| 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. |
