基于面向对象层次模型的网络多媒体课件开发平台

在开发网络多媒体课件非线性编辑制作平台的过程中,为了优化其功能和结构,采用面向对象的层次结构模型,介绍了该模型的概念、功能特点及在平台中的应用,构建信息资源体结构及其数据结构(带头结点的双向非循环链表),讨论了该平台同步编辑器的设计与实现,包括多媒体的同步合成、参考点的同步模型,并通过研究给出其同步算法。其中,算法的实现,是通过使用队列来存储视频流和进行相关的同步与交互操作。

Developing Platform of Network Multimedia Courseware Based on Object-Oriented Layered Model

During the process of developing the nonlinear editing and making platform of network multimedia courseware,constructs the structure of information resource and its data structure(doubly linked non-circular list with head node) using the object-oriented layered model for making its function and construction better.Introduces the definition,function and characteristic of model,as well as application in this platform.Then discusses the design and implementation of synchronous editing in this platform,including synchronization and synthesizing of multimedia resources,synchronous model of reference point and the synchronous algorithm according study.The algorithm implements according queue which stores video stream and accomplishes synchronous and interactive operation that pertinent.
