SRG (Swiss Radio and Television Company) has taken delivery of two of three identical production vehicles from Broadcast Solutions. The three eight-camera OB vans for SRF, RTS and RSI are designed as self-propelled trucks, and are among the first in Europe to have the option of producing audio in Dolby Atmos.

SRG is leading a modernisation project for Swiss broadcasters SRF, RTS, RTR and RSI to replace existing production vehicles that have reached the end of their service life and to have additional UHD-capable vehicles. System integrator Broadcast Solutions carried out the planning and production of the new units, called PaaM (Production as a Module).

SRG relies on a uniform concept and vehicle design for the new mobile production vehicles, enabling SRG and all affiliated broadcasters to benefit from a number of synergies. Procurement is facilitated, and the units’ production costs and purchasing equipment costs are reduced – while the quality of the individual vehicles remains at the highest level. However, the most important advantages of these standardisations are realised in day-to-day production operations.

‘The standardised and identical design of the three vehicles reduces the internal training effort enormously,’ says Tim Rast, who is responsible for the project at SRG. ‘After thorough training, the teams can work easily and quickly on all vehicles and know which technology is located and how the workflows are designed. We are also strengthening internal cohesion and knowledge transfer with this project; the teams can train each other internally, and questions can be discussed and clarified internally in a user group.’

The fact that standardisation does not have to happen at the expense of individuality, and the highest quality is demonstrated by the vehicles both in the basic planning and in the execution. ‘We worked closely with all partners at SRG right from the start so that our specialists, external designers and acousticians could develop the workplace and workflow concept, the acoustics, the interior design and lighting concept together with the customer, and we could respond to SRG’s wishes in the best possible way,’ says Broadcast Solutions Senior Project Manager, Matthias Hahn.

The compactness of the vehicles and the requirements of the SRG result in many individual solutions that Broadcast Solutions implemented in terms of room acoustics, room and workplace concepts, design and lighting design, as well as surfaces and colour schemes.

The vehicles are designed as a truck box-body combination. With a maximum weight of 25 tonnes (max. equipped) and a length of only 11m, they have an extension (over the entire length) and 12 workstations. They can work with eight cameras during productions, in special cases with up to a maximum of ten. The extension and the workstations inside offer full room height, which makes working in this area even more comfortable.

The vehicles’ interior is based on a flexible workstation concept, where several workstations in a second row can be used as needed. From use as an EVS workstation to a desk for editors, many forms are possible. To this end, the work surfaces can be rotated, height-adjusted and moved along the axis and used with or without monitors.

Broadcast Solutions has implemented a sophisticated control with which the user has access to all vehicle systems and parameters to control and monitor the entire technology. The users can control and change the data and status of the hydraulics, air conditioning, power management, lighting installation, and much more via a single module.

At the heart of PaaM is Riedel’s decentralised MediorNet MicroN UHD router. Sixteen MicroN UHD units distribute audio, video and multiviewer signals. The Riedel intercom system uses Artist 1024 and Bolero units. The Swiss broadcasters work in the vehicle with eight Sony HDCU 5500 cameras each. A Sony MVS-7000 vision mixer is used in the control room. Furthermore, two EVS XT VIA servers are installed in the vehicle. The control of the crosspoints, UMD, tallies, and multiviewer signal switching in the PaaM vehicles is handled by the hi human interface control system, an in-house development by Broadcast Solutions, which was individually adapted to the customer’s needs.

The vehicles’ audio – including their ability to worn in Dolby Atmos – is based around a Stagetec Avatus mixing console. Also exceptional is the acoustic concept, which had to cater for the Dolby Atmos mix and is characterised by excellent noise suppression and, in the vehicle, optimal acoustic isolation values. The technical acoustics and sound acoustics leave nothing to be desired, and reflective surfaces were further avoided in the interior.

Broadcast Solutions delivered the first two PaaM vehicles to the customer in 2022, which are already in use. The third PaaM unit will be ddelivered in 2023. Due to the decentralised structure of the Swiss broadcasting landscape, the vehicles’ areas of application are broad and include productions in the areas of sports, events and news.
