What will 5G bring to the future of video?

In this talk, I will present the recent advancements on 5G for what concerns support for “the media vertical sector”, i.e., use cases involving the transmission of audiovisual content. I will begin by introducing the research that TNO has conducted on this topic in the past few years, starting with the H2020 TRIANGLE project, were we first adapted network orchestration to “communicate” with media orchestration components, such as a DASH Aware Network Element (DANE). Then, I will explain how we created media-specific 5G slices in the context of the H2020 5GINFIRE project, and what benefits media service providers can expect. I will further discuss about the advantages that edge computing offers to video production, based on our results from the H2020 FLAME project. Finally, I will give an overview of the standardization activities around this topic. I will conclude my talk with an outlook on future developments and offer some reflections on what researchers, telecom operators and service providers can expect.

What will 5G bring to the future of video?

  1. 1. LUCIA D’ACUNTO, 24-06-2020 WHAT WILL 5G BRING TO THE FUTURE OF VIDEO?
  2. 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. 3. MORE THAN JUST A FASTER MOBILE NETWORK WHAT IS 5G?
  4. 4. NETWORK SLICING WHAT IS 5G? Network orchestrator
  5. 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. 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. 7. MEDIA DELIVERY OVER THE INTERNET USES ABS The client adapts its requests depending on the bandwidth it experiences (measures)
  8. 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?

  12. 12. 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
  13. 13. 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 EU PROJECT 5GINFIRE CREATING MEDIA SLICES

  15. 15. H2020 EU PROJECT 5GINFIRE CREATING MEDIA SLICES Rendering function Video aggregation function
  16. 16. Localized crowdsourced live video streaming system A smartphone application and platform for producing and consuming live video content Use of edge computing and AI for platform optimizations and enhancing the user experience Technical and user trial in Bristol using the edge-enabled FLAME network infrastructure H2020 PROJECT FLAME USING EGDE COMPUTING FOR LOCALIZED MEDIA PRODUCTION
  17. 17. 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 H2020 PROJECT FLAME USING EGDE COMPUTING FOR LOCALIZED MEDIA PRODUCTION

  19. 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
