LiveU participates in a dynamic segmentation trial on 5G

En una experiencia pionera, LiveU, L.M. Ericsson, Nokia y la Universidad de Patras han unido sus fuerzas para probar vídeo en directo utilizando módems individuales y enlazados transmitiendo través de ‘slices’ 5G que se configuraron automática y dinámicamente en función de análisis en tiempo real.

Uno de los mecanismos más prometedores de las redes 5G Stand-Alone (SA) are the slices. En esencia, se trata de la capacidad de proporcionar el máximo rendimiento posible, o QoS, a los usuarios autorizados, de extremo a extremo dentro de la red de radio y núcleo celular.

Esto significa que las aplicaciones centradas en QoS, such as uplink live video streaming for event coverage, from news to sports and beyond, have a higher probability of receiving the QoS necessary for maximum on-site signal stability.

But how can these segments be allocated and managed, and how can the 5G cellular operator provide the level of QoS it guarantees to multiple broadcasters over a specific segment in a given location?

Baruch Altman, head of 5G technology projects at LiveU, confirms that “one of the technical obstacles to the widespread deployment of slices is the static/fixed allocation of resources (spectrum, QoS within network boundaries) and dynamic and on-demand management of slice allocation. This has not been automated yet. “Hence, the theoretical advantages of 5G for remote production at scale have not been fully realized until now.”

In this test, transmission through slices 5G automatically configured based on real-time analysis was achieved using several field units LU800 LiveU multi-camera and a network management process called Zero-Touch-Automation (ZTA).

Each unit simultaneously transmitted up to four independent camera images by connecting multiple modems, networks or slices. One of them was a slice specially configured for broadcasters' uplink video contribution. The ZTA mechanism dynamically allocated 5G outages in real time based on the transmission needs of the LiveU units and the overall network load.

He ZTA mechanism, especialmente diseñado por Ericsson, identificó en tiempo real los cambios en el rendimiento de la red derivados del aumento de la demanda de carga. A continuación, lo notificó al orquestador de gestión de red (CDSO, de Nokia), que impulsó la reconfiguración de la red (desplegada por UoP) mediante la creación de una porción especial orientada a la carga.

Los módems de las unidades LiveU identificaron automáticamente el nuevo segmento especial disponible, comenzaron a utilizarlo y los algoritmos de enlace de LiveU empezaron a transmitir paquetes de vídeo en directo utilizando este segmento dedicado. La vinculación de este segmento con los segmentos best-effort or commercial networks allowed each of the LU800 to transmit four video streams simultaneously and with high quality, with stable bandwidth and latency. The linking of slices special, in real time, with other modems, networks and bandwidths was decisive to maintain the continuity of the video and the general quality of service at all times and to reduce the necessary spectrum of the new slice.

This trial further demonstrated that, even with the ZTA adaptive allocation slice With a dedicated “guaranteed performance” technology, multiple modems, networks and slices need to be linked transparently and agnostically so that broadcasters can enjoy the highest level of video quality and reliability in these congested areas, under changing conditions and over any network configuration.

Altman notes, "These pioneering tests demonstrated how remote production can benefit from end-to-end adaptive 5G/6G dedicated slice allocation in real-time with the highest possible quality of service. Today, only cutting-edge solutions like LiveU field units can make optimal use of these advanced 5G capabilities and translate them into immediate value for customers, while supporting network operators' need for efficient operations."
