LiveU, Ericsson, Nokia and the University of Patras demonstrate the benefits of dynamic slicing for video transmission over 5G

LiveU has announced that the company is participating in a 5G demonstration with L.M. Ericsson, Nokia, and the University of Patras (UoP). This development is under the umbrella of Europe 5G-Solution project.

One of the mechanisms of 5G Stand-Alone (SA) networks is “slices”. In essence, this is the ability to provide network space to make a resilient transmission. With this capability, video coverage of events, for instance, has a higher probability of receiving the needed QoS for ultimate signal stability on location.

In this trial, transmitting over 5G slices that were automatically set-up according to real-time analysis was achieved using several LiveU multi-cam LU800 field units and a network management process called Zero-Touch-Automation (ZTA). Each unit transmitted up to four independent camera feeds simultaneously by bonding multiple modems, networks or slices. One of which was a slice specially configured for broadcasters’ uplink video contribution. The ZTA mechanism dynamically allocated in real-time 5G slices according to LiveU units’ transmission needs and the network overall load.

The ZTA mechanism, specially designed by Ericsson, identified in real-time changes in the network performance resulting from the increased upload demand. It then notified the network management orchestrator (CDSO, by Nokia), which drove the reconfiguration of the network (deployed by UoP) by setting-up a special upload-oriented slice. Modems in the LiveU units automatically identified the newly available special slice, started using it, and LiveU bonding algorithms began transmitting live video packets using this dedicated slice.

“These pioneering tests demonstrated how remote production can benefit from real-time, adaptive 5G dedicated slice allocation with the highest QoS possible. LiveU’s field units can make optimal use of such advanced 5G capabilities and convert them to immediate value for the customers, while supporting network operators’ need for efficient operations. This collaborative achievement emphasizes again LiveU’s leadership at the forefront of 5G technology development for its broadcast, sports, government and other customers,” assured Baruch Altman, Head of 5G Technology Projects at LiveU.
