    Abstract

    In this paper, we describe the implemented 360° live video streaming architecture and evaluation setup running in the 5G test network (5GTN), which can be considered beneficial for live educational services and providing a fast situation awareness in medical sector. The concentration is on providing more global HTTP adaptive streaming (HAS) architecture using also CDN components rather than having only a point-to-point solution. With this setup, we evaluate the common media application format (CMAF) usage in HAS context in order to have reliable video transmission method for high bitrate 360° video as well as setting the end-to-end (e2e) latency as low as possible. By this, both uplink and downlink direction are investigated by using wired, wireless, or mobile connection. In addition, the experienced e2e latency is measured. The extensive placement of synchronized network measurement indicators from distinct network nodes help to identify the bottlenecks in mobile video delivery path and verify the CMAF-based usefulness in streaming optimization. 5G key performance indicators delay and throughput are the key parameters in 360° live streaming, which can be useful in forming the overall, live view of an educational surgery or even from an accident scene. In such scenarios, mobile networking can be the easiest and often the only option for outputting the important information to relevant users, such as students or doctors.
