BLUEPRINTS & ARCHITECTURE

The initial focus of the project has been the development of Rel-16 5G Media use-cases, targeting 5G Media Streaming and 5G Broadcast and including client, server/headend components and corresponding 5G unicast and broadcast radio emulators.

The setup should provide an end-to-end platform enabling the implementation of applications (media players) on top of the clients; service layers and applications developed by other media-related organizations; hybrid scenarios and integration of third-party functions in the network.

Within the initial phase of the project, the following components are expected to be developed:

• General aspects:

  • Provide an architecture for the implementation of the client

  • Identify existing code and remaining tasks to be completed

  • Decide on architectural aspects such as APIs, code language, code re-use.

  • Ingest of reference services using CMAF/DASH/HLS

  • Ensure forward compatibility with potential beyond Rel-16 developments in 3GPP

  • Test Services for 5G Media Streaming and Broadcast server/headend

  • Identify relevant test service and test streams

  • Develop basic tools to develop test services and test streams

  • Provide a hosting environment for test material

  • Identify conformance aspect of test streams

  • 5G unicast and broadcast emulator for simulating core network and RAN

  • Reusing SRS-RAN code as per the original setup by ORS

  • Check who would be interested in developing Release 16 and NR unicast (both SRS-RAN based)

  • Auxiliary processes to use the setup end-to-end (e.g. integrating the receive process from ORS-OBECA, the gateway, application, etc)

• 5G Media Streaming

  • Ensure compliance with TS 26.501/TS26.512 Rel-16

  • 5GMS Client : dash.js + MSH with Md5-8

  • 5GMS AF and AS with Md1-4 + 8

• MBMS / LTE-based 5G Terrestrial Broadcast

  • Ensure compliance with ETSI TS 103720 and the corresponding 3GPP Technical Specifications

  • MBMS client with MBMS-APIs

  • BMSC with xMB
