A new technical report being presented at IBC 2023 describes how DVB-I can provide a service layer for any IP-based system, including 5G Media Streaming and 5G Broadcast.
It follows the establishment of a joint task force between DVB and 5G-MAG.
The report, TR 103 972 v1.1.1, 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 LTE-Based 5G Broadcast from ETSI JTC Broadcast. It also sets out the 5G-MAG Reference Tools architecture and client.
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.
The Joint Task Force was led by Dolby’s Frédéric Gabin (for the DVB Project) and Qualcomm’s Thomas Stockhammer (for 5G-MAG). The BBC’s Richard Bradbury was also a major contributor to the work.
It began work early in 2022 with a 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 task force is now being wound down and the required follow-up work will continue within the respective organisations.
