Vision meets culture: XIMEA enables LoLa system with low latency remote visual stream

 

Not just Machine Vision Applications - How imaging powers Classical Concerts Around the World

Musical performances and masterclasses require frequent rehearsal and intense preparation between many individuals, more often than not highly skilled professionals, who live and work in different physical locations around the globe. 

Similar challenges are present in the harmonizing of students with high level valuable teachers and performers which is also true for all other performing arts activities. Bringing all these various people together is time- and cost-intensive.
 

To solve this via remote collaboration a special low latency, high quality audio/video transmission system was developed. It is called LoLa and is specifically designed for network musical performances and interaction. 

This system utilizes the exceptionally low latency of XIMEA cameras to provide »LoLa« with visual stream and empower musicians to cooperate and work together seamlessly in realtime across the globe.

LoLa was developed through a joint effort from Conservatory of Music »Giuseppe Tartini«, Trieste, Italy and »GARR« - Italian Research and Academic Network.

LoLa gives musicians and artists the instruments needed to engage in complex MasterClasses, education activities or to perform rehearsals before physical meetings.

Moreover, LoLa is so far the only audio and video streaming system recognized and adopted worldwide which allows, thanks to its very low latency, the complete remote interaction including musicians playing together in real concerts while still being in different locations. 

Since 2017 LoLa is enhanced by XIMEA USB3 cameras. 

 

On Thursday, February 21st 2019, in the "Tartini Hall" the Conservatory of Music »G. Tartini« in Trieste recorded a musical performance executed with LoLa:

The performance includes the Sonata for violin and piano n. 5 in F major, op. 24 ("The Spring") by Ludwig van Beethoven (1770 - 1827), interpreted by the violinist Qerimaj Kloudennas (Conservatorio Tartini di Trieste) and by the pianist Natalija Mladenović (Belgrade University of the Arts).

Qerimaj Kloudennas performed the solo part remotely from the Tartini Hall of the Conservatory of Trieste, while Natalija Mladenović played in the Great Concert hall of the Faculty of Music of the University of Arts in Belgrade, Serbia.

After the performance of the violin sonata, the students of the Department of Ethnomusicology Belgrade had a 20-minute Serbian folk dances and songs program.

 

A complete recording of the event can be seen here: The performance starts at 2:40, the music at 10:20 

 

 

Since 2017 XIMEA and LoLa have an official partnership.

According to the LoLa project, "XIMEA USB3 video cameras have proven in the field to be the technically best, cost effective and more reliable video hardware compatible with LoLa. With this partnership, we will be able to further improve technical camera features needed by LoLa users, provide better support and offer custom interfaces. Sharing common research will also allow new vision features to enhance the overall LoLa experience even more."

 

Stefano Bonetti from Tartini added: "Using XIMEA cameras is straightforward and simple thanks to the really well written and reliable API / SDK. 

Beyond the excellent quality of the cameras, what surprises me is the great ease of use and immediacy in terms of software development, as well as the remarkable stability, speed and low latency of provided API."
