摘要
针对无线网络上行带宽有限的情况,提出了无线视频传输带宽的自适应算法。采用双卡发送采集的视频流数据,这样大大增加了无线视频传输带宽。解决了公共无线网络带宽资源有限的问题。使得无线视频传输码率能够达到500～900 kbit/s。在接收端采取双缓冲区的设计,在客户端能够得到清晰、流畅的视频图像。从而解决了无线视频传输和带宽不足的问题。
Because of the limited upstream bandwidth of wire less network, a wireless video transmission bandwidth of the adaptive algorithm is proposed. Use Dual-card send a video stream, so increasing the bandwidth of wireless video transmission. Solve the problem of limited bandwidth resources in public wireless networks. It makes wireless video transmission rate can reach 500 - 900 kbit/s. At the receiving end use double buffer design, the client can get a clear, smooth video images. So solve the bandwidth of wireless video transmission and the problem of bandwidth insufficient.
