Contributed by HTTP and XML, Web service is becoming the component called through the Web. In this article, we describe and analyze some current distributed object technologies,and then introduce the emerging Web Service technology. We introduce and analyze the two software strategies: Microsoft . NET and Sun ONE. Web Services will transform the current isolated Internet Web into interconnected services.展开更多

The heterogeneity and lacking of QoS guarantee make the application of this technique a challenge. In this paper, we analyze the difficulties in streaming media multicast design, survey technologies that have been proposed for it. We also discuss several congestion control and error control mechanisms. Finally we present some remained issues for further research.展开更多

The other is mobile wireless computing. The former can be implemented efficiently on the traditional wired network,such as the accession of multimedia information,real-time broad-cast. But due to the limitation of the wireless environment,the latter hasn't been able to support the video transport efficiently. Obviously,the combination of these two technologies,video service over wireless network,may be a killer application and in turn advances both of them. This paper summarizes the challenges of this field and introduces some possible solutions.展开更多

The collaborative system,developed with MediaCoKit, has a friendly GUI and a good accessibility for users. And group awareness is supported in terms of multimedia presentation,the presentation including both video and audio media. We discuss the key issues of the toolkit such as data sharing object,multimedia components,workspace awareness and then detail its implementation.展开更多
