Volumetric Video: the MPEG “Metadata for Immersive Video”

In concert with our efforts to compress and deliver high bandwidth video, InterDigital R&I’s Immersive Lab also demonstrated its innovative work to enhance immersive experiences that meet our interactive media demands.  

Valérie Allié and Julian Fleureau’s demo on MPEG Metadata for Immersive Video outlined both the steps to create volumetric video and the requisite format for its distribution. Unlike flat 2D video experiences, volumetric video is much larger and cannot be streamed over traditional networks. In addition, volumetric video requires the capture of real video through camera rigs, the development of computer-generated content, the creation of a composite film sequence using VFX tools, and the interpolation of a video’s view to create a smooth, unbroken rendering of immersive content from the user’s point of view.

Volumetric video is hailed as the next generation of video content where users can feel the sensations of depth and parallax for more natural and immersive video experiences. As AR, VR, and 3D video become a more mainstream consumer demand, providers will require tools to deliver the metadata necessary to produce a fluid, immersive or mixed reality video experience from the perspective of each viewer. As a result, content providers may face challenges in maintaining high video quality while supporting user viewpoint adaptation and low latency.
