Use case networked music performance 

As a use case, the idea of realistic joint performances of musicians at remote geographic locations was born. One part of the student band—piano (Victor Ardelean Montelongo) and bass (Hans Koennecke)—was based at the University for Music and Theater Munich (HMTM), the other—drums (Max Dost), guitar (Julian Scarcella), and keyboards (Lukas Blecks)—570 kilometers (354 miles) north in Wedemark, near Hannover, at the Sennheiser headquarters. The playing of the “LIPS Brothers” took place in joint sessions, so-called field tests, which were transmitted via internet. A “virtual window” between the two linked rooms was created, which allows a visually and audibly plausible “look” in almost real-time into the other locations. In addition to the broadcast of video and audio, the lighting at both locations was also continuously adjusted. “The goal was to achieve the most immersive and authentic linking of these two exercise rooms. All participants should always have the same impression,” says Hermann Popp.

Both locations were equipped with the same setup and were connected via Wide-Area-Network with a data transfer rate of 1 Gbps. In both directions, six audio channels and one video stream as well as the lighting control information were transmitted.
