BBC Studioworks upgraded its London Television Centre to support IP, UHD, and HDR workflows using Imagine’s Platinum IP3.
Customer profile
BBC Studioworks Ltd is a commercial subsidiary of the BBC, providing world-class studios and post production services to all the major broadcasters and independent production companies – from the BBC’s EastEnders, Children in Need and Strictly Come Dancing to E4’s Virtually Famous, ITV’s The Chase, ITV2’S Celebrity Juice and Sky’s A League of Their Own. The core of BBC Studioworks’ operations is located across Elstree and Television Centre in White City, London.
Following a comprehensive renovation project, Studioworks in September 2017 re-opened three studios, as well as post production facilities, at the iconic Television Centre, located in London’s White City. For over 50 years, Television Centre was the home to scores of popular British television shows before being sold to property developer Stanhope plc in 2012. The redevelopment project has seen a wide-ranging overhaul of the facility, with Studioworks upgrading everything from dressing rooms and the scenic power and hoists, right through to new ventilation and building management systems. Studioworks has also been refreshing the facility’s technology infrastructure.
While a greenfield technology site eliminates the burden of backward compatibility, it also lengthens and expands the evaluation process due to the need to test and stress a wide-open field of technology options. Given the industry’s ongoing transition from HD to UHD, as well as the increasing prominence of IP for transporting video and audio signals, Studioworks’ technical team was challenged to purchase technology for the three new studios that is optimized to meet today’s demands but also capable of satisfying the video consumption appetites of at least another generation of UK television viewers.
Future support for IP-based production, UHD and HDR was imperative. Television Centre’s storied broadcast history also meant that Studioworks’ refurbished facilities would require meeting exacting quality and reliability standards. A robust and centralized routing architecture, specifically designed for complex and high-demand management of all video and audio signals, was a key requirement. With the wider Television Centre site now a mixed-use building that includes housing units and shops, Studioworks needed to make the most of available square footage by selecting powerful but compact equipment capable of integrating multiple functions and capabilities into a space-saving footprint. The high-volume nature of the studios at the new Television Centre also necessitated new levels of versatility, as each studio would be required to accommodate quick reconfigurations to support a variety of program types, all with different technical nuances and requirements.
The solution
Following an 18-month evaluation period, in which Studioworks technologists kicked the tires of a number of solutions, the company selected Imagine Communications to supply the facility’s core signal routing and management infrastructure. The design of the new Studioworks facility will utilize two Platinum™ IP3 28RU router frames. One will be dedicated to Studio TC1, which will be equipped to provide both HD and UHD production capabilities. The second IP3 will handle signaling for the other two studios, TC2 and TC3, at the refurbished facility.
Both routers support a mixture of copper and fibre connectivity and have interface modules to link to the facility-wide MADI audio infrastructure.
The Platinum IP3 router’s built-in versatility was a major consideration in Studioworks’ selection. In addition to its core signal distribution functionality, the Platinum IP3 supports audio multiplexing and de-multiplexing, flexible and integrated multiviewing, and discrete AES or MADI signals.
The functionality of the Platinum IP3 is designed to be forward-looking and futureproof. It is anticipated that the router’s support for hybrid SDI-IP workflows will provide the company with a smooth and seamless transition path from HD to UHD, HDR and, eventually, higher resolution formats – as well as put Studioworks on the path to all-IP operations. The Platinum IP3 is controlled by Imagine Communications’ Magellan™ SDN Orchestrator (SDNO), a softwarebased control system that supports transparent operations across the two signal formats by providing seamless and synchronous switching between SDI and IP domains. Magellan SDNO is also capable of supporting third-party solutions, providing a single control system for multivendor environments.
Looking forward, the Platinum IP3 also presents Studioworks with a variety of options for supporting IP-based workflows. The Platinum IP3 can be fortified with IP input and output modules based on the AIMS (Alliance for IP Media Solutions) roadmap to seamlessly connect to IP networks built using commercial off-the-shelf (COTS) ethernet switches. In terms of accommodating Studioworks’ eclectic production requirements, the Platinum IP3 is able to save and instantly retrieve a variety of production configurations. The router’s quick-change capabilities help the production house reduce the amount of time it takes to prepare each studio for new production requirements.
tpc now has a future-proof OB truck that will remain on the cutting edge of mobile production for many years to come. The flexible IP architecture is agnostic to video formats and resolutions and able to seamlessly integrate the latest compression schemes and picture-quality enhancements.
The SMPTE ST 2110 specification enables tpc to break out video, audio and auxiliary data into separate, discrete streams — boosting efficiency and flexibility over SDI-based solutions. In addition, the pure-IP approach lessens the cabling and power consumption requirements of an SDI or hybrid SDI-IP environment.
UHD1 is IP at its core and optimized for UHD — using standard or high dynamic range — but is also still capable of handling SDI-based signals. By working with uncompressed and standards-based UHD signals, tpc is able to process video signals to meet all client preferences without requiring a mezzanine compression scheme, while at the same time maximizing video quality and minimizing latency.
Most importantly, the tpc crew was able to get up to speed quickly with the next-generation technology, as it delivers the same performance characteristics and operational look and feel as a traditional SDI system, but with all the benefits of IP connectivity and software flexibility.
“From our technology reviews, we felt that the Platinum IP3 gave us important benefits in system design. The hybrid routing functionality eliminates the need for a separate audio matrix, and the I/O processing capabilities simplify the system architecture and increases flexibility. And the router’s integrated multiviewer also simplifies overall system architecture.”
