A new Technical Report from ETSI, arising out of a collaboration between the DVB Project and 5G-MAG, provides guidelines on the deployment of DVB-I services over 5G Systems including the 5G Media Streaming Architecture and LTE-based 5G Broadcast. Published just ahead of the summer break in Europe, TR 103 972 v1.1.1 shows how relevant components from both the 5G and DVB ecosystems can be smartly combined to address several media service scenarios.
JOINT TASK FORCE SUCCESSFULLY CONCLUDED
The Joint Task Force between DVB and 5G-MAG kicked off early in 2022 with the mission to map the Commercial Requirements for DVB-I service support over 5G networks and systems (DVB BlueBook C100) into a set of deployment guidelines.
The resulting ETSI Technical Report includes high-level summaries of technologies from DVB (DVB-I, codecs, and delivery formats such as DVB-DASH, DVB-MABR and DVB Native IP), from 3GPP (5G System, 5G Media Streaming, eMBMS and enhanced TV), and of the LTE-based 5G Broadcast System defined in ETSI JTC Broadcast.
The report also sets out the 5G-MAG Reference Tools architecture and client components related to DVB-I over 5G.
The detailed service scenarios covered in the report are:
Standalone DVB-I service using 5G Broadcast
DVB-I service using 5G Media Streaming
DVB-I service offering available simultaneously over broadcast and unicast.
A DVB-I over 5G reference architecture is proposed to support all service scenarios and requirements. Each scenario includes workflows with guidance on relevant specifications. Gaps in existing specifications are identified and documented as recommended changes to the relevant specifications under the control of DVB, 3GPP or ETSI.
IBC PAPER
The Joint Task Force was led by Dolby’s Frédéric Gabin (for the DVB Project) and Qualcomm’s Thomas Stockhammer (for 5G-MAG). Richard Bradbury of BBC was also a major contributor to the work. A technical paper on the work by the three will be presented during the IBC2023 conference during a session on 5G technology convergence with broadcast.
More than 65 people from among the memberships of DVB and 5G-MAG joined the Joint Task Force to follow and contribute to the work, representing more than 40 companies in total. With the ETSI report now published, the task force will be wound down and the required follow-up work will continue in the respective organizations.
5G-MAG REFERENCE TOOLS FOR DVB-I OVER 5G UNDERWAY
The 5G-MAG REFERENCE TOOLS; the open-source software development programme established by 5G-MAG and open to the community. is already developing the 5G Systems for multimedia applications, including the 5G Media Streaming Architecture and LTE-based 5G Broadcast. Its extension to support DVB-I services is on the roadmap for the comming months. Contributions are welcome and developers can contact reference-tools@5g-mag.com or explore the Developer Space for more information.
