Design and implementation of a dynamic VRML-browsable, movie on-demand system distributed over Internet

This paper presents the design and the implementation of the Virtual Video Gallery (VVG), an advanced distributed video on-demand system accessible through a dynamic virtual world, which mimes an art gallery where movie posters are exhibited The design phase is driven by object-oriented modeling techniques which depend on UML and its extensions purposely suited to model multimedia information systems. The implementation centers on an approach blending (i) Java, which provides powerful computing, multimedia and networking capabilities, (ii) VRML, which supports an easy construction of complex virtual worlds, and (iii) WWW facilities.
