5G-MAG – Reference Tools for 5G Media
Trainer:Daniel SilhavyDaniel SilhavyThis tutorial is a comprehensive deep dive into the world of 5G Media technologies and standards, focusing on the 5G-MAG Reference Tools. The 5G-MAG Reference Tools are aiming to fill the gap between technical specifications for media services and applications and their implementation, conformance testing, validation and prototyping. As part of this tutorial, we dive deeper into the various software packages of the 5G-MAG Reference Tools, specifically addressing the following topics:
- 5G Downlink Media Streaming
- UE data collection, reporting and event exposure
- 5G Broadcast: MBMS and LTE-based 5G Broadcast
- Emergency Alerts over 5G Broadcast
- 5G Multicast and Broadcast Services (5MBS)
- XR Media integration in 5G
- V3C Immersive Platform
