摘　　要：利用基于控制理论的自适应传输机制,提出一种接收方缓冲区驱动的自适应视频多播系统,实现了在不可预约带宽网络环境中的视频自适应传输。仿真结果验证了方法的有效性,可适用于不同的拥塞控制算法和编码算法,扩展性良好。In this paper, a receiver-buffer-driven system is proposed for adaptive video muhicast. The proposed system adapts an adaptive transmission scheme which is based on control theory. Simulation results validate the effectiveness of the proposed scheme. This system can be used for different congestion control algorithms and source encoding techniques. At the same time, the proposed system realizes adaptive video transmission under various Internet conditions.
