摘要

在本文中,我们展示了如何在编写阶段格式化SMIL多媒体文档的代码,以改进其执行过程中的数据传递。这允许减少延迟影响并及时恢复所请求的数据。最后的代码倾向于在考虑带宽和缓冲区限制的情况下更有效地管理请求调度。它是在前者的基础上构建的,同时添加了预获取命令,这些命令的参数是通过使用SMIL文档提取模式来计算的。后者考虑了每种媒体的特性、媒体间的同步以及一些时间信息。

Efficient Bandwidth and Buffer Management for Multimedia Data Download
In this paper we show how to format the code of a SMIL multimedia document during the authoring stage in order to improve the data delivery during its execution. This allows to reduce the latency effects and to recover timely the requested data. The final code tends to manage more efficiently the request scheduling while considering bandwidth and buffer limitations. It is built from the former while adding pre-fetching commands whose parameters are computed thanks to the use of the SMIL document- extracted pattern. The latter considers the characteristics of each media, the inter-media synchronizations, and some time information.
