摘要： 在分析RTP/RTCP 协议特点的基础上，结合面向连接的传输协议TCP 中保证传输数据可靠性的重发机制思想，考虑多媒体实时传输中数据包丢失的因素，设计了选择重发机制算法，使得多媒体实时传输过程中关于数据包丢失影响QoP 的情况得到了改善。

Abstract: Based on the analysis of RTP/RTCP protocol’s characteristics, combined with the design thought of resending mechanism for transmission reliability in the connection-oriented transmission protocol TCP, this paper considers the facts of packets lost in the multimedia real-time transmission, and designs the selective resending algorithm for improving QoP, which is deteriorated due to packets lost in multimedia real-time transmission.
