COP15 hosts summit for Mayors

The AV Center handled the audiovisual system for a massive meeting of Mayors, from leading cities across the globe, held outside the COP15 climate summit. The City Hall in Copenhagen had to host five different podiums where five discussions were held at the same time.

Held from December 14 to 17, the event gathered the most powerful mayors from almost 80 cities all over the world as well as influential politicians and other key actors fighting to protect the environment. Among the figures who attended the summit were Governor Arnold Schwarzenegger, Mayor of New York city Michael Bloomberg and Sir Richard Branson, chairman of Virgin Group.

During four days, cities demonstrated that they are on the frontline of climate change. Politicians shared best practices and discussed about how they could provide new solutions to take up the challenge of climate change.

Mikkel Behrend, rental manager at the AV Center, Copenhagen, said: "The job was to transform the City Hall of Copenhagen into a discussion platform with five different podiums where five discussions were held at the same time.

“A huge wide screen was displaying live pictures from each room. Thanks to interpretation systems, the audience could tune into their preferred room and listen to the live discussion.
To achieve this, we provided the whole AV system including a complete sound, light and video setup with five mobile two-camera productions, mixing equipment, a screen of 81 sqm and the interpretation system."

The company implemented a system consisting of two Analog Way Di-VentiX II, multi layer high resolution mixer seamless switchers and an Analog Way Axion event controller. Furthermore, two Digital Projection HD45 lightening projectors of 30,000 Ansilumens each were used for the show and back up.

A Fiberline connection was used between the switchers and projectors. Sound reinforcement was handled by a Nexo line array speaker / amps system. The company also implemented a 40 channel wireless microphone system.

A complete light setup with LED moving heads and light controls was used. The AV Center also provided a Bosch DCN interpretation system with 500 delegate units and a Bosch DCN transmission system. The AV Center also set up a live video link connection to the “Hopenhagen Area” in front of the City Hall.

Behrend said: “There were a lot of wireless frequencies running at the same time and it was a challenge to handle them."

He continued: "We needed the ability to display five PIPs over a background on the screen. PIPs were showing the discussion being shot live on each podium. To achieve this, we used two units of Analog Way's Di-VentiX II. One unit was used to display three PIPs, and the other unit was handling two PIPs and a background that was sent from a PC. Finally, the devices were handling computer, SDI and HD SDI video formats.

“The products fulfilled the technical challenges and we met our customer's requirements. The Copenhagen City Hall was very happy with the event and the A/V system," Behrend concluded.
