Use Cases

Common Use Case Objectives

The common objectives of the 5GMediaHUB use cases are to demonstrate:

  • how the DevOps testing and validation methodology is used to provide an efficient and effective means for the scheduling, testing, deployment, operation and monitoring of innovative media applications that require 5G performance characteristics;
  • how innovative media applications can be chained to VNFs via relevant NetApps;
  • how NetApps are tailored to the requirements of the media vertical applications;
  • that the underlying 5G NFVI infrastructure, represented by the two 5G testbeds, supports the stringent requirements of the applications in terms of low-latencies and high data rates, evidenced through specific network and service level KPIs;
  • that the 5GMediaHUB Experimentation Facility provides adequate experimentation tools and capabilities to experimenters, including the enablement of the service creation time within minutes.

Use Case 1: Immersive Augmented, Virtual and Extended Reality applications

The objective of this use case is to demonstrate that the 5GMediaHUB Experimentation Facility efficiently supports the execution and operation of immersive technologies, such as Augmented Reality (AR), Virtual Reality (VR), Extended Reality (XR) and interactive IPTV via extensive testing. In addition to the common objectives, the specific test objectives are to deploy such applications through the 5GMediaHUB environment, in order to evaluate the Quality of Experience (QoE) of the immersiveness, interaction capabilities and gamification in new digital media. Two scenarios will be demonstrated in this use case. To realise these scenarios, the applications will be chained to specific NetApps (i.e. ImmersiveMedia, Security and PaaS) and the 5GMediaHUB will demonstrate how the common use case objectives will be achieved.

Scenario 1.1: Immersive 360o VR media experiences:

The scenario to be tested in this use case will be to insert remotely-located teachers into a VR classroom environment to explain a concept to the users, that will feel presence as if they are the students.

Scenario 1.2: Interactive consumption of 8k and VR media content:

This scenario will explore the future of media consumption, which involves UHD 8k and 360º VR media content streamed over 5G, and offering collaborative, interactive experiences. The scenario will leverage a new form of transmedia (i.e. multiscreen) storytelling, termed Interactive Digital Narratives (IDNs), where traditional TV series are enhanced with active participation through interactions and Second Screens, ranging from mobile devices enabled with AR and MR technologies, to VR headsets, allowing for a richer and more engaging user experience.

Use Case 2: Smart media production

The objective of this use case to test the SLA compliance of media vertical applications, and qualify NetApps via the Experimentation Tools of the 5GMediaHUB Facility that include traffic generators and synchronised video stream emulators via pre-recorded content. The effect of MEC nodes and delay jitter will also be measured on how it affects video stream synchronisation in remote production pipelines. Two scenarios will be demonstrated with the overall aim to validate the achievement of the common use case objectives using the StreamSelector, security, PaaS NetApps at MEC nodes:

Scenario 2.1: High quality User Generated Content (UGC) uploading in dense uploading scenarios:

This scenario involves testing a UGC media service scenario in the UGC production domain, highlighting the catalyst nature of 5G networks in advancing significantly the state of the art. The scenario will leverage pre-recorded 4k video content from football matches, as well as multiple 4k UGC streams captured in real time with smartphone applications.

Scenario 2.2: Professional live video production:

This use-case will evaluate “edge-based field production” through the 5GMediaHUB Experimentation Facility to cover for the exponentially growing segment of outdoors production. The application to be demonstrated facilitates local sports events to be recorded and produced in real time by a remote TV production team, that stays physically in the studio.

Use Case 3: Smart media content distribution

The main objective of this use case is to test cross-domain media distribution through the 5GMediaHUB Experimentation Facility, and evaluate how it affects QoS and QoE. To realise the two scenarios, i.e. Dynamic Multi CDN selection for 8k IPTV and Smart City co-creation, the applications will be chained to the MCDN, StreamSelector, Streaming, PaaS and security NetApps to demonstrate how the common use case objectives will be achieved. Furthermore, the MCDN NetApp scalability will be tested in the presence of multiple concurrent IPTV streams. Finally, the CDSO will be evaluated for its capability to ensure cross-domain, reconfigurable slices and NetApps, measuring response time to workload variations.

Scenario 3.1: Dynamic multi-CDN (multi Content Delivery Network) selection for 8k IPTV:

This use-case will deploy the Multi-Content Delivery Network (MCDN) NetApp and will evaluate alternative caching solutions for the transport of UHD IPTV streams.

Scenario 3.2: Smart city co-creation:

This scenario will demonstrate how visual media can be reliably distributed in multiple remote sites or domains, enabling interactive co-creation between citizens and the city. Smart city engagement will be tested through co-creation by citizens usingtheir 5G 4k capable smartphones, co-producing media content, exploring artistic performances and interventions in public spaces.
