Read Abstract +

Immersive video enables end users to experience video in a more natural way interactively with viewer motion from any position and orientation within a supported viewing space. MPEG Immersive Video (MIV) is an upcoming standard being developed to handle the compression and delivery of immersive media content. It extracts only needed information in the form of patches from a collection of cameras capturing the scene and compresses with video codecs such that the scene can be reconstructed at the decoder side from any pose. A MIV bitstream is composed of non-video components carrying view parameters and patch information in addition to multiple video data sub-bitstreams carrying texture and geometry information. In this paper, we describe a simplified MIV carriage method, using an SEI message within a single layer HEVC bitstream, to take advantage of existing video streaming infrastructure, including legacy video servers. The Freeport player is built on the open-source VLC video player, a GPU DirectX implementation of a MIV renderer, and a face tracking tool for viewer motion. A prerecorded demonstration of Freeport player is provided.
