Abstract

The proliferation of Extended Reality (XR) applications, requiring high-quality, low-latency media streaming, has driven the demand for efficient remote rendering solutions. This paper focuses on holographic conferencing in virtual environments and their required uplink and downlink media transmission capabilities. By examining Media over QUIC (MoQ), Real-time Transport Protocol (RTP) over QUIC (RoQ), and Web Real-Time Communication (WebRTC), we assess their latency performance over Wi-Fi and 5G networks. Improvements of approximately 30% in latency and 60% in connection startup are expected in QUIC-based protocols compared to WebRTC. The experimental setup transmits a remote-rendered virtual experience using real-time video streaming protocols to provide the content to the participant. Our findings contribute to understanding the maturity of streaming protocols, particularly within open-source frameworks, and evaluate their suitability in supporting latency-sensitive XR applications. The study highlights specific protocol advantages across varied remote rendering scenarios, informing the design of future XR communication solutions.
