摘要

针对IP网络带宽的有限、时变和“尽力而为”的特性，为了保障视频传输的服务质量（QoS），提出了一种新的GAIMD_Buffer自适应传输方案.该方案在GAIMD算法的基础上增加了服务端和客户端的H-264视频流缓冲控制策略.当网络处于稳定或拥塞状态时，若下一个RTT时刻缓冲区占有量的估计值位于设定的阈值内，则按照GAIMD算法来调整发送速率，否则通过调整视频的编码码率来保证缓冲区不会发生上溢或下溢.实验表明该方案在嵌入式系统中能够更有效地平滑速率抖动，减少数据丢失，降低播放延时，进一步提高视频播放质量.

Abstract

Taking into account that the network bandwidth has limitation

instability and "making the best" service

it proposes a novel adaptive transmission scheme named GAIMD_Buffer to ensure QoS of video transmission. Based on GAIMD algorithm

the scheme introduces a buffer control strategy of H.264 video streaming for both servers and clients. When the network is in a stable or congested state

and the estimated value of the buffer occupancy is within the given threshold in the next RTT as well

the speed of transmission is adjusted by GAIMD algorithm; otherwise

the stability of the buffer can only be ensured by adjusting the video code rate

which ensures the buffer will not overflow or underflow. Experimental results demonstrate that the proposed scheme works well in the embedded system

which shows more effective smooth jitter

less packet loss and play latency

and improves video quality accordingly.
