The largest media organisation and Government-owned radio and television public broadcasting company in Estonia, ERR, has a longstanding relationship with Lithuania-based TVC Solutions over its mobile units. The most recent project was the construction of OB1, a 12m-long 18-camera van whose audio control relies on point-to-point signal transport over fibre from a pair of the BroaMan Mux22 IVT/IVT devices.
TVC Solutions has been designing and coachbuilding OB vans for more than 20 years, and specialises in specifying the most efficient technological infrastructure for any given application. A key feature of OB-1 is efficient use of internal space – offering five working areas and a total 19 of separate workplaces on a chassis-based vehicle design.
The overall build includes main isolated equipment racks with redundant cooling system; a shading area with four workplaces, a second programme area with three workplaces), a main programme and slow-motion operators’ area with ten workplaces, and an audio room with sound isolation. OB-1 can operate with either one or two expanded sides.
Selected by the customer, the BroaMan Mux22 devices can handle different formats of video and data, which can be combined and transported down a single-duplex fibre-optic cable. It is possible to control and monitor every channel and transceiver in the device in real time remotely using Optocore Control application.
In this instance, the Mux22 implementation has been custom-configured as a point-to-point pair as required to transport multiple signals between any two locations, reflecting the OB van’s regular deployment for sports and news coverage, and other outside broadcast assignments.
This is part of a sophisticated construction that, in addition to the expandable sides, includes a quick-to-deploy fully electric side expansion and self-levelling system that takes less time to deploy than previous versions, as well as power, HVAC, lighting, and control systems – all based on the demands of Estonia’s climatic conditions.
The technical infrastructure comprises broadcast industry standard components, built around 18 Grass Valley LDX 3G cameras and a 48-fader Lawo MC256 Mk3 console.
