Protocols and Systems for Interactive Distributed Multimedia: Joint International Workshops on Inter

Interactive Distributed Multimedia Systems (IDMS) and Protocols for Mul- media Systems (PROMS) have been two successful series of international events bringing together researchers, developers, and practitioners from academia and industry in all areas of multimedia systems. In 2002, for the ?rst time, these two workshops were held jointly, in what we hope was the ?rst of a new series of challenging and topical international workshops. IDMS/PROMS 2002 contributed to scienti?c, strategic, and practical - vances in the area of distributed multimedia applications, protocols, and - telligent management tools, with emphasis on their provision over broadband networks. Along with tutorials, regular papers and technical demonstrations, IDMS/PROMS 2002 resulted in high-quality original work. The areas of interest of IDMS/PROMS cover mobile multimedia systems, multimediamiddleware, multimediacommunicationprotocols, quality-of-service issues, resource management, next-generation Internet, active and program- ble networking for multimedia applications, multimedia-speci?c mobile agents, multimedia distribution and transport, multimedia tra?c engineering, multi- dia encoding and compression, ubiquitous computing, multimedia applications, development tools for distributed multimedia applications, performance of p- tocolsandapplications, multimediacontentmanagement, serviceaccess, acco- ting and tari? policing for multimedia teleservices, and standards (e.g., MPEG) and related issues. The IDMS/PROMS 2002 call for papers attracted 112 submissions from Asian, Australian, European, North American, and South American countries. These were subject to thorough review work by the Program Committee m- bers and additional reviewers who carried out their work using a specially built conferencesystem, WebChairing, developedinCoimbrabyFlordeUtopia, which allowed full control of the submission and reviewing processes.
