A VR 360°-Video Encoding Framework with Differentiated Tile Compression Based on Digital-Twin Technology
Andrea Caruso, Giovanni Schembra · 2024
Virtual Reality (VR) technology is experiencing rapid growth across various sectors, propelled by advancements in networking and multimedia technologies. The interactive nature inherent in$360^{\circ}$video transmission in VR scenarios results in the need of end-to-end communications links with very low latency and very high transmission bandwidth to deliver contents to users. This places strain on network infrastructure, necessitating additional investments in resource management and orchestration. One of the most important approaches being introduced for this purpose in the last years is the Digital Twin (DT) technology. To this purpose, this paper proposes a$360^{\circ}$video streaming framework with differentiated encoding and introduces a DT-based architecture to manage the behavior of the aforementioned framework. The proposed framework is applied to a use case to present some numerical results and discuss how the obtained performance depends on the user's movements while interacting with the viewed scene, under different network delay scenarios.
