Free-viewpoint video streaming challenges

Free-viewpoint video (FVV) streaming systems face several challenges [1]:


  • Responsiveness. Users should be able to interact with the system in real-time. The delay between a request for viewpoint change and the rendering of the target view should be minimized. This includes network-related delays as well as processing delays.
  • Scalability. The system should be able to handle a large number of concurrent clients that are possibly viewing the scene from different angles.
  • Adaptability. The system should provide the best possible quality to heterogeneous clients while handling network dynamics, such as bandwidth variation.
  • Immersiveness. A user should be able to choose between a large number of viewpoints and transition smoothly between them in order to provide a truly immersive experience.
