Abstract

In the paper, we propose the pause-and-run approach for k-stream (PARK) multimedia presentations over the Internet to achieve reliable transmission of continuous media. The main characteristics of the PARK approach are as follows: (i) to achieve reliable transmission of continuous media, PARK adopts TCP instead of UDP; (ii) since the slow-start scheme is embedded in TCP, a novel flow adaptation scheme is proposed to reduce the overhead of the network and end hosts. The server adapts its transmission rates to the buffer situation of the client and prevents the client's buffers from overflow and underflow as much as possible; (iii) with the provision of multiple-stream synchronization and multi-level adaptation control, the client achieves smooth multimedia presentations and achieves graceful presentation degradation when the resources are insufficient.
一个暂停和运行的k流多媒体同步控制方案
在本文中,我们提出了k流(PARK)多媒体演示的暂停-运行方法,以实现连续媒体的可靠传输。PARK方法的主要特点如下:(i)为了实现连续媒体的可靠传输,PARK采用TCP而不是UDP;(ii)由于TCP中嵌入了慢启动方案,提出了一种新的流量适应方案,以减少网络和终端主机的开销。所述服务器根据所述客户端的缓冲区情况调整其传输速率,并尽可能防止所述客户端的缓冲区溢出和下溢;(iii)客户端提供多流同步和多级自适应控制,实现流畅的多媒体呈现,并在资源不足时实现优雅的呈现退化。
