MagicStream: Bandwidth-Conserving Immersive Telepresence via Semantic Communication

Immersive telepresence, a primary use case envisioned for 6G [1], holds the promise of revolutionizing remote communication by providing deeply engaging and interactive user experiences [2]. Immersive content that depicts 3D objects/scenes is typically represented by point clouds or meshes, allowing users to not only change view directions but also move freely in 3D space, known as six degrees of freedom (6DoF) motion. This capability has driven the adoption of immersive content across various domains, including healthcare, education, professional training, scientific data visualization, and entertainment [3].
