摘要
文中旨在研究基于MPEG-4技术的面向对象多媒体同步。所采用的方法是在分析现有多媒体同步模型的基础上,结合MPEG-4系统同步机制和高级同步模型(FlexTime),设计面向对象的多媒体同步模型,以实现MPEG-4中各媒体对象间同步。由此方法设计的层结构同步模型是一种有效可行的多媒体间同步的实现方法。和其它的多媒体间同步方法相比,这种方法在基于对象的多媒体的传输过程中携带较少的时间信息来完成对象间的同步,并且增强了基于对象内容交互的灵活性。
The paper focuses on multimedia synchronization based on MPEG-4. By analyzing existing multimedia synchronization model, the paper designs the object - oriented model to synchronize all MPEG - 4 multimedia objects, based on MPEG - 4 system synchronized mechanism and the Advanced Synchronization Model （FlexTime）. The proposed layered structure synchronization model is an effective and feasible method of multimedia synchronization. Compared with other methods, the proposed one uses less time information to finish object synchronization during the object - oriented multimedia transmission and improves the flexibility of the object - oriented content interaction.
