Listen to organ interplay between Prague, Czech Republic and Trondheim, Norway

Prague, 13 June 2016. The TNC16 Conference, the year’s largest European networking technology event, has been held in Prague since yesterday. It is attended by nearly 700 experts from 63 countries. Held in Prague’s Clarion Congress Hotel, the event is organized by GÉANT, a European association of national research and education networks. The 32nd annual TNC, whose theme is Building the Internet of People, is hosted by CESNET, the association operating Czech research and education e-infrastructure.

Delegates will discuss current topics concerning research and education networks such as future education models, modern networking infrastructure, research network federation or the related middleware.

However, the hosts have also kept the general public in mind. CESNET, in collaboration with its partners, will organize a unique distributed concert for two remote organs on Wednesday, 15 June, from 3.15 pm to 3.45 pm. It can also be watched on the internet. While Jaroslav Tůma, a leading Czech organist, will play in the Church of the Assumption of the Virgin Mary in Brno, his colleague Jon M. Skogstad will play in a concert hall at the Faculty of Music of the Norwegian University of Science and Technology in Trondheim.

The two organists will have bi-directional audio and video interconnection and their performance will thus be a true musical interplay in real time. The sound of the two organs, together with video, will be transmitted to the large hall of the Clarion Congress Hotel for the final ceremony of TNC 16. However, the concert can also be watched at and will also be streamed over the Internet by Czech Radio in Brno.

The transmission will be via 4K Gateway, a device using technology patented by CESNET. The unique technical solution for video channel synchronization allows for minimum added delay in the order of milliseconds.

The distributed concert will be a typical example of how state-of-the-art, high-speed networks can be used. The event is organized by CESNET in collaboration with the Music and Dance Faculty of the Academy of Performing Arts in Prague, the Norwegian University of Science and Technology in Trondheim, Czech Radio, Norway’s academic network UNINETT and GÉANT.
