Abstract: This paper firstly introduces the current stream-media synchronal standards-SMIL and HTML+TIME, and compares their synchronal models. Then considering the characteristic of stream-media synchronization in the distance learning, using the model that is composed of a main axis and a subsidiary one, the synchronal standard SlideShow based on XML is implemented. Based on the results of Web mining, a high performance and intelligent media order program system that is according to the characteristic of the distance learning is implemented.
