5G broadcast brings the promise of an independent or complementary linear TV experience, which can reuse existing terrestrial broadcast infrastructure to serve HD or 4K live contents to mobile devices, possibly independent of a mobile subscription. Designed in Release-14 and 16 by the Third Generation Partnership Project (3GPP), 5G broadcast, targeting the 5G terrestrial broadcast requirements, has been profiled at the European Telecommunications Standards Institute (ETSI). With the coming enhancements from 3GPP, the UHF spectrum allocated for broadcast system could be directly used for 5G broadcast, making possible a smooth transition in the near future. To benefit fully from this new capability, the design of a service layer is essential, including service discovery procedures and the delivery protocols over IP multicast. The Digital Video Broadcasting (DVB) Project is specifying, under the umbrella term DVB-I, a set of Internet-centric standards to bring the delivery of linear TV over IP networks up to the user experience level for the traditional broadcast. Being access agnostic, DVB-I can be used on any network providing IP connectivity, and will allow offering advanced multi-network services. The delivery of DVB-I service over 5G is now one of the main areas of work at DVB.

DVB multicast ABR (DVB-MABR) specifies how DVB-I services can be delivered over multicast, possibly over an unidirectional network. DVB-MABR reuses directly the ROUTE protocol from ATSC3.0. It is in particular used by the DVB TM-NIP working group for delivery of linear content over satellite and will be leverage as well for 5G-Broadcast. The design of 5G Broadcast permits operating different broadcast service layers, possibly targeted to different regions, ecosystems or regulatory requirements. Combining the specifications and tools from different ecosystems is a major effort. In order to support media service providers, a full ecosystem of tools is now emerging from the converging activities from DVB, 3GPP and cross industry associations. Hence 5G Media Action Group (5G-MAG) is developing a Software Defined Radio client for 5G Broadcast. A joint work with DVB is launched to integrate it with a DVB-I reference client. In parallel, delivery of
linear TV services over 5G Broadcast can already be experimented by making use of LTE-Broadcast, as a subset of 5G broadcast, and leveraging the GPAC open source solution, providing the
DVB-MABR functions. 

In this paper, we will introduce the consolidated work from 3GPP and 5G-MAG to make this vision a reality, in terms of standardization and development of reference tools. We will detail how DVB-I over 5G broadcast can now be experimented with commodity tools and commercial devices. We will also identify the potential synergies with ATSC3.0 A/331 and the possibilities for the Brazil’s TV3.0 project, for which ROUTE/DASH is the transport layer of choice and 5G Broadcast is a candidate for the physical layer.
