摘　　要：传统3G视频传输系统通过针对视频内容编码、打包以及传输控制等方面进行优化,来提高视频传输的质量,但是带宽不足的问题一直没有得到有效的解决。该文利用现有的策略路由、虚拟隧道和多网卡绑定三种成熟的网络技术,提出一种基于带宽聚合技术的3G视频传输系统设计方案,并给出其在TMS320DM3730开发板上的具体实现过程。实验结果表明,该系统能够有效聚合3G带宽、提高实时传输视频质量。Traditional 3G video transmission system improves the quality of video transmission through the optimization of encoding the video stream, packing or transmission control and so on. But the problem of lacking bandwidth has not been solved effectively. Using the existing technology of policy routing, virtual tunnel and bonding multicard, this paper proposes a design scheme of 3G video transmission system based on bandwidth aggregation technology, and gives the implementing process which is realized on the TMS320DM3730 development kit. Experiment results show that the system can aggregate 3G bandwidth effectively and improve the quality of the realtime video transmission.
