基于复合文档的多媒体自适应传输策略模型AMTM及其实现

Compound Document Based Adaptive Multimedia Transport Model (AMTM) and Its Implementation

计算机网络的迅速发展 ,推动了应用的层出不穷和多媒体数据的急剧膨胀 ,促使网络、终端和用户的差异性和数据的单一性之间的矛盾加剧 .文中提出了基于复合文档的自适应传输策略模型 AMTM(Adaptive Multime-dia Transport Model)和相应算法 ,并在此基础上实现了一个自适应的多媒体传输架构 AMTF(Adaptive Multime-dia Transport Framework) .它对复合文档中包含的多媒体数据进行动态的变换处理 ,使文档能适应网络、终端和用户的差异 ,而同时又不造成数据冗余 ,为构筑具有自适应传输特性的应用提供了底层的支持 .

With the rapid development of computer network, there appear so many new applications and Multimedia data that the chasm, which between the singularity of data sources and the variations of network, terminal devices and users, grows wider and wider. This paper proposes a novel compound document based Adaptive Multimedia Transport Model, known as AMTM, and implement a framework for adaptive multimedia delivery, which can dynamically transform the multimedia data to accustom them to the variations as said above without too much data redundancy, so provides a supporting platform for various applications with adaptability for multimedia delivery.
