A good example of Tv-in-a-box-on-wheels, by Professional Show

A complete TV, Mobile, on three axes with drive on six wheels, designed to operate in extreme weather conditions. Here is the new Ob-Van that Italian company "Professional Show" - in tandem with the team of "One" - has conceived, designed and implemented for the state television of Chad.

The mobile unit has to perform the function of a complete and totally independent TV transmitting station, is to be able to operate in extreme situations, typical of the African continent, and then also must be able to perform anything, from shooting to post-production, the broadcast of programs, including functions as warehouse and all studio shooting.

Thanks to the new Ob-Van, it is possible to produce TV programs and send av contributions to the central control room, and then the broadcasting network, rather than spreading feeds directly via satellite, where everything is self-produced on-board, and complete.
The Ob-Van has two tv cameras on board (expandable to four) with triax connections to the video mixer, 4 wireless tv cameras, as well as three remote cameras, in the studio installed inside the vehicle.
The control room houses the various technical equipments integrated into the system.
The vehicle, of about 10m, also provides an internal shooting studio, in addition to audio and video control rooms and technical area.
The vehicle is a Mercedes Actros 3340 selected as all-wheel drive, capable to walk the streets with a slope of up to 45%, while the construction of the carriages has been carried out by Tomassini Style. In the design, two asymmetric expansions were conceived in order to have enough room to increase the space when the vehicle is in operation. This allows you to host, in addition to the tech and the control rooms, also the shooting area. Also, thanks to the accurate sizing of the work areas, it was possible to host at the back a warehouse where to drop cameras, tripods, wireless transmitters and everything else needed to operate. This is something for which, usually, a separate dedicated vehicle in support is provided. A partial lowering of the roof made it possible to install a satellite dish of 1.80 cm and the headend of the sat up-link. Despite all these equipment on board, inside, the spaces are still livable and comfortable.
The tv cameras are the Grass Valley's LDK8000. Two have been provided with triax connection and the possibility to add two more in the future. But the novelty, for a vehicle of this type, relates to the presence of 4 wireless cameras, always LDK8000, against the common trend as it is usual to have one or two wireless cameras and 4-6 cable connected.
For the lenses were chosen two Canon HJ14EX4.3 three and a Canon Canon HJ17EX7.6BIASE HJ22EX7.6BIASE . Instead, as stands, the choice fell
on Sachtler Dolly with System18.
For the video mixer, here is the Grass Valley Kayak HD100 and for audio the Yamaha DM1000. Obviously, these two products were also chosen for their potential and flexibility, related to extremely compact size. Continuing in the study are three remotely operated Panasonic AWHE120 cameras. For the matrix, the choice has focused on Evertz 5601MSC, combined with the change-over, which is configured on 64X64 3G HD and 32X32 AES for audio. For graphics and post production the choice fall on Avid with Motion Graphics, and Media Composer Nitris DX. There are also two servers Grass Valley K2 Dyno, dedicated to storage, with a MAM software and slow-motion play-out, to realize the simple playlist necessary to the airing of programs, as required by the customer, straight from the OB -Van itself.
For monitoring, the choice fell on Marshall and Black Magic. Tally and audio monitors are marked TSL. The satellite uplink was instead designed and edited by Diem Technologies and provides for the AVL antenna with 180 cm, AVP3000 encoder and decoder of the Ericsson RX8200.
