6G-XR

The Adaptive Video Delivery for Network Music Performance (AViD-NMP) project used the 6G-XR infrastructure to test Network Music Performance (NMP), exploiting the 5G RAN and MEC resources to exchange audio and volumetric video between the participants in XR-enabled NMP sessions. NMP can be a great showcase for 6G-XR: its ultra-low latency and ultra-high bandwidth requirements can only be supported by 5G/6G networks and, while the immersive telepresence required for NMP can be revolutionized by XR, its processing needs can only be supported with acceptable latencies by placing them inside the 5G/6G MEC. Finally, multiparty NMP sessions require SFU/MCU functionality to bridge the participants and allow adapting the media streams to prevailing conditions; these must also be placed inside the 5G/6G MEC. AViD-NMP used the 5G RAN for ultra-low communication latency, and the MEC resources for volumetric video processing and bridging. The focus of the project was on assessing the QoS and QoE of NMP sessions over the advanced testbeds of 6G-XR, as well as assessing the feasibility of XR-enabled NMP over the 6G-XR sites. The AViD-NMP project deployed a fully-fledged multiparty XR-enabled NMP setup that can serve as a popular demonstrator of the advances made by the 6G-XR project.
