Broadcast Systems: Latest OB truck hits the streets of LondonThursday, June 25, 2015 12:00 AM
The latest OB truck built by the WTS broadcast systems integration team has hit the streets of London, taking in the red-carpet glamour of three film premieres in Leicester Square.
The eight-camera rigid HD outside broadcast truck was built by WTS' systems integrators for rental house Video Europe. It is the latest OB facility that WTS has provided for Video Europe, having previously built a 16-camera, double-expanding HD OB truck and tender vehicle, and a full flyaway kit.
The 12-tonne truck – OB5 – is equipped with Sony HDC-2500 camera channels plus two RF camera channels, and two eight-channel EVS XT3 replay systems. It has also already been used to cover Chelsea FC under-21 football matches and Welsh Premier League rugby.
WTS' broadcast systems knowledge key to building new OB truck
WTS' understanding of Video Europe's existing OB systems was an important factor, said Jonathan Lyth, Systems Manager for WTS.
“OB3 needed to match the equipment used across Video Europe’s new fleet of vans and flyaways, using hybrid router technology and a similar design concept to ease the transition between these facilities for engineers and operators,” he explained.
“The build required us to integrate a relatively small vehicle with the level of equipment you’d usually find in a larger OB, whilst maintaining the flexibility of design Video Europe wanted.
“The fact that WTS was able to provide all the requisite services in-house – coach-build, electrical engineering, systems integration and equipment supply – was also a key factor in meeting the quick turnaround Video Europe wanted on the vehicle.”
OB truck offers full range of outside broadcast equipment in a small footprint ideal for London
Built on a DAF LF210 chassis, the vehicle has been specifically designed around the small footprint required for central London productions.
Despite its comparatively small size, OB5 offers a full array of equipment and is capable of handling complex production requirements.
The vehicle boasts a core based around a Grass Valley NVISION 8500 Series Hybrid router with internal frame synchronising and audio manipulation paths, as well as Grass Valley audio and video glue and Trilogy SPGs.
It also incorporates a Sony MVS-3000A 2ME 32-input vision mixer, and can accommodate up to six HD decks or recorders and two eight-channel EVS.
Highly flexible audio configuration in a compact system
Audio is covered by a DIGICo SD9B 48-input audio mixer with Cat6-based stage boxes and a Snell P125 36x36 audio router. Both are connected via MADI to the NV8500 Hybrid router. This provides 32 SDI embedding paths and 16 de-embedding paths, all of which can be passed back to the router, mixer and external MADI streams. The configuration affords great flexibility for such a compact system.
OB5 offers a Telex Zeus 32x32 communications system and a custom camera talkback system to expand the compact frames capability.
Sony HDCU-2500 CCUs are included for use with the eight HDC-2500 camera channels, along with two RF camera channels. Grass Valley was chosen for the truck’s multi-viewers, while the inclusion of an LGZ-USB recorder allows for real-time recording of content to eight USB drives for immediate distribution to stake-holders at the end of a broadcast.
OB truck is part of ongoing expansion of outside broadcast services
The 12-tonne truck is part of the rental company’s on-going expansion and update of its OB fleet.
“Our OB department has gone from strength to strength, particularly since we added OB3, our flagship 16-camera truck, to our fleet in May last year,” said Steve Green, Managing Director of Video Europe.
“OB5 was commissioned to evolve our existing vehicle range and adds another great option to our line-up for our sports and light entertainment clients, as well as for other OB clients.”
Ben Murphy, Sales Director of WTS, said: “We are proud to have played a key role in this exciting expansion of Video Europe’s OB facilities. WTS has now delivered several market-leading OB solutions built to the highest specifications to Video Europe, in the shape of a 16-camera, double-expanding HD truck and tender vehicle, a full flyaway kit and now this eight-camera HD vehicle.”
