【摘要】 采用快速传送协议/用户数据报协议/IP方式实现了多模式无线网络(WLAN、GPRS、CDMA)的码流传输,并完成无线通信下的RTCP双向控制信息链路。针对无线IP网络的传输特性,选取了适当的QoS参数反馈控制传输质量。实验测试表明,多模式无线通信系统下的码流传输在接收端取得了较好的视频传输质量。更多还原

【Abstract】 The paper introduces the video transmission by using the protocol of RTP/UDP/IP over Multi-Mode wireless networks(WLAN,GPRS,CDMA) and establishes the RTCP bi-direction control information link under wireless communication.Aiming at the transmission characteristics of wireless IP network,some relative QoS parameters are adopted to control transmission quality.Experiment results show that the video transmission in our system can obtain satisfactory video transmission quality.更多还原
