| 摘 要： | 多媒体演示文档的协同菱对文档本身的结构与同步模型提出了一定的要求。为了便于面向对象的实现以及灵活多粒度的共享，提出了一个协同多媒体著作工具中分布交互式多媒体文档的同步模型。在此模型中，文档结构分为三层：页面层、对象组层及单媒体对象层，根据各层的特点，其同步分别采用基于跳转、基于事件及基于时间的策略。

| Abstract: | The collaborative authoring of multimedia documents poses some special requirements of the structure and synchronization of documents. In order to make the object-oriented implement of these documents easy and multiple granularity sharing of them flexible, we propose here a synchronization model for complex distributed interactive multimedia document in collaborative authoring tools. This hierarchical mode consists of three layers: page, object group, and medium object layer. Considering the characteristics of these layer, the synchronization of them are of jump-based, event-based, and time-based mode respectively. |
