Other broadcasters require BT to have an engineer and truck on site to give a greater level of confidence, and provide additional monitoring at source.”įor big events, such as the IAAF World Championships held at the London Stadium in August, with In this situation, although BT does not have anyone on site, our MCR is able to assist with automated tools and diagnostics that help in problem solving.
“Some broadcasters use the remotely managed service, where they operate on a self-provide basis. It generally provides a mix of services, including HD, UHD, data and internet. Two video monitors display the feed the customer is sending, and BT monitors the cabinets from BT Tower, from where it can also remotely open them for customers. There is also a UPS battery backup that automatically activates during a power failure and will power the cabinets for several hours.

The air-conditioned cabinets are powered by mains power, but there is an option to use a generator (the preferred method during a live event). There is also other equipment that supports the environmental monitoring of the cabinet and network control,” explained Wilson-Dunn. To support the 20 uncompressed HD visions there are no encoders or decoders in the infrastructure, instead we rely upon Nevion IP encapsulation equipment, ADVA optical networking and termination kit, and Cisco switches. “The great advantage of running an uncompressed HD network is that the volume of equipment is significantly reduced. The extra capacity will also further support remote production. In the last month or so it has upgraded to 80Gbps configured as 40+40Gbps, to cope with multiple match camera angles, interview circuits and international broadcaster unilateral material. Initially, the network was for 40Gbps of capacity at each venue – configured as 20+20Gbps giving total diversity between routes to BT’s TVOB Switching Hubs (BT Tower and Colombo House). “Our TVOB network offers flexibility that hasn’t been seen before in the industry, capturing more match-day camera angles and high-quality footage for production houses than ever before,” added Jonathan Wing, Global Sales Director, BT Media & Broadcast. “We believe this volume of simultaneous visions is unrivalled anywhere else in the UK, and possibly in Europe,” he said. “Initially PLP anticipated utilising 10-12 visions per match, but by the second week of the season this had doubled to 24.” The network overall often handles 20+ visions during major matches and has delivered up to 34 signals into and from a single stadium. “Our agreement is to provide PLP with up to 20 linear, uncompressed HD visions, with an additional four visions delivered as either MPEG-4 or J2K ,” said Mark Wilson-Dunn, Vice President of Media & Broadcast, BT. It has also added the national stadiums in England and Wales, and hopes to extend the network where there is consistent customer demand. The tender was won by BT Media & Broadcast, which has developed new fibre cabinets for the project. To cope with this, Premier League Productions (PLP), a partnership between the Premier League and IMG, put out a competitive tender for a fibre-based terrestrial contribution service from all twenty Premier League football grounds to IMG’s operational facility in Stockley Park. Mark Wilson-Dunn: “Our next-generation network is perfectly able to support both main approaches to remote production”
