The document discusses the potential for 5G and broadcast technologies to work together. It provides background on past attempts at broadcast to handhelds that failed and lessons learned. 5G technologies like FeMBMS/enTV broadcast mode and network slicing could enable improved broadcast to mobile/indoor receivers. The DVB is analyzing scenarios for using 5G networks to distribute DVB services or enhance DVB services with 5G capabilities. Ongoing work includes defining collaboration between DVB providers and 5G operators.

2. Motivation for Broadcast and 5G

3. “The European Union is keen to
make sure the region remains
competitive in a market it believes
could be worth €20bn (£13.5bn) by
2011.”
(BBC News 18 July 2007)
High expectations in broadcast to handhelds

4. • DVB-H
• MediaFLO,
• DVB-SH
• ATSC M/H,
• DVB-NGH,
• ISDB-tmm
• CMMB
Broadcast to handhelds has been tried often

5. • All high power high tower based schemes (including
satellite) have not been successful:
 Commercial challenges, extra costs for handsets, networks
and content and business models did not compensate for
these costs.
 Technical challenges, restricted indoor reception as compared
to mobile outdoor or rooftop.
Lessons learned for broadcast to handhelds

8. Conclusion for broadcast to handhelds
• Handheld indoor reception is a demanding use case.
• Many more transmit sites are required to provide
handheld reception.
• Handheld indoor requires use of a dense cellular
infrastructure.

9. 5G – The new super standard
• High data rates
• Low latency
• Network Slicing
• Virtualisation
• Broadcast mode (FeMBMS)
• V2X (Vehicle to everything)
• .. it will be expensive

10. • eMBMS was specified in Release 11 of 3GPP
• It was not usable for DTT broadcast because of
 small guard intervall (16.7 usec) meaning small SFN cell size
 Only 60% of the carriers within a channel usable for broadcast
• In Release 14 FeMBMS / enTV was specified with improved
broadcast support.
Multimedia Broadcast Multicast Servive (MBMS)

11. • Release 14 provided major changes:
 Dedicated carriers with up to 100% MBMS allocation
 Increased guard intervall for bigger SFN networks (200 usec)
 Receive mode only for devices without SIM or subscription
 Transport-Only (pass through) MBMS bearer type to support e.g.
MPEG2-TS
• First trials with the new FeMBMS are taking place e.g. in
Germany (see Rohde & Schwarz booth in SL)
MBMS: FeMBMS / enTV

12. • Potential Release 16 additions:
 15 km ISD (optimized for higher speeds, e.g. car radio)
 50 km ISD (rooftop reception)
 250 km ISD (TBC)
• With the availability of a powerful, improved FeMBMS there is
no need/interest in 3GPP to develop a specific new broadcast
mode for 5G
• FeMBMS / enTV will be the broadcast mode for 5G
Future 5G broadcast developments

13. 5G discussion in DVB

14. • 5G Study Mission Group (SMG) established
• First step is analyzing scenarios
• Two key scenarios have been identified so far:
• Enable DVB services on 5G connected receivers
• Enhance “DVB Services” using 5G functionalities
• Additional scenarios may be added (e.g. satellite)
• Final report for SB92 (July 2019)
Ongoing Activities

15. • DVB Services over 5G:
• Use 5G Core and RAN for distribution of DVB services
• 5G RAN supports unicast and broadcast modes
• Connected receivers: mobile/tablet, automotive, possibly TVs,
etc.
• DVB-I as standalone service layer for 5G?

17. • Potential enhancements for DVB services:
• VR/XR, interactive, personalized
• Example 3GPP/5G functionalities
• Coverage extension: indoor, outdoor, global
• New device functionalities: Rendering, XR/VR/AI, second screen,
security, location
• Core Network Functionalities: Edge computing, billing,
authentication
Scenario 2: Enhance DVB services and enable new
ones using 3GPP/5G functionalities

19. • Functionalities and services provided by 3GPP/5G can also be relevant
for broadcasters, like e.g. broadcast to handhelds
• DVB has set up a Study Mission Group (SMG) to define DVB's position
towards 3GPP:
 Defining and analyising scenarios of 5G / DVB technology interworking
 Collaboration scenarios between DVB service provider and 5G network
operator
 Cooperation with 3GPP
• Discussions are ongoing and final conclusions have not been
achieved.
• SMG report is expected in July 2019
Summary

20. Conclusion: 5G -the new kid on the block!
