Abstract—5GMediaHUB aims at building a platform for development, testing and validation of advanced media applications over 5G by providing novel tools for applications developers in the media industry. To validate the platform, different Use Cases have been proposed. In this paper, the first use case “Immersive AR, VR and XR Applications” and its scenarios are described. The Use Case focuses on the transmission of novel multimedia services and content and how this can be optimized to be transmitted over 5G network infrastructures in a way to enhance relevant immersive features. The focus of the Use Case is on 360 immersive video represented at highest available 8K resolution and interactive immersive media using multiple portable devices.
