Megahertz Ltd will showcase a fast response newsgathering outside broadcast (OB) vehicle at IBC 2017.
The featured truck is one of 25+ vehicles that Megahertz has delivered to a major broadcaster to replace its entire news fleet. It supports quick, simple and reliable on-location content acquisition, editing and transmission for live broadcast missions. Journalists using the mobile unit can gather content via small handheld cameras or the stored on-board ENG camera, or source it from other news crews in a mix of file formats. Audio and stills can also be gathered via iPhone or iPad and edited and transferred through the van.
The long wheelbase Mercedes Vito Dualiner with auto transmission can accommodate a driver and a passenger, along with an extra 100kg of broadcast equipment. It enables the reporting teams to carry out live broadcast quality video contributions to a variety of destinations, via satellite connectivity.
On the roof, a VSAT satellite-based IP connection can easily be switched between Ku-band and Ka-band. The truck is also fitted with bonded cellular connectivity via a 3G/4G cellular roof mounted IP connection, offering its own Wi-Fi signal and the option to be powered whilst the vehicle is in motion. Externally mounted combined 2.4Ghz and 5Ghz WAPs, with an effective range of operation from the vehicle, are also available. A COFDM MPEG4 radio link with small mast is present on two London-based iterations of this vehicle, enabling news crews to lift the antenna above the bustle of the street when required.
In addition, the OB truck provides sufficient battery power to run for a minimum period of six hours of editing, plus one hour of live contribution time. The broadcaster was keen that the unit be as environmentally friendly as possible, so by means of smart load shedding by the Megahertz design team, only the equipment needed is powered up in each stage of the newsgathering process acquisition, editing and transmission. The batteries are charged overnight to support a complete days work, using the engine to top up the battery only in extreme circumstances.
Equipment on-board also includes a TAIT TB7100 communications and CTP talkback system, an NTT MVE5000 encoder, a Blackmagic Smart Videohub and a Blackmagic ATEM Television Studio vision mixer, a Cobham MP4 radio camera system, Sony headphones and Myers microphones.
For business reasons, the broadcaster wanted to use leased vans for the fleet which meant that the chassis of the vehicle could not be cut or drilled into.
This ingenious small format newsgathering vehicle is a credit to the capable and imaginative design and installation teams at Megahertz, especially considering the restrictions associated with a leased vehicle commented Steve Burgess, CTO of Megahertz.
After five years, the van will be returned to the lease company, and the equipment will be transferred to a new vehicle.
We are looking forward to showcasing the van on our stand at IBC 2017 to illustrate how we can tackle even the most difficult system design challenges, concludes Burgess.
