摘要：
In a method for synchronizing the presentation of static and dynamic components of an interactive multimedia document, the document and its dynamic and static components are defined in the system by means of objects. Synchronization data is provided in each object relating to times of presentation in a logical temporal frame of reference derived from a coded temporal frame of reference. In the object corresponding to the multimedia document and in each object corresponding to a static component, synchronization data is provided relating to a time of presentation in a physical temporal frame of reference. In the object corresponding to a dynamic component, synchronization data is provided relating to times of presentation in the coded temporal frame of reference. The synchronization data is processed on each change of speed of presentation of the multimedia document to coordinate the presentation of the components of a dynamic nature and the components of a static nature of the latter.
