MultiMoQ accepted at ACM Multimedia
Our paper on "MultiMoQ: Multi-Access Media-Over-QUIC for Robust Immersive Video Streaming" has been accepted for publication at ACM Multimedia 2026.
Abstract
Live immersive video streaming, particularly 360° video, is increasingly adopted in applications such as virtual events, sports broadcasting, and remote education. Existing approaches struggle to support high-bitrate immersive streaming for large numbers of concurrent users, with coarse-grained delivery limiting responsiveness and insufficient support for coordinating concurrent tile streams.
Media over QUIC (MoQ) has recently emerged as a promising solution for large-scale media delivery, yet it lacks robustness under bandwidth-constrained conditions, often resulting in playback stalls. To address these challenges, we present MultiMoQ, a multi-access tile streaming framework built on MoQ that redesigns its delivery mechanism to enable robust high-bitrate streaming across multiple access paths, while supporting flexible tile scheduling and seamless access switching without playback stalls.
We implement a fully functional prototype of MultiMoQ and evaluate it in network emulation under heterogeneous real-world network conditions, comparing against Dynamic Adaptive Streaming over HTTP (DASH) and standard MoQ. Results show that MultiMoQ significantly improves robustness, increasing average goodput by about 61% and reducing tail end-to-end latency by about 69% compared to DASH, while reducing average stall time by about 97%ccompared to standard MoQ. These transport gains also translatecinto smoother viewport playback, reducing playback freeze ratio to 1.09%, compared with 3.96% for standard MoQ and 51.5% for DASH.
