Interactive multimedia services on Internet

The combination of multimedia technology and Internet is currently attracting a considerable amount of attention from developers and potential users alike. However, although many new products are being announced and marketed, the majority of the information on the Web still consists of just images and text, and the few ''multimedia'' items are in reality only short video clips with little interactive functionality. Our prototype implementation of an interactive multimedia system, based on the integration of commercial products, provides some original functions for enhanced user interaction, whilst still maintaining complete compatibility with the rapidly evolving context of the Web. It also allows the same ''product'' to be delivered over connections of different capacity by selectively decreasing the bandwidth dedicated to the video part of the data.
