WHAT IS STANDARDISATION DOING ON 5G FOR MEDIA?
TAKEAWAYS FOR OPERATORS, SERVICE PROVIDERS AND RESEARCHERS
SUMMARY OF THIS TALK
MORE THAN JUST A FASTER MOBILE NETWORK
WHAT IS 5G?
NETWORK SLICING
WHAT IS 5G?
Network
orchestrator
User habits and expectations with regards to media consumption are profoundly changing: different
types of services, locations of watching and watching devices
Media services have to cope with increasing demands regarding data rates, number of concurrent
users and/or more stringent QoS requirements
5G will integrate seamlessly different network technologies – including unicast, multicast and
broadcast – and capabilities (e.g. caching) which may be needed to provide media services
Scalability of 5G networks will be of critical importance for sustainable business models for
network operators as well as for applications, device and service providers and hence for
continued device and service innovation
5G shall also foster the media innovation ecosystem by opening simple APIs / toolkits /
environments to adapt the network capabilities to content application needs in real time
AN ANALYSIS FROM THE 5G PUBLIC PRIVATE PARTNERSHIP
WHY IS 5G INTERESTING FOR MEDIA?
From https://5g-ppp.eu/wp-content/uploads/2016/02/5G-PPP-White-Paper-on-Media-Entertainment-Vertical-Sector.pdf
automatically programming the behavior of the
network, so that the network smoothly
coordinates with the hardware and the software
elements to further support applications and
services
Separate network services from network
components
automatically configuring the network as per the
service specifications provided
Real time dynamic configuration
NETWORK ORCHESTRATION
MEDIA DELIVERY OVER THE INTERNET USES ABS
The client adapts its requests depending on the bandwidth it experiences (measures)
WELL, THERE IS THE MPEG DASH SAND PROTOCOL…
CAN THE NETWORK AND THE MEDIA CLIENT COORDINATE?
SAND = Server and Network Assisted DASH
DANE = Dash Aware Network Element
Client communicates with DANE using the SAND
protocol on things like: what next chunks its
planning to request, which bitrate should it
request etc.
However: where does DANE take the info to help
the client?
Trust based: how do we ensure that the client
does what it said to DANE?
H2020 EU PROJECT TRIANGLE

LINKING DANE TO NETWORK ORCHESTRATOR
Network assistance
Coordination between media application and network orchestrator
Based on and extending (where needed) 3GPP-SAND and TNO’s innovative SAND-cloud communication protocol
Edge processing
Caching
Transcoding, tiling, filtering, conditioning to better fit the coded content representation to the application’s need
3rd party monitoring / managing APIs
Monitor metrics related to users’ QoE
Request and configure a network slice with specific characteristics
Discover and recommend network assistance channel to media applications
Automated, reproduceable testing framework
Experiment lifecycle automation
Generic component, usable beyond the 5G media vertical testbed
H2020 EU PROJECT 5GINFIRE
CREATING MEDIA SLICES
2 use cases (and 2 slices)
Live media production
Uplink streaming
Video aggregation service: select the stream to send to the broadcaster
Higher quality to selected stream
Low latency VR streaming
Only stream the part of the video the user is currently warching
VR rendering function (tiler) in the network
Extremely low latency

H2020 PROJECT FLAME
USING EGDE COMPUTING FOR LOCALIZED MEDIA PRODUCTION
Edge processing for platform
optimization and user experience
enhancements:
AI curated video feeds with object detection
and categorization
Low-latency live streaming for a local and
real-time experience
Up to 93% bandwidth savings due to local
processing

AS: Application Server (Media) -> streaming server
DN = Data Network
Operators
Find ways to make 5G network attractive to service providers to use:
Provide support services, not application services themselves
Provide APIs and interfaces for service providers to manage their services and slices
Service providers
5G has the potential to offer attractive functionalities to improve services
Need to be more present in standardisation in order to ensure that 5G is set up “open enough” and the right network
services are offered by the operators
Reserarchers
5G has become very complicated – risk that wont be used → focus on simplyfing usage of 5G from verticals
Connect more with industry and standardisation
TAKEAWAYS
What will 5G bring to the future of video?

What will 5G bring to the future of video?

  • 1. LUCIA D’ACUNTO, 24-06-2020 WHAT WILL 5G BRING TO THE FUTURE OF VIDEO?
  • 2. WHAT IS 5G AND WHY IS IT INTERESTING FOR MEDIA? 5G USES NETWORK ORCHESTRATION. HOW DOES IT FIT WITH MEDIA ADAPTATION? HOW DO WE CUSTOMIZE 5G NETWORKS FOR MEDIA? WHAT IS EDGE COMPUTING AND HOW CAN IT BE USED FOR MEDIA? WHAT IS STANDARDISATION DOING ON 5G FOR MEDIA? TAKEAWAYS FOR OPERATORS, SERVICE PROVIDERS AND RESEARCHERS SUMMARY OF THIS TALK
  • 3. MORE THAN JUST A FASTER MOBILE NETWORK WHAT IS 5G?
  • 4. NETWORK SLICING WHAT IS 5G? Network orchestrator
  • 5. User habits and expectations with regards to media consumption are profoundly changing: different types of services, locations of watching and watching devices Media services have to cope with increasing demands regarding data rates, number of concurrent users and/or more stringent QoS requirements 5G will integrate seamlessly different network technologies – including unicast, multicast and broadcast – and capabilities (e.g. caching) which may be needed to provide media services Scalability of 5G networks will be of critical importance for sustainable business models for network operators as well as for applications, device and service providers and hence for continued device and service innovation 5G shall also foster the media innovation ecosystem by opening simple APIs / toolkits / environments to adapt the network capabilities to content application needs in real time AN ANALYSIS FROM THE 5G PUBLIC PRIVATE PARTNERSHIP WHY IS 5G INTERESTING FOR MEDIA? From https://5g-ppp.eu/wp-content/uploads/2016/02/5G-PPP-White-Paper-on-Media-Entertainment-Vertical-Sector.pdf
  • 6. automatically programming the behavior of the network, so that the network smoothly coordinates with the hardware and the software elements to further support applications and services Separate network services from network components automatically configuring the network as per the service specifications provided Real time dynamic configuration NETWORK ORCHESTRATION
  • 7. MEDIA DELIVERY OVER THE INTERNET USES ABS The client adapts its requests depending on the bandwidth it experiences (measures)
  • 8. WELL, THERE IS THE MPEG DASH SAND PROTOCOL… CAN THE NETWORK AND THE MEDIA CLIENT COORDINATE? SAND = Server and Network Assisted DASH DANE = Dash Aware Network Element Client communicates with DANE using the SAND protocol on things like: what next chunks its planning to request, which bitrate should it request etc. However: where does DANE take the info to help the client? Trust based: how do we ensure that the client does what it said to DANE?

  • 19. Operators Find ways to make 5G network attractive to service providers to use: Provide support services, not application services themselves Provide APIs and interfaces for service providers to manage their services and slices Service providers 5G has the potential to offer attractive functionalities to improve services Need to be more present in standardisation in order to ensure that 5G is set up “open enough” and the right network services are offered by the operators Reserarchers 5G has become very complicated – risk that wont be used → focus on simplyfing usage of 5G from verticals Connect more with industry and standardisation TAKEAWAYS
