Abstract

A new metric distortion over latency (DOL) is proposed in this paper to overcome the deficiency of the traditional metric interaction latency in measuring the interactive performance of the modern remote rendering systems, which are enhanced with different latency reduction techniques. The proposed metric is novel in combining both latency and rendering quality into one score for measurement. Our experiments validate that in many scenarios, our new metric can effectively distinguish the performance difference between systems while interaction latency can not. The paper also introduces how DOL can be efficiently calculated at runtime.
