A member of the ATM Group, ATM System is one of the Poland’s leading TV production companies, operating an extensive fleet of OB vans and broadcast equipment. The company recently commissioned a new UHD 4K OB van with 4Vision – having enjoyed a long-term relationship with the broadcaster – handling its construction.
Having built an OB van for ATM some years ago, 4Vision acted as consultants, on issues ranging from coach-building, through equipment proposal, interior and technical design, to cabling and set-up. The OB has been built around 16 Sony HDC-4300 4K/HD cameras, and two LMP Cerberus 4000 miniature cameras, and is equipped to take an additional four wireless cameras.
A BroaMan system, powered by Optocore, has been specified to send video and audio signals to and from the field, for use by journalists and technicians backstage. Local units include two BroaMan Repeat48 optical converters for video I/O, Route66 as fibre router, with TX and RX, and Optocore M8-OPT optical Madi switch for audio connectivity to the Lawo M56 mixing console via a GVG Sirius router.
In each of two video stageboxes there is a BroaMan Mux22-IVT/IVT multi-signal transport device and Optocore X6R-TP-8MI/8LO converter. This feeds programme audio to backstage for use with loudspeakers and/or commentary systems. It can also be used as backup for the audio stageboxes, if more I/O is required, or needed for other locations. In the future, mic inputs will be controllable directly from the Lawo console via the Optocore/Lawo Special Mode).
The Route66 not only transports the signal between local SDI I/O from the Repeat48 and stageboxes: ‘We also use LAN, two in each stagebox patch panel, for example with the Lawo VSM control panels,’ 4Vision Project Manager, Pawel Fila points out. ‘Each stagebox is also ready to connect their EVS control unit via RS422, and ‘dark fibre’ networks using the aux connection. And so it handles nearly everything.’
BroaMan provided full installation support to 4Vision, from system design to training. The new van will now be assigned to general duties, not only in Poland but beyond. Fila confirms that the installation meets the client’s remit in full, and the BroaMan and Optocore devices are functioning flawlessly.
