摘 要: 为了给终端用户提供更好质量的视频,本文提出了一种基于H264/AVC扩展的自适应多路径视频流可伸 缩视频编码算法,通过视频流分发网络(VDN)提供路径的多样性,我们的方法最终适应于各种终端用户,并且通过在多 路径上的可用带宽的变化来适应网络带宽的波动。实验表明该算法更能有效地估计网络拥塞状况、降低视频丢包率和减 少网络延迟,从而更有效地保证视频网络传输质量。 |

Abstract: In order to provide better video terminal user,this paper presents an algorithm of adaptive multipath video scalable video coding,which is based on the H264/AVC extension.Through video distribution network (VDN) provides the path of diversity,by using the method of scalable video coding our method finally adapted to the various terminal users,and adapt the undulate of the network bandwidth through the changes of the available bandwidth on the multipath. |
