Call For Submissions

In recent years, we have witnessed phenomenal growth in live video traffic over the Internet, accelerated by the rise of novel video streaming technologies, advancements in networking paradigms, and our ability to generate, process, and display videos on heterogeneous devices. Regarding the existing constraints and limitations in different components on the video delivery path from the origin server to clients, the network plays an essential role in boosting the perceived Quality of Experience (QoE) by clients. The ViSNext workshop aims to bring together researchers and developers working on all aspects of video streaming, in particular network-assisted concepts backed up by experimental evidence. We warmly invite submission of original, previously unpublished papers addressing key issues in this area, but not limited to:

  • Design, analysis, and evaluation of network-assisted multimedia system architectures
  • Optimization of edge, fog, and mobile edge computing for video streaming applications
  • Optimization of caching policies/systems for video streaming applications
  • Network-assisted resource allocation for video streaming
  • Experience and lessons learned by deploying large-scale network-assisted video streaming
  • Internet measurement and modeling for enhancing QoE in video streaming applications
  • Design, analysis, and evaluation of network-assisted Adaptive Bitrate (ABR) streaming
  • Network aspects in video streaming: cloud computing, virtualization techniques, network control, and management, including SDN, NFV, and network programmability
  • Routing and traffic engineering in end-to-end video streaming
  • Topics at the intersection of energy-efficient computing and networking for video streaming
  • Network-assisted techniques for low-latency video streaming
  • Machine learning for improving QoE in video streaming applications
  • Machine learning for traffic engineering and congestion control for video streaming
  • Solutions for improving streaming QoE for high-speed user mobility
  • Analysis, modeling, and experimentation of DASH
  • Big data analytics at the network edge to assess viewer experience of adaptive video
  • Reproducible research in adaptive video streaming: datasets, evaluation methods, benchmarking, standardization efforts, open-source tools
  • Novel use cases and applications in the area of adaptive video streaming
  • Advanced network-based techniques for point clouds, light field, and immersive video
  • Low delay and multipath video communication

Keynote Speech

The workshop keynote speech will be delivered by Prof. Filip De Turck.

Title: Towards Immersive Volumetric Media Delivery

This keynote talk will first present a review of video streaming over telecommunication networks, and its evolution over time. The importance and the opportunities provided by volumetric media delivery will be outlined by means of several examples. The most appropriate platform design for volumetric media delivery and the various challenges and possible approaches will be highlighted next. Finally an overview of research challenges and opportunities will be presented.
