SMIL supports synchronization and nice screen form environments among various multimedia data. Thus it is utilized widely in the fields of internet virtual lecture, internet broadcasting, and so on. Those kinds of system which can be applied flexibly in spite of the change of environments are required continuously with important issue, and depending upon the trends the function of SMIL is upgraded step by step. In this paper main function of SMIL is analyzed and modeled depending upon object oriented methodology. Also I propose some class model which is inspired iron service combinator. Suggested class model can be tuned by user easily if he wants to optimize system environments.
