SDVoE On Stage at MWC19 Barcelona

MWC (formerly Mobile World Congress) Barcelona is a one-of-a-kind immersive experience that gathered more than 109,000 attendees from 198 countries over 4 days this year to learn about the latest trends and industry goals under the theme of “Intelligent Connectivity” – the term used to describe the combination of high-speed 5G networks, the Internet of Things (IoT), artificial intelligence (AI) and big data.

The main conference area, with a capacity for 1500 people, featured a massive 30 x 6.5 meter LED display with 2.9 pixel pitch, offering an astonishing 22 million pixels (10080 x 2184).


How do you deliver extraordinary visuals and run one of the biggest screens (195 square metres) ever used at an event in Spain for a show as important and high-profile as MWC?

Events agency Apple Tree Communications commissioned Power AV, a leading Spanish rental and AV services company with a solid reputation for expertise in video technology, LED screens, sound and lighting, to supply all the AV equipment for the halls in Pavilion 4.

David Martínez, head of Power AV’s office in Barcelona, said, “Right from the very beginning, we knew that to run the content on a screen wi​th these characteristics we needed input from a specialized partner. We immediately thought of MappScreen in Barcelona, which has a team with significant experience managing large format content for big events.”

“Our added value is the management of large-format contents on media servers, video processors and show control systems,” added Isaac Sancho, MappScreen partner. “There are very few companies here who know how to launch and fill multiple large-scale screens with content, and who have the hardware to do it. This is our strong point.”


When MappScreen agreed to take on the MWC 2019 project, it had just acquired a Christie Spyder X80 video processor through Charmex to manage all the signals going to the screen, including presentations, cameras, show control, and multi-windows. The Spyder, in conjunction with Octopus software, also synchronized the lighting and laser show in the hall that accompanied the images on the screen.

​To manage signal transmission, MappScreen used Christie Terra, based on SDVoE technology.  Christie Terra Transmitter was used to extend audio, video and control signals to deliver uncompressed, zero-frame latency, artifact-free 4K content. Christie Terra Receiver was used to decode the data to displays and other AV devices.

​”I have no problem in confessing that I am in love with Terra,” added Isaac Sancho Ferrer, CEO of MappScreen. “At the beginning we thought that it was simply extending 4K video signals, but then we realized that you can practically launch a whole event with it and that it operates like a separate matrix. It is really powerful and affords incredible versatility when it comes to delivering uncompromised signals. At this specific event we used it to extend various different kinds of signals over one single fiber cable.”
