The field of multimedia software engineering is still unexplored and in a quite virgin state. Multimedia engineering is an emerging area combining software engineering, multimedia computing, visual languages and visualization. An analysis of how visual modeling of structure and dynamic behavior of a multimedia application differs from modeling conventional software yields the need of specific modeling procedures and languages. Therefore, multimedia application process has been truncated to implement-and- test methods. There are no specific multimedia development processes nor graphical notations adapted to them. In order to fill this gap we introduce a hybrid of OOM (Object Oriented Modeling) adapted to the specific needs of multimedia applications. Here, will be presented an innovative approach of multimedia software engineering from two different, yet complementary, perspectives: 1. The application of software engineering principles properly tailored to the development of multimedia applications and systems.
