Delivering Object-Based Immersive Video Experiences

Immersive video enables interactive natural consumption of visual content by empowering a user to navigate through six degrees of freedom, with motion parallax and wide-angle rotation. Supporting immersive experiences requires content captured by multiple cameras and efficient video coding to meet bandwidth and decoder complexity constraints, while delivering high quality video to end users. The Moving Picture Experts Group (MPEG) is developing an immersive video (MIV) standard to data access and delivery of such content. One of MIV operating modes is an objectbased immersive video coding which enables innovative use cases where the streaming bandwidth can be better allocated to objects of interest and users can personalize the rendered streamed content. In this paper, we describe a software implementation of the object-based solution on top of the MPEG Test Model for Immersive Video (TMIV). We demonstrate how encoding foreground objects can lead to a significant saving in pixel rate and bitrate while still delivering better subjective and objective results compared to the generic MIV operating mode without the object-based solution.
