Title: A WebTransport-based System for Cloud Streaming Authors: Minh Nguyen; Dominik Busse; Stefan Pham; Stephan Steglich; Stefan Arbanowski; Leon Holtmeier Venue: Mile-High Video Conference (MHV) Year: 2025 Canonical: doi:10.1145/3715675.3715820 URL: https://doi.org/10.1145/3715675.3715820 Collector: openalex OA: true ABSTRACT In recent years, the demand for remote rendering and cloud gaming solutions has grown significantly, pushing the boundaries of traditional game development and distribution methods. This work aims to explore and implement a novel approach to streaming rendered frames from the Unity game engine to web clients using the WebTransport protocol [4]. Unity, one of the world's leading game development platforms, provides a powerful environment for creating interactive 3D and 2D content. Its versatility and extensive feature set make it an ideal candidate for exploring advanced rendering and streaming techniques. While Unity already offers solutions to enable the direct streaming of rendered content, we aim to incorporate the new web standard "WebTransport" and test the feasibility of using this new method of data transfer. Built on top of HTTP/3 [3], WebTransport provides low-latency, bidirectional, and multiplexed data transfer between clients and servers. Its ability to handle both reliable and unreliable data streams makes it particularly suitable for real-time applications like game streaming.
