基于OCPN的SMIL文档创作平台设计与实现

Design and Implementation of SMIL Documents Authoring Platform Based on OCPN

基于SMIL的多媒体文档创作平台是目前的应用研究重点。SMILAuthoringTool(SAT)创作平台在参考了SMIL2 .0定义基础上 ,以OCPN为多媒体同步时序定义的基本模型 ,分析了国内外现有的系统优缺点之后 ,利用面向对象的方法实现。SAT相对于已有的系统而言 ,它使用树形组织结构和OCPN对节点之间的时序和节点内部的详细同步信息进行设置 ,二者互相补充 ,可使用户进行简单的同步时序设置。

How to author a SMIL document easily and efficiently is important for researchers of Multimedia. SMIL Authoring Tool(SAT)authoring platform is implemented based upon SMIL2.0 specification using a synchronization model OCPN (Object Composition Petri Net). After analyzing the strongpoint and defects of existing authoring platforms,SAT is implemented using Object Oriented method. To the best of our knowledge,compared to the existing authoring tools,SAT makes use of tree-like architecture and OCPN to set the detail of multimedia synchronization. The tree-like architecture and OCPN work together to make users author a SMIL file easily.
