CBC Mobile Productions Evolves With Évolution
In November, CBC Mobile Productions’ latest unit, Évolution, will hit the road carrying brand-new system designs that reduce the mobile-production unit’s distribution and wiring without compromising its flexibility. The result is a 53-ft. HD production truck that can handle any type of broadcast. Traveling as a single HD truck, without a B unit, Évolution caters to CBC Mobile’s most cost-conscious clientele.
Integrated by Diversified Systems, Évolution was designed and its construction managed by CBC broadcast-engineering personnel. At its core are a Grass Valley Kayenne production switcher and a Calrec Sigma with Bluefin audio console. Also on board are Sony HDC-1500R cameras equipped with Canon lenses; six- and four-channel EVS replay servers; a Chyron HyperX3 graphics unit; and an Evertz MVP monitor wall.
The truck features integrated Evertz audio and video routing.
“The Evertz EQX 288×288 video router includes multi-image–processing units that simplify the system configuration and reduce the quantity of distribution devices and wiring required to efficiently operate the truck,” says Dale Smith, director of CBC Mobile Productions.
An Evertz EMR audio router is integrated with the video, embedded audio router, and Calrec audio console.
“This tight integration allows embedded audio sources and those that are processed by the 48×48 discrete AES matrix to be shared with the audio console through MADI streams,” Smith explains. “This design provides a tremendous number of inputs, a simplified workflow, and quick system setup and configuration.”
The design also allows audio-channel mapping with internal embedding and de-embedding functionality. Audio is embedded into all of the monitoring, eliminating a great deal of cabling and providing freedom to route any source to any destination.
“A large number of multiformat conversion and frame-synchronization units at the I/O panels maintain a simplified signal flow throughout the mobile,” Smith adds.
The design of the Évolution unit also provides redundancies for the most critical technical functions, along with some weight savings, allowing the mobile unit to operate without a separate support truck.
“One of our design concepts for this mobile was to facilitate a quick in-and-out venue-style mobile,” Smith explains. “We also wanted to ensure that Évolution had the engineering resources to cover any large-scale arts and entertainment productions.”
Jeff Vella, director of CBC broadcast engineering, and his team managed to deliver the Évolution mobile in just over seven months.
CBC Mobile Productions ensures that CBC/Radio-Canada programs, such as Hockey Night in Canada, have access to mobile-production equipment and also generates revenue for investing in programming by selling excess capacity.
