| 摘 要： | 分组网络中丢包对音频流媒体用户体验具有显著影响，为了深入分析两者间的相关性，设计了丢包可控的多媒体仿真传输实验平台，采用回归分析，建立了编码方式、RTP分组间隔等多因素限定下丢包率与体验质量间的映射模型。该模型计算复杂度低，可实时预测丢包对体验质量的损害。

| Abstract: | The Quality of Experience (QoE) of audio stream is significantly affected by packet loss in packet-switch network. To control the loss and analyze its effect on QoE, a simulated multimedia transport test bed was designed. And the mapping model between packet loss rate and QoE was established by regression analysis under specific encoding/decoding mode and Real-time Transport Protocol (RTP) packet interval. The model has low computational complexity and can predicate the impairment of packet loss on user experience in real-time. |

| Keywords: | Quality of Experience audio stream packet loss mapping mode |
