An object-oriented software design for distributed videoconferencing system

A layered model based on objects for a distributed videoconferencing system is developed. The object orientation of various components consisting of the system and the semantic relations among multimedia are specified also. In this model, the object orientation decomposes the multimedia data streams into a set of objects on I/O level, processing level and network transport level, with different objects handled in parallel. So, it is easier to implement the model by using a "dataflow programming" style. Features of this model are analyzed and techniques used in system implementation are presented in brief.
