| 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. |
