L iveU, Ericsson and Nokia have joined forces to test live video with single and tethered modems. These were transmitted via 5G slices, which were automatically and dynamically adjusted according to real-time analysis.

The three companies worked alongside the University of Patras (UoP) in the framework of the Horizon Europe 5G-Solution project. During the experiment, video was transmitted over 5G slices, which were automatically adjusted based on real-time analysis using LiveU multi-camera LU800 field units and a network management process called Zero-Touch-Automation (ZTA).

Each unit transmitted up to four independent camera data simultaneously by connecting multiple modems, networks or slices. One was a slice set specifically for uplink video contributions from broadcasters, the companies said. The ZTA mechanism is dynamically allocated in real-time 5G slices according to the transmission needs of LiveU units and the total load of the network.

The Ericsson-designed ZTA mechanism identified real-time changes in network performance due to increased charging demand. He then notified the network operator (CDSO, Nokia) who reconfigured the network by creating a special upload-oriented slice (installed by the UoP).

Baruch Altman, head of 5G technology projects at LiveU, said: “These ground-breaking tests have shown how remote production can benefit from real-time, adaptive 5G/6G end-to-end dedicated slot allocation at the highest possible quality. Currently, only cutting-edge solutions such as LiveU's field units can optimally utilize such advanced 5G capabilities and turn them into immediate value for customers while supporting network operators' need for efficient operations. This collaborative achievement once again underscores LiveU's leadership in the development of 5G technology for broadcast, sports, government and other customers.”

The modems of the LiveU units automatically identified the newly available special slot, started using it, and the LiveU bonding algorithms started transmitting live video packets using this dedicated slot. Connecting this slice to "best-effort" slices or commercial networks allowed each LU800 to transmit four video streams simultaneously and in high quality with stable bandwidth and latency, the companies added. The real-time interconnection of special slices with other modems, networks and bandwidths played a significant role in maintaining video continuity and overall QoS, as well as reducing the spectrum required from a new slice.
