Summary

This research introduces a novel large-scale subjective dataset for multi-screen video quality assessment (VQA) on mobile devices, collected from over 300 distinct Android devices. The dataset is enriched with comprehensive metadata detailing viewing conditions and display characteristics, which are crucial factors influencing perceived video quality. The study proposes a strategy for extracting aggregated quality scores and adapting VQA models to provide device-specific quality estimations. Experimental results demonstrate that integrating device and contextual information significantly enhances the accuracy and flexibility of quality prediction. This approach offers new avenues for fine-grained optimization within streaming services, ultimately advancing perceptual quality models to better reflect diverse real-world media consumption environments. The dataset and code are publicly available.

Key takeaway

For AI Engineers developing video quality assessment models for mobile streaming, you must integrate device-specific and viewing condition metadata. Relying solely on generic VQA metrics will lead to suboptimal user experiences. Leverage the newly released dataset and proposed adaptation strategy to build more accurate, context-aware models. This enables fine-grained optimization of your streaming services, ensuring perceived quality aligns better with diverse real-world consumption environments.
