摘要： 描述了一种用于区分服务的MPEG-4多媒体内容分类机制。它通过向MPEG-4系统结构中加入一个新的媒体QoS分类层,把具有相近QoS性能需求的MPEG-4 AVO分为一类并映射到区分服务中。新的媒体QoS分类层采用一种对于应用层和网络层均透明的分类算法对MPEG-4 AVO进行分类。给出了该算法的结构和设计原则。

Abstract: This paper describes a mechanism of MPEG-4 multimedia content classification for differentiation service.Through adding a new media QoS classification layer to the MPEG-4 system architecture,this mechanism classifies the MPEG-4 audio visual objects(AVOs) that have similar QoS requirements into one class and maps the classification to the differentiation service.The new Media QoS classification layer uses an algorithm that is transparent to both the application layer and the network layer to classify the MPEG-4 AVOs.The architecture and designing principles of the algorithm are proposed.
