查询词典 explicit difference scheme

A better algorithm and corresponding real time implementation scheme are proposed. By methodic arranging the clocks of CPU and AD/DA, the scheme can not only scale the pitch in two octave range effectively, but also process the real time input audio for synchronous scaling output. The experimental results on Windows platform indicate the modest CPU and memory consumption, so as to meet the requirement of real time applications.

Nowadays most of researches on the multicast routing are how to generate multicast tree. In case of multicast tree failure, there need to re-route all of nodes behind the failure point so much as re-build the whole tree, this will deteriorate Quality-of-Service, on the other hand, it is insufferable in some multicast applications. We proposed a Fault-Tolerant multicast scheme to resolve this problem. Our scheme creates backup paths crosswise in the ramose node. It can reduce additional cost greatly and recover the failure of multicast tree rapidly.

现在关于多播路由的研究大多着眼于多播树的生成，一旦多播树出现故障，就需要对故障点以下的所有多播接收节点进行重新路由甚至对整个多播树进行重新构造，这一方面降低了服务质量，另一方面有些多播应用不允许长时间的中断，对此本文提出了一种多播容错方案，采用在分枝节点之间建立备份路径的措施，可以在很大程度上减少额外的代价，能够在最快的时间内恢复多播树的故障，并使得恢复后的多播树形状基本上没有改变。
