A Scalable Platform for Innovations on Real-time Immersive Telepresence (SPIRIT) open call 2 project
QUIC is a recently standardised general transmission protocol that has many favorable properties for real-time media transmission over the de-facto WebRTC protocol suite, which is used throughout the SPIRIT project. In resource-constrained situations, for example, when there is a sharp bandwidth drop or right after a client migration event, QUIC can provide better quality by omitting the transmission of less relevant data, compared to randomly dropping data packets. Several proposals exist for achieving prioritization by distributing the video in QUIC streams. However, finding the best-performing scheduling strategy for telepresence applications requires further research.
In this project we intend to extend our existing QUIC-based video transmission toolset with multi-streamed video transmission capability; integrate our GStreamer-based sender with the holographic telepresence scenario; study and implement different stream scheduling strategies to improve QoE; extend our existing measurement tool to receive multi-streamed video transmission; conduct measurements in the imec testbed; and disseminate the results.
Execution time frame: April–November 2025
