摘要
本文首先讨论了多媒体的核心技术问题，提出了人机界面设计、多媒体同步模型是多媒体技术的两大关键课题。接着分析了当前最为流行的三种多媒体同步模型，指出了其优缺点。本文从多媒体制作／播放的特点、多媒体外部设备接口的要求以及面向对象技术、可视多媒体编程这四个角度分析了理想的多媒体同步模型的特点，并据此提出了多媒体二级同步模型。最后，对多媒体二级同步模型工作机制和优缺点作了必要的分析。
We first discuss the core technology of the multimedia technology,and promulgate that the multimedia human-computer interface and the multimedia synchronistic model are the key of the multimedia technology. Then we analyze three most popular multimedia synchronistic models and point out their advantages and disadvantages. We give the features of an ideal multimedia synchronistic model in four aspects-the features of multimedia program and display, the requirement of multimedia facility interface, O-O technology, and visualizing program. Based on these features, a new model-multimedia synchronistic model with two levels is proposed. Finally, we introduce its working process and discuss its advantages and disadvantages.
