Dynamic resolution switching for live streaming

Hai Wei, Sriram Sethuraman, Xin Xiong, Yixu Chen, Yongjun Wu

A bitstream quality metric lets live streams switch resolutions dynamically to cut bitrate needs by 9 percent while using existing protocols.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The DRS framework with its lightweight bitstream-based VQM, trained to maximize subjective resolution cross-over prediction accuracy, enables dynamic ladder construction that achieves approximately 9% BD-rate reduction while remaining fully compatible with existing streaming protocols for live use.

C2weakest assumption

The bitstream-based VQM trained on Pairwise Comparison datasets will accurately identify resolution cross-over points for unseen live content in real time, and that the resulting dynamic selections will translate to measurable QoE gains without introducing unacceptable latency or protocol incompatibility.

C3one line summary

Presents DRS framework for live streaming with a lightweight bitstream VQM trained on pairwise comparison data to dynamically select optimal resolutions per segment, reporting ~9% BD-rate reduction.
