Cyber Performances Become a Reality

CESNET has provided a long-distance concert between Prague and Kuala Lumpur, which are separated by 9,500 km

Prague, 12 August 2015. Long-distance cultural cyber performances are becoming a reality, thanks in part to the contribution of experts from the Czech Republic. Specialists from the CESNET Association are especially active in this field. Yesterday they technically ensured a joint concert of Czech and Malaysian musicians who during the performance were separated by 9,500 kilometres! The broadcast was carried out as part of the 40th anniversary conference of the APAN Association, which is taking place this week at the University of Malaya in Kuala Lumpur. The Asia Pacific Advanced Network (APAN) is an academic organisation which connects networks for research and education in Asia, Australia and Oceania, and ensures cooperation between all academic organisations in the region.

When broadcasting the show CESNET transmitted the musical performance of duo Štěpán Lohnickij (keyboard) and Stanislav Amcha (drums) over a high-speed fibre-optic network from the SAGElab multimedia laboratory in Prague to Kuala Lumpur where, together with Malaysian keyboard player Sulaiman, they accompanied vocalist Zainurul Aniza Abd Rahman (Tinta Rouge).

For those who were interested the concert could not only be watched live from the congress hall in Kuala Lumpur, but also on the internet on SAGElab’s website sagelab.cesnet.cz, where a recording will later be available.

A specific requirement for the transmission of sound in music-making is a very short delay, even when connecting to locations thousands of kilometres away. The requirement for real-time coordination corresponds to a total audio delay of less than 30 ms. CESNET is devoted to this issue as the coordinator of the unique international project eMusic as part of the pan-European initiative GN3plus.

The SAGElab laboratory is the joint workplace of the CESNET association and the IT and Electrical Engineering Faculties of the Czech Technical University in Prague.
