VSM for China’s first 4K OB truck

VSM is the overall control system in China’s first 4K OB van, recently put in to service by Jiangsu Broadcast Corporation (JSBC), one of China’s largest broadcasting and media companies.

L-S-B, together with local partner NDT, implemented VSM into this new mobile production vehicle, a 24 camera, double-side expansion van that works in full 4K and offers up to 29 workplaces. The OB works with 16 HD cameras, four 4K cameras and four wireless cameras. Coach builder ASGB and Sony China Professional Systems Group, together with NDT Group, worked jointly to develop a modern OB van with state of the art 4K technology, said L-S-B.

L-S-B’s VSM is running on two separate servers in master-master configuration, with redundancy. A third additional server is used for monitoring other equipment using L-S-B’s own Ember+ protocol and the vSNMP application.

In this large van VSM has full access to the Evertz Xenon router for crosspoint routing as well as to the Sony MVS 7000X vision mixers for control of Tally, UMD and crosspoints. For the audio section JSBC 4K draws on a Lawo mc266 MKII audio console with Lawo Nova Core and Dallis Frames. VSM talks directly to the Lawo equipment and handles crosspoint routing plus parameter control.
