Virtual reality (VR) endows any user with a sense of full immersion within a virtual environment. Omnidirectional or spherical video content is the new multimedia format that provides this immersive sensation. The viewer is placed at the centre of the sphere and dynamically changes the displayed portion of the spherical content, viewport.
This new spherical multimedia format and this new interactive way of consuming the content have created novel challenges:
• large volume of data to store, deliver and display,
• ultra-low-delay constraints over bandwidth-limited resources
• uncertainty on the portion of content that will be displayed by the user.
Here, a poster presented by Silvia Rossi during Mildner Memorial Lecture (UCL, 2018), and winner of Cisco Prize.
Invited technical presentation at the 57th FITCE Congress “Delivery and Consumption of Digital Media” (2018), Silvia Rossi presented an overview of her main project, which aims at extending existing video delivery strategies to user-centric ones for spherical contents.
