    Area of Science:

    • Computer Science
    • Electrical Engineering
    • Multimedia Systems

    Background:

    • Quality of Experience (QoE) is crucial for network optimization in video streaming.
    • Mobile live broadcasting demands real-time interactivity, unlike video-on-demand.
    • Existing QoE metrics struggle with the dynamic nature of live broadcasting.

    Purpose of the Study:

    • To propose a new QoE evaluation approach for mobile live video broadcasting.
    • To address the limitations of current QoE metrics in dynamic live scenarios.
    • To improve the accuracy of QoE prediction by considering temporal dynamics.

    Main Methods:

    • Developed a Temporal Relational Reasoning guided QoE evaluation (TRR-QoE) approach.
    • Utilized deep neural networks (DNNs) to extract quality-indicative features from video frames.
    • Integrated spatial distortion information with multi-scale temporal relational information for comprehensive analysis.

    Main Results:

    • The TRR-QoE approach demonstrated superior performance compared to existing state-of-the-art metrics.
    • Experiments on benchmark databases validated the effectiveness of the proposed method.
    • The approach accurately captures distortion-aware variations in live video content.

    Conclusions:

    • TRR-QoE offers a more robust and accurate method for QoE evaluation in mobile live broadcasting.
    • Explicitly modeling temporal relationships significantly enhances QoE prediction accuracy.
    • The findings contribute to better network optimization and user experience in live video services.
