摘　　要：针对内窥镜视频清晰度高、实时性强的要求,该文设计了一个高清晰视频传输系统。该系统使用H.264压缩编码,通过RTP/RTCP协议传输数据,同时利用3G网络在便携式终端(平板电脑、手机)上实现流媒体播放。实验表明该系统在低带宽、高丢包率、高延时条件下视频修复能力强、稳定性好,达到了实时传输流媒体的目的,具有较高的实用价值。To meet the demands of high definition of video and transmission at real-time during the surgery of endoscope, this paper designs an HD mobile video transmission system. This system uses H.264/AVC to encode the original video data and transports it in the network by RTP/RTCP protocol. Meanwhile, the system implements a stable video transmission in portable terminals （such as tablet PCs, mobile phones） under the 3G mobile network. The test result verifies the strong repair ability and stability under the conditions of low bandwidth, high packet loss rate, and high delay and shows a high practical value.
