Activities on immersive multimedia

Our activities related to the streaming of 360-degree videos and virtual reality applications include:

  • A proposal based on adaptive streaming to prepare and deliver videos so that what the user watches (viewport) represents most of the stream bit-rate. This proposal has led to publications: 
    • Xavier Corbillon, Alisa Devlic, Jacob Chakareski, and Gwendal Simon. "Viewport-Adaptive Navigable 360-Degree Video Delivery", in Proc. of IEEE ICC, 2017. (PDF)
    • Xavier Corbillon, Alisa Devlic, Jacob Chakareski, and Gwendal Simon. "Optimal 360-Degree Video Representation for Viewport-Adaptive Streaming" (submitted)
  • A dataset of more than 50 users watching five 360-degree videos in real conditions. We measure how they move their heads and we obtain statistical models of user behaviors. Here are details:
    • Xavier Corbillon, Francesca De Simone, Gwendal Simon, and Pascal Frossard. (submitted)
  • A set of software tools to manipulate and prepare videos for viewport-adaptive streaming. The software takes any 360-degree video in input and outputs another 360-degree video, which is mapped into another geometric projections and is tiled with various encoding qualities.
  • Contributions to MPEG standard group, including:
    • Viewport-adaptive signalling in DASH
    • Encoding experiment in OMAF

The team consists of Xavier CORBILLON and Gwendal SIMON. Collaborators include Jacob CHAKARESKI (University of Alabama), Alisa DEVLIC (Huawei), and Pascal FROSSARD (EPFL).
