This work presents eight demonstrators and one showcase developed within the 5G-Xcast project. They experimentally demonstrate and validate key technical enablers for the future of media delivery, associated with multicast and broadcast communication capabilities in 5th Generation (5G). In 5G-Xcast, three existing testbeds: IRT in Munich (Germany), 5GIC in Surrey (U.K.), and TUAS in Turku (Finland), have been developed into 5G broadcast and multicast testing networks, which enables us to demonstrate our vision of a converged 5G infrastructure with fixed and mobile accesses and terrestrial broadcast, delivering immersive audio-visual media content. Built upon the improved testing networks, the demonstrators and showcase developed in 5G-Xcast show the impact of the technology developed in the project. Our demonstrations predominantly cover use cases belonging to two verticals: Media & Entertainment and Public Warning, which are future 5G scenarios relevant to multicast and broadcast delivery. In this paper, we present the development of these demonstrators, the showcase, and the testbeds. We also provide key findings from the experiments and demonstrations, which not only validate the technical solutions developed in the project, but also illustrate the potential technical impact of these solutions for broadcasters, content providers, operators, and other industries interested in the future immersive media delivery.

在 5G 广播和组播测试网络上演示沉浸式媒体交付


这项工作展示了 5G-Xcast 项目中开发的八个演示器和一个展示柜。他们通过实验演示并验证了与第五代 (5G) 中的多播和广播通信功能相关的未来媒体交付的关键技术推动因素。在5G-Xcast中，现有的三个测试床：慕尼黑（德国）的IRT、萨里（英国）的5GIC和图尔库（芬兰）的TUAS，已发展成为5G广播和组播测试网络，这使我们能够展示我们的愿景具有固定和移动接入以及地面广播的融合 5G 基础设施，可提供身临其境的视听媒体内容。 5G-Xcast 中开发的演示器和展示基于改进的测试网络，展示了该项目中开发的技术的影响。我们的演示主要涵盖属于两个垂直领域的用例：媒体和娱乐以及公共警告，它们是与多播和广播交付相关的未来 5G 场景。在本文中，我们介绍了这些演示器、展示和测试平台的开发。我们还提供了实验和演示的关键发现，不仅验证了项目中开发的技术解决方案，还说明了这些解决方案对广播公司、内容提供商、运营商和其他对未来沉浸式媒体感兴趣的行业的潜在技术影响送货。
