facility’s two redundant Miranda routers handle switching of audio and video. These are connected directly, and switch simultaneously without any master or backup hierarchy, operating on a master/master basis.
The VSM system ensures the essential synchronization of the two routers. Maintenance of one router can be carried out offline without interfering the production schedule and each router acts as “backup” routers for the other in the event of failure.
The Mediapolis studio complex is divided into four sections: Central, Radio, TV and News. The Central section is further subdivided in three areas: CMX (Ingest), DC (Distribution/Contribution) and Playout. The Distribution/Contribution section uses VSM’s Virtual Package Workflow to allow an incoming source, from OBs or downlinks, to become a virtual source available throughout the facility. If one device in the signal chain fails, the virtual signal is uninterrupted, leaving the signal flow intact while the device is switched or changed.
VSM also adds user rights management, making the virtual layers available throughout the facility conditional on the individual rights of the operator configurations. Only qualified staff can access signals, depending on the rights granted to them.
Within the Radio section of the facility, the same redundancy concept is applied via two Lawo Nova 73 audio routers working in parallel. For the 12 (plus two back-up) radio stations, VSM provides the overall control and monitoring system and keeps the crosspoints of the two redundant routers in sync as well as monitoring the transmission chains for silent detect, alarm management, and other functions.
