      摘要: 本文提出一種基于心理學近因效應的自適應流媒體用戶體驗質量(QoE)評估方法。近因效應是指在短期記憶中,越是最近的信息越清晰。與傳統的評估方法不同的是,該文提出的新方法考慮到了碼率變化和用戶體驗習慣,利用分治的思想,將自適應流媒體的QoE評估先簡化為固定碼率分段的評估,然后基于近因效應將其綜合起來。該研究進行了一項人群主觀測試,測試數據證明了近因效應在自適應流媒體觀看過程中的存在性。之后,本文對近因效應進行數學建模,并用該模型把自適應流的固定碼率分段評估得分綜合為整體的QoE得分。經過驗證,新的評估方法將測試樣本的評估得分與主觀測試得分Pearson相關系數提高到0.953,并對碼率變化有很好的敏感性。
