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.
